Several people asked me recently how to decrypt atj2127 firmware. Someone
posted on github (https://github.com/nfd/atj2127decrypt) a decrypt utility
clearly reverse engineered from some unknown source. The code is an absolute
horror but I concluded that ATJ changed very little between ATJ213x and ATJ2127
so I added support for the ATJ2127, credit to this github code that I stole
and rewrite (code was under MIT licence). At the same time do some small code
cleanups.
Note that there is not 100% sure way that I know to distinguish between the
two firmware types, so the code tries to do an educated guess to detect
ATJ2127. If this does not work, use --atj21217 option. Also note that contrary
to the github tool that decrypts and unpack in one go, this tool only does one
step at once. So first decrypt: HEX -> AFI, then unpack AFI -> files.
I also added for a different version of AFI. Based on AFI files I have, there
are, I think, two versions: the "old" ones (pre-ATJ213x) and "new" ones. The
tool only supported the new one but for some reason the ATJ2127 uses the old
ones without a mostly empty header. Strangely, even this mostly empty header
does not seem to follow the old layout as reverse engineered by the s1mp3
project (https://sourceforge.net/p/s1mp3/code/HEAD/tree/trunk/s1fwx/heads.h),
so in fact there might be three versions. In any case, only the header is
different, the rest of the file is identical so at the moment I just don't
print any header info for "old" files.

The devinfo request returned the raw data, now the tool prints the various

one is untested because it's only supported starting from A10 or A20. There is
still a problem with the dpcc prop: although it should work for DEVINFO, it does
not, despite the fact that the get_dev_info command works and is internally (on
the Sony) translated into a dpcc request. I keep the code just in case.

Since we can catch exceptions like data aborts on read/write, it takes very
little to also catch exceptions in calls. When extending this with the catching
of illegal instructions, the call instruction now becomes much more robust and
also for address and instruction probing. Since we can catch several types of
exception, rename set_data_abort_jmp to set_exception_jmp. At the same time,
simplify the logic in read/write request handlers. Also fix a bug in ARM
jump code: it was using
stmia r1, {..., pc}
as if pc would get current pc + 8 but this is actually implementation defined
on older ARMs (typically pc + 12) and deprecated on newer ARMs, so rewrite the
code avoid that. The set_exception_jmp() function now also reports the exception
type.

The JZ misc allows to enable and test SRAM.
The XBurst code uses the coprocessor interface to analyse the cpu. It also
provides a test platform for various features like EBASE and exceptions.
I was able to test and confirm that on jz4760b (thus xburst), EBASE works

to support vector interrupts but this is untested. The values in ConfigX

This is needed on the jz4760b because if some data is loaded to DRAM, then it
is cached and a disaster lurks if dcaches/icache are not flushed. Targets that

This is a register description file for the JZ4760B. There are several
details worth noticing:
- it was obtained by gathering information from several sources/headers, but
since there are inconsistencies between them about the exact differences
between JZ4760 and JZ4760B, this file probably contains some errors
- the register names are not the same as the manual ones (which are not the
same as the one in the headers anyway): I dropped the "R" suffix on most
registers because it's redundant
- Ingenic likes to have read-only registers and then set/clr registers, with
very confusing names like DIR/DIRS/DIRC: in the file, the set/clr registers
are described as set/clr variants of the original register
- Parts of the description were obtained programmatically, which explains why
there are empty nodes or partially undocumented registers

The old code had some annoying way of dealing with padding by adding explicit
instructions to the stream, which is 1) ugly 2) not in par with freescale
tools. The trick, which this new version implements, is to put the useful length
of the section in the section header, and the actual (with padding) length in
the boot tag. This way the tools can just ignore padding instruction by
reading the section header, and the bootloader can still load the image because
it uses the boot tags.
Also correctly handle the case where the first section does not start right
after the header (there is a bug in freescale tools for this case by the way).
There is an ambiguity in the way the padding instructions should be encrypted:
the bootloader should logically treat them as regular instruction of the section
stream, but it appears the freescale tools do not generate them as part of the
stream and instead encrypt them like boot tags, which is stupid because there
is no way the bootloader could decrypt them, and anyway we don't care because
the bootloader doesn't decrypt them at all.

The new code gets closer to an actual bootloader:
- it provides a menu with three options: Sony, Rockox, tools with icons (and
extracts the Sony logo from the NVP)
- the dualboot install script now creates a symlink from /.rockbox to
/contents/.rockox which is necessary to run rockbox
- more text drawing / framebuffer functions
In the long run, we will move this under bootloader/ and rbutil/ and also use
firmware/ drawing facilities, at the moment we use OF display program which
is slow and creates some flickering.

