Hold "Play" to boot the OF, or boot it from the recovery menu
by holding "Vol. Up". If you had the hosted port installed on your
player before installing the native port, you'll still have to go
through the hosted bootloader.
A couple notes:
- When booting from the menu, the recovery menu disappears, then
reappears before going into the OF.
- You need to hold the play button for like a half second after the
blue light comes on in order to get into the OF.
The recovery appears to be there, but it doesn't seem to be intended
for end users - it just says "Updater V1.1 - Insert TF Pls". I haven't
tested it beyond seeing that it boots, so I'm going to comment it out

The 100 mA USB current limit added in commit 90dd2f84a9

Often 100 mA isn't enough to power the player, never mind
charge the battery, so revert to the old behavior of only
limiting charge current.
Given that the original firmware on these devices isn't
following the USB spec to the letter, it's probably not
worth trying to make Rockbox do so unless and until it

This problem actually had nothing to do with USB boot; it's
because the cable is plugged in when the USB mode menu item
is selected. The USB thread detected the select button press
and went into charge-only mode (as it usually does when you
hold down a key in Rockbox). This is fixed by having the USB
thread ignore most keys in the bootloader.
USB connect events are delivered via the button queue, and
there were also cases where the connection could be missed
if the event happened within another UI screen. This should

ignore most completions on EP0, but it only did so after

It turns out the prescaler fields in OST_CTRL are 2 bits wide,
not 3. The programming manual (as usual) is ambiguous and its
diagram shows 2-bit wide fields, but the bit positions in the
text give a 3-bit wide field. Ingenic's Linux code and my own
testing shows that they are, in fact, 2 bits wide.
This caused the OST2 divisor to be 16 instead of 4; the OST1
divisor was correct. This means that all udelay/mdelay calls
took 4x longer than they should've. After this change the OST2
prescaler will be 4, as intended, and udelay/mdelay calls will

When performing an OUT transfer which is not a multiple of the
max packet size, the last packet of the OUT transfer should be
a short packet. However, there's no guarantee the host sends
the expected amount of data in the final packet.
The DWC2 USB controller handles this case by accepting any size
packet and copying it out to memory. So if the packet is bigger
than expected, it'll overrun the caller's buffer and Bad Things
will happen.
The USB 2.0 spec seems to endorse this behavior. Section 8.5.1
says "an ACK handshake indicates the endpoint has space for a
wMaxPacketSize data payload." So it is possible that other USB
controllers share the DWC2's behavior.
The simplest solution is to force all USB RX buffers to be big
enough to hold the transfer size, rounded up to a multiple of
the max packet size. For example, a transfer of 700 bytes would

Write -1 to AIC_DR to initialize the "last sample"
to -1 in order to prevent power-on clicks.
It appears necessary to completely fill the FIFO,
otherwise I was able to get a click out of it, however
uncommon it was.
Not only does this prevent a click when first
playing a song after power-on, but it also seems to prevent
any click at all when powering on - previously, a small
click may have been heard when first booting.

Previously it used the last sample, which turns out to be broken.
The AIC appears to send out a random non-zero sample continously
after boot -- probably because the last sample is uninitialized by
the hardware. Disabling playback is supposed to make it send zero
samples irregardless of the LSMP bit according to the docs, but it
doesn't seem to work this way.
- Change eliminates the white noise heard on the M3K after boot.
- Change has no adverse effects on the Q1.
- Leave Eros Q on the old setting since sending zeros exacerbates
clicking due to DAC's automute feature.

According to a forum user, there's an audible click when changing
the volume between -32 and -32.5 dB with some headphones. Fix this
by not (ab)using the DAC digital mixer for volume control.
The mixer only provides an extra -6 dB of hardware volume range,
so the only side effect is that software volume will now kick in
at -32 dB instead of -38 dB.

Upon getting a USB reset, the USB core will update charging
current by calling usb_charging_maxcurrent_change(). On all
current X1000 targets this may cause a hang, since changing
the charge current involves a blocking I2C transaction.
Eg. if the host issues a reset when we're already configured
as part of error recovery, the change from 500 mA -> 100 mA
will cause a hang.

