I can’t turn ON my phone anymore. I had everything working fine until the final step in the following:
$ host/osmocon/osmoload funlock 0x000000 0x10000
$ host/osmocon/osmoload ferase 0x000000 0x10000
$ host/osmocon/osmoload fprogram 0 0x000000 compal_loader.bin
$ host/osmocon/osmoload fprogram 0 0x002000 target/firmware/board/compal_e88/loader.e88loader.bin
I used loader.highram.bin instead of loader.e88loader.bin. I didn’t get any errors even after this step but then I couldn’t do anything with the phone.


Best regards,
Robert,

That said, I added some changes a while ago locally (not in the repo) to flash my c139 phone and haven't gotten any bricks yet (cross fingers). I was working on getting nuttx-bb flashed as a sole app on the phone, debugging startup problems and re-flashing repeatedly.
