![]() Do not use uninitialized cmd_reset; issue both AMD and Intel reset commands instead From a short test, it looks like AMD-style flash roms treat *any* unknown command write as a reset, at least when in CFI Query mode, so issuing the Intel reset command to AMD-style flashs seems safe (from the small sample I have), plus the 3-cycle magic sequence should kick the state machine into the right state even without a reset command. Since the AMD-style flashs require the unlock sequence for real operation, I chose to try the AMD reset command first, so that Intel flashs do no see an invalid command prior to the CFI query. I have tested the patch on AM29LV320-style flashs from Fujitsu and Macronix, plus Intel StrataFlash.
