tkeyimage

A tool to parse or generate partition table or entire filesystems for the TKey.

  • Parse with -i file.bin for "input".
  • Generate with -o file.bin for "output".

Add -f to parse or generate an entire flash image file.

Usage

Inspect a partition table dump

Dump the entire data from flash, then inspect:

$ tillitis-iceprog -R 1M dump.bin
$ ./tkeyimage -i dump.bin -f
INFO: main.Flash struct is 1048576 byte long

Read only the first copy of the partition table from flash to file, then inspect:

$ tillitis-iceprog -o 128k -r partition.bin

Generate a partition table

If you want to generate just a partition table:

$ ./tkeyimage -o partition.bin

With an app in slot 0, filling in the size in the partition table:

$ ./tkeyimage -o partition.bin -app0 ../../fw/testloadapp/testloadapp.bin

Generate flash image

The program can also generate an entire flash image for use either with real hardware or qemu.

Generate like this:

$ ./tkeyimage -o flash.bin -f -app0 ../../fw/testloadapp/testloadapp.bin

Using -app0 is mandatory because TKey firmware won't start without an app in slot 0.

The qemu args to use to run with flash.bin as the flash are:

-drive file=flash.bin,if=mtd,format=raw,index=0

A complete command example:

$ qemu-system-riscv32 -nographic -M tk1-castor,fifo=chrid \
-bios qemu_firmware.elf -chardev pty,id=chrid -s -d guest_errors \
-drive file=flash.bin,if=mtd,format=raw,index=0
