I wouldn't recommend a CH341A for the same reasons Nico explained, and would suggest the same alternatives. I've done a lot of development on the Asrock B85M Pro4 (a completely different board, but also has a socketed DIP8 flash chip) and, for me, the most efficient development cycle is to use a flash emulator like the Dediprog EM100. However, flash emulators aren't cheap. Before I had the EM100, I simply moved the flash chip back and forth by hand, from the mainboard to a breadboard wired to a CJMCU FT2232HL mini module (external programmer) and viceversa. I added another DIP8 socket between the flash chip and the mainboard's socket, so that I could easily and quickly remove and replace the flash chip. > Aside from the mechanical question, I'd appreciate any advice about the > safety of externally programming the board.

If you remove the flash chip from the mainboard to reflash it, it's practically impossible to damage the board. > Cheers. > > _______________________________________________ > coreboot mailing list -- coreboot@coreboot.org > To unsubscribe send an email to coreboot-le...@coreboot.org Best regards, Angel _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org
