Having just taken delivery of an ep8248e, I'm surprised that the
supplied flash config is commented out and erroneous:
[FLASH]
;CHIPTYPE AM29F ;Flash type (AM29F | AM29BX8 | AM29BX16 | I28BX8 | I28BX16)
;CHIPSIZE 0x200000 ;The size of one flash chip in bytes (e.g. AM29F010 = 0x20000)
;BUSWIDTH 8 ;The width of the flash memory bus in bits (8 | 16 | 32 | 64)
;
Did you start with the Embedded Planet offering, in your current effort
to create a usable config? Is MIRRORX16 more than a guess?
I've found that my flash chips are "spansion GL256N10FFI02", which
AFAICT are S29GL256N10FFI02 from AMD, as we used to know them.
I wonder if S29M32X16 is a likely guess for CHIPTYPE on the card which
has landed in my lap?
Maybe the most important question is: Will a wrong algorithm choice let
the magic smoke out?