Adjust the battery scale to be a little better. I've set
the 100% (discharge) point to be where the battery sags to
when it is done charging but still plugged in.
Not quite sure how best to set the charge scale, it's just
equal to the discharge scale for now.

IMHO the current name is somewhat misleading:
- usb_drv_send() is blocking and we have usb_drv_send_nonblocking()
for the non-blocking case. This inconsistent naming can only
promote confusion. (And what would we call a blocking receive?)
- Other hardware abstraction APIs in Rockbox are usually blocking:
storage, LCD, backlight, audio... in other words, blocking is the
default expected behavior, with non-blocking calls being a rarity.

A reasonable default assumption for a user
would be that they can plug their device into
a USB AC adapter and it will charge with as much
current as it reasonably can. With the previous
default, an AC adapter will only do 100mA, basically
a trickle charge.
Make this configurable default per-device, so as not
to break old devices without testing.
Define TARGET_USB_CHARGING_DEFAULT to USB_CHARGING_FORCE
to use the new default.
Tested on both erosQ Native and M3K.

'Bugfix' mono_bitmap_part reads ahead in the buffer,
if the height is <= char bit pixels other memory gets read
found with [Address Sanitizer]
also g#3332 since this is clearly a problem across the code
instead place the check for height < 8 in the lcd_mono_bitmap_part function
second try places the check above the negative y offset
this was causing glitches on the Q1 and likely other TS targets
since a negative y was added to height it made it < CHAR_BIT setting
stride = 0 even though the bitmap was >= CHAR_BIT high

Similar to the native port, the hosted port benefits from

What works:
- LCD: 16-bit RGB565
- all buttons, including scrollwheel
- SD Card
- Battery level and charging/not charging status
- USB
- audio
- sample rate switching
- HP / LO detect, with "safe" fixed LO volume -
LO volume will only be put to user-defined max volume
if headphones are not present.
- rtc
- Plugins build, tried a couple and they seem OK
- Bootloader, installable to nand via usbboot
What doesn't work:
- Dual Boot
- power on/off has intermittent, low volume audio click
(sometimes it's completely silent, sometimes there's
a click)
- Audio uses 16-bit volume scaling, so clicking/popping
is pretty bad at lower volumes - need 32 bit volume
scaling, 24 bit I2S data
- USB HID keys not yet defined
- no jztool support
Unknowns:
- Stereo Switch pins: Direction select, AC_DC
(probably not even hooked up)
- What is the actual purpose of the Stereo Swtich?
- How does the bluetooth module connect?
"Someday" stuff:
- get LCD working at higher bit depth
- Bluetooth

This relies on a macro, CRC32R_FAST, to select which version to
compile with. In tests the fast version is 2x faster at the expense
of requiring 960 more bytes for the lookup table. For now the default

this for ports where we can afford the extra storage and/or memory

- Audio playback works
- Touchscreen and buttons work
- Bootloader works and is capable of dual boot
- Plugins are working
- Cabbiev2 theme has been ported
- Stable for general usage
Thanks to Marc Aarts for porting Cabbiev2 and plugin bitmaps.
There's a few minor known issues:
- Bootloader must be installed manually using 'usbboot' as there is
no support in jztool yet.
- Keymaps may be lacking, need further testing and feedback.
- Some plugins may not be fully adapted to the screen size and could
benefit from further tweaking.
- LCD shows abnormal effects under some circumstances: for example,
after viewing a mostly black screen an afterimage appears briefly
when going back to a brightly-lit screen. Sudden power-off without
proper shutdown of the backlight causes a "dissolving" effect.
- CW2015 battery reporting driver is buggy, and disabled for now.
Battery reporting is currently voltage-based using the AXP192.

Debounce logic now handles both removal and insertion and verifies
the detection is stable for 100ms before taking any action.
This solves the bootloader "file not found" issue on the Shanling Q1.
It seems a false removal event was generated, causing the filesystem
to be automatically unmounted. Probably this is due to some transient
noise at boot. Delays didn't solve the problem, probably because the
bogus hotplug event was queued, and normal mdelay() would simply delay
event delivery.