There must be an evil genius in Sony's Walkman division. Someone who made sure
that each model is close enough to the previous one so that little code is needed
but different enough so that an educated guess is not enough.
Each linux-based Sony player has a model ID (mid) which is a 32-bit integer.
I was able to extract a list of all model IDs and the correspoding name of
the player (see README). This gives us 1) a nice list of all players (because
NWZ-A729 vs NWZ-A729B, really Sony?) 2) an easy way to find the name of player
programatically. It seems that the lower 8-bit of the model ID gives the storage
size but don't bet your life on it. The remaining bytes seem to follow some kind
of pattern but there are exceptions.
From this list, I was able to build a list of all Sony's series (up to quite
recent one). The only safe way to build that is by hand, with a list of series,
each series having a list of model IDs. The notion of series is very important
because all models in a series share the same firmware.
A very important concept on Sony's players is the NVP, an area of the flash
that stores data associated with keys. The README contains more information but
basically this is where is record the model ID, the destination, the boot flags,
the firmware upgrade flags, the boot image, the DRM keys, and a lot of other stuff.
Of course Sony decided to slightly tweak the index of the keys regularly over time
which means that each series has a potentially different map, and we need this map
to talk to the NVP driver. Fortunately, Sony distributes the kernel for all its
players and they contain a kernel header with this information. I wrote a script
to unpack kernel sources and parse this header, producing a bunch of nw-*.txt
files, included in this commit. This map is very specific though: it maps Sony's
3-letter names (bti) to indexes (1). This is not very useful without the
decription (bti = boot image) and its size (262144). This information is harder
to come by, and is only stored in one place: if icx_nvp_emmc.ko drivers, found
on the device. Fortunately, Sony distributes a number of firmware upgrade, that
contain the rootfs, than once extracted contain this driver. The driver is a
standard ELF files with symbols. I wrote a parsing tool (nvptool) that is able
to extract this information from the drivers. Using that, I produced a bunch
of nodes-nw*.txt files. A reasonable assumption is that nodes meaning and
size do not change over time (bti is always the boot image and is always
262144 bytes), so by merging a few of those file, we can get a complete picture
(note that some nodes that existed in older player do not exists anymore so
we really need to merge several ones from different generations).
The advantage of storing all this information in plain text files, is that it
now makes it easy to parse it and produce whatever format we want to use it.

0e2b490 introduced rework of usb driver which was broken. It was reverted
in f2da975 to restore hwstub functionality on ATJ.
This commit reenables usb rework AND fixes remining issues.
The problem was with 0 length OUT thransfers. Additionally
a few cleanups were made.

Sony added extensions to the frambuffer interface. It is important to take them
into account since the OF uses them and might leave the framebuffer in an
unusual state which would make the dualboot not display anything. Also rework
the dualboot code so that it can boot rockbox (not doing anything at the moment),
display all tools or boot the OF.
Change-Id: Ia0f589c9ec8558f375270841503c0964aff07f0b
At the moment, the script install_duaboot does the following:
- rename SpiderApp to SpiderApp.of (unless it already exists)
- install payload as SpiderApp
- fixes permissions
Since SpiderApp is the main app, it will execute instead of the OF.
The current dualboot code (dualboot.c) is still a preliminary but the current
version displays an "all tools" menu to choose for. When exitting the menu
using BACK, it will run the OF.
With the modifications made by the install script, it should not be possible
to break the device. In the worst case scenario, the dualboot code crashes
and it restarted by the sysmgrd, or hangs. A safe way to recover is to plug
the USB cable and reset the device: the system manager will then start the
USB app and one can reflash the device if necessary.

Since the nwz_lib does not have any nvp code yet, it's quite of ugly hack

The new search has two new features:
- it takes advantage of the fact that DES keys are only 56-bit long (and not 64)
- it is now multithreaded
As a proof of concept, I ran it on the A10 series firmware upgrade and was able
to find the key in a few seconds using 4 threads. The search is still limited
to ascii hex passwords (seems to work on all devices I have tried thus far).

