Im working on adding support for our board to u-boot.
I use legacy flash mode for our boot-flash. I however have some problems with it.
When using jedec probe to identify our flash. Im unable to do so with our 16bit device-id. In my opinion it seems like this actually wont work(?)
cmdset_amd_read_jedec_ids uses _one_ flash_read_uchar call to read out the device id(, if its not an amd extended one). The only way i could get this to work with our flash was to only put the lower 8bit in the dev_id field when adding an entry to the jedec_table.
Hm - right. You are probably the first one to use that code on a 16-bit non-CFI flash - for 16-bit flashs, the read will need to be changed, but I am not sure how exactly - I think we may need separate code depending on info->chipwidth, because 8-bit flashs only have an 8-bit ID.
Further on it seems like CFI_CMDSET_AMD_LEGACY is unsupported in flash_write_cfibuffer.
Right. Setting info->buffer_size = 1 in jedec_flash.c/fill_info() should make sure that part of code is never executed.
