probe_jedec: id1 0x25, id2 0xe4
flash.h suggests that the manufacturer might be ASD:
#define ASD_ID 0x25
I did a search and found that the flash chip should be 2Mb. Therefore I guess the flash chip is AE29F2008. Could you verify that?
From this[0] page, it seems that AE29F2008 and AT29C020 behave in
similar way. If you are trying to read the content, maybe you can try a force read.
Hope I am giving some useful information.
