Do you have equipment to analyze the signals to the flash chip? Ideally a logic analyzer, but a 20MHz scope can work too.
That's ideally. In reality, several things are absent.
A scope is easier to come by though. I have one, but I don't have a board with SPI flash.
There's no other way to debug this code. :\
Except to rev-eng the code, original flasher uses. But this isn't suitable for me (too much time is required for analysis).
If the new software doesn't work even though it's implemented "just like" the original flasher we still need to see what's (not) happening on the bus.
