Hi!
I have the following problem: the flash memory I need to program is
usually at sleep. So I must wake-up it, sending a "Release from
Power-down" (0xAB) command.
This command (and the one to make it sleep again: Deep Power Down
(0xB9)), seems to be widely supported by SPI flash chips.
The most annoying detail is that you must try to wake-up the memory,
even before you really know the memory is there. The memory won't reply
an ID when sleeping.
Right now I have a patched flashrom with support for a new SPI cable. I
added the wake-up/sleep commands to the cable, but it looks confusing,
because this is something that belongs to the memory.
Any advice?
Regards, SET
