a few basic questions about a board i don't have access to right
this minute but did yesterday and will later today. it's an AM1808
experimenter kit lookalike except that it has (allegedly) had its NOR
flash replaced with 2G of NAND flash, and i want to figure out what i
can add to the current u-boot da850evm configuration to let me poke
around and get all the info i can on that flash because there seems
to be something strange about the current setup.
first, when i let the board boot fully into linux, "dmesg" told me
this:
"NAND device: Manufacturer ID: 0x2c, Chip ID: 0xdc (Micron NAND
512MiB 3,3V 8-bit)"
that appears to tell me 512M of NAND flash, not 2G. i asked
someone who was initially adamant that there was 2G but promised to
check with the H/W folks to make absolutely sure. is there a
possible reason why 2G would show up only as 512M in dmesg? (not
really a u-boot question, just wondering.)
Is it possible you have 4 chips, each of which are 512 MiB?
false alarm ... i got bad initial info and the board really does have
exactly 512M of NAND. whew ... wasn't looking forward to trying
to debug that.