This is code is intended to development into a library of code for the NWZ that
will be useful to write the "bootloader" on those device. At the same time, it
comes with test programs that are easy to run in firmware upgrade mode and also

- test_display: simply prints two messages using /usr/bin/lcdmsg
- test_keys: displays input key event

This new header generator works differently from the previous one:
- it uses the new format
- the generated macro follow a different style (see below)
- the generated macro are highly documented!
- it supports SCT-style platform or RMW-style ones
Compared to the old style, the new one generate a big set of macros per
register/field/enum (loosely related to iohw.h from Embedded C spec). The user
then calls generic (names are customizable) macros to perform operations:
reg_read(REG_A)
reg_read(REG_B(3))
reg_read_field(REG_A, FIELD_X)
reg_read_field(REG_B(3), COOL_FIELD)
reg_write(REG_A, 0x42)
reg_write_field(REG_A, FIELD_X(1), FIELD_Y(3), IRQ_V(FIQ))
reg_write_fielc(REG_B(3), COOL_FIELD_V(I_AM_COOL), BLA(42))
the following use RMW or SET/CLR variants, depending on target:
reg_set_field(REG_A, FLAG_U, FLAG_V)
reg_clr_field(REG_A, FIELD_X, FIELD_Y, IRQ)
reg_clr_field(REG_B(3), COOL_FIELD, BLA)
the following does clear followed by set, on SET/CLR targets:
reg_cs(REG_A, 0xff, 0x42)
reg_cs(REG_B(3), 0xaa, 0x55)
reg_cs_field(REG_A, FIELD_X(1), FIELD_Y(3), IRQ_V(FIQ))
reg_cs_field(REG_B(3), COOL_FIELD_V(I_AM_COOL))
The generator code is pretty long but has lots of documentation and lots of
macro names can be customized.

Although the jz4740 contains a similar tool to usbboot, its command-line

This commit adds support for the version of the hwstub library, which requires
a lot of changes. It also adds some editing features, such as register access
and much better editing of fields using the mouse (double click on a field
to be able to resize and move it).
Change-Id: I3c4e4cc855cb44911c72bc8127bad841b68efe52
Registers (and variants) can now specify the type of access supported:
- unspecified: for variant means same as register, for register defaults R/W
- read/write
- read only
- write only
Backward compatibility is preserved by setting access to unspecified by default.
Change-Id: I3e84ae18f962a45db62f996a542d08405d05b895
Also use this opportunity to cleanup support for multiple devices: the shell
now supports dynamic changes in the device and will call init() everytime
a new device is selected, to prepare a new environment. The shell now
honors register width on register read/write. The shell also provides access
to variants as follows by creating a subtable under the register using the
variant type in UPPER case and having the same layout as a register.
For example if register HW.GPIO.DIR has variants "set" and "clr", those can
be used like this:
HW.GPIO.DIR.SET.write(0xff)
HW.GPIO.DIR.CLR.write(0xff00)

Rewrite the hwstub library in C++, with a clean and modular design.
The library was designed from the ground up to be aware of multithreading
issues and to handle memory allocation nicely with shared pointers.
Compared to the original library, it brings the following major features:
- support for JZ boot devices, it is very easy to add support for others
- support for network transparent operations (through sockets): both tcp
and unix domains are support

A v2 register description file can now include register variants and instances
addresses can now be a list (previously it could only be a stride or a formula).
Update the library to deal with that. The convert option of swiss_knife was
updated and one incompatible change was introduce: if a v1 device has several
addresses, those are converted to a single v2 instance with list (instead of
several single instances). This should have been the behaviour from the start.
Swiss_knife can now also convert regdumps, in which case it needs to be given
both the dump and register description file. Also introduce two register
descriptions files (vsoc1000 and vsoc2000) which give more complicated examples
of v2 register description files.

With this you can upload and run code on DSP core in atj213x.
The files can be produced using as2181. You can download
this assembler from https://github.com/wodz/as2181
You should use extended mode (-x switch) since DSP core
in atj is non standard and uses 24bit operands.
PX register has different meaning as well and is used as MSB
when loading other registers with immediates (immediate field
is 16bit in instruction so to set register to 24bit value
you need to store MSB in PX prior to this).
MAC MR is 56bit accordingly.
HIP interface seems to be mapped at standard addresses
(except that regular 218x doesn't have HIP).
Have a fun!

This tool can pack/unpack a jz4760 archive (like the one used for the fiio
x1/x3/x5), and can descramble/scramble (it's the same operation) a firmware
file (the sys.bin file in the archive). I did my best to keep the compatibility
with the leaked Fiio/Ingenic tool which has the same name.
I wrote the tools from scratch, but here are some remarks:
- the format used is a slightly modified IHFS used in the older JZ4640 series,
I used the information on the wiki about the IHFS format
- the CRC computation done was already reversed engineered by someone on the
forums but I realised this later
- There are a few unknown fields in the headers, see comments in the source code
- The firmware scrambling was discovered by pure guess, I realised there were
some repetitve sequences, some I guessed it was a rotative XOR and ran some
analysis to find the most probable sequence
