To test a build, use 'make tar' and send the tar to the unit. The bootloader will unarchive it and delete it before loading the main binary.
This is a temporary hack to make testing possible until we have a better way of sending a complete build.
Also enable writing to the disk by disabling the optimised write stubs.
