RE: Third-party firmware PoC...
Quote:Hey! little question, what happens if you upload a broken elf file?If the code crashes, the calculator reboots. However, I haven't tried to upload flat out invalid ELF files (wrong sections, wrong loading addess, wrong start address, etc.), as it doesn't make much sense. You can try for yourself Quote:does the firmware utility always recover the calculator to the "upload" mode?Holding Symb before and after releasing the Reset button should always be able to recover the calculator, indeed. That is, unless one destroyed the area where the contents of BXCBOOT0.BIN are stored, triggering intentional bricking. Quote:Maybe there is a similar kit to play with in a more comfortably way?Yeah, there are several S3C241x/S3C244x-based kits around, but there's no way they have the same GPIO assignments as the Prime has, so they wouldn't fully help. A computer-based emulator would help, I've gathered several relevant links on the TI-Planet hpwiki. |
