在配置u-boot 我的nand flash 和 sdram 分别是
K4S281632K-UC60.pdf
K9GAG08U0M.pdf
需要配置的参数是[这是样例]
[SDRAM]
BUSWIDTH 16 ;The bus width of the SDRAM in bits (16|32)
BANKS 4 ;The bank number (2|4)
ROWADDR 12 ;Row address width in bits (11-13)
COLADDR 9 ;Column address width in bits (8-12)
ISMOBILE 0 ;Define whether SDRAM is mobile SDRAM, this only valid for Jz4750 ,1:yes 0:no
ISBUSSHARE 1 ;Define whether SDRAM bus share with NAND 1:shared 0:unshared
[NAND]
BUSWIDTH 8 ;The width of the NAND flash chip in bits (8|16|32)
ROWCYCLES 3 ;The row address cycles (2|3)
PAGESIZE 4096 ;The page size of the NAND chip in bytes(512|2048|4096)
PAGEPERBLOCK 128 ;The page number per block
FORCEERASE 1 ;The force to erase flag (0|1)
OOBSIZE 128 ;oob size in byte
ECCPOS 24 ;Specify the ECC offset inside the oob data (0-[oobsize-1])
BADBLACKPOS 0 ;Specify the badblock flag offset inside the oob (0-[oobsize-1])
BADBLACKPAGE 127 ;Specify the page number of badblock flag inside a block(0-[PAGEPERBLOCK-1])
PLANENUM 1 ;The planes number of target nand flash
BCHBIT 4 ;Specify the hardware BCH algorithm for 4750 (4|8)
WPPIN 0 ;Specify the write protect pin number
BLOCKPERCHIP 0 ;Specify the block number per chip,0 means ignore
请教大家这个怎么配置，最好授我以渔，谢谢！ |
