Reply To: OSSC v1.8 freezing and behaving strangely

[rt]

Ha, the remote was indeed not in OSSC mode! 😅 Thanks for pointing that out, “problem” fixed.

Could the CRC errors possibly have something to do with my JTAG? I bought my USB Blaster more than 10 years ago for around 8 Euros; it’s certainly a clone. Since then, I’ve rarely used it, so I don’t really know how good (or bad) it really is. Working on Linux, by the way.

My OSSC still works perfectly after swapping out U10, so it looks like my flash broke halfway after some unknown incident which also burned the fuse. To help diagnosing a broken flash IC, maybe you could add a checksum check that can be invoked from the menu? That feature could compute the checksum from the firmware data stored on flash memory and compare it against the correct checksum stored right after the actual firmware data (or even use multiple checksums which cover smaller chunks of the firmware). Yes, this may sound like a useless feature, since damaged firmware should not be able to run at all. In my case, however, a complete update from the SD card, including checksum verification, passed with no errors, and the firmware even functioned correctly for a short time before it kind of disintegrated.

Oh, and it would be great if you could release a .jic file for v1.20 (and later).

Thank you for your time!
