See nora.c, vmax301.c = and > octagon-5066.c for examples. I've got an Intel StrataFlash so it's both 16 bits and CFI compliant. I quickly checked the files you mentioned and this all seems very simple.=20 But I've got a few questions : what is nora.c for (from the name, I guess it's a NOR flash and from the code I guess it's CFI but that's all I know)? and what does SBC stand for ? --=20 S=E9bastien C=F4t=E9 To unsubscribe, send "unsubscribe mtd" to majordomo@infradead.org
