Memory in Deep Power Down

[Salvador Eduardo Tropea]

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
