如题,拿到一块jz4740的板子,配置如下
nand HYNIX HY27UU08AG5M-TPCB 834H (HY27UH08AG5M)?
sdram ELPLDA EDS1232AATA-75-E
cpu JZ4732/JZ4740
用君正usbboot1.4进行操作,总是提示Configure fail!
配置文件按照sdram和nand的pdf进行配置的,应该不会有错啊
可是就是不对,无法启动,也不能进行烧写nand等操作
Checking state of No.0 device: Unboot
Now booting No.0 device:
Download stage one program and execute at 0x80002000: Pass
Download stage two program and execute at 0x80c00000: Pass
Boot success!
Now configure No.0 device:
Device unboot! Boot it first!
Configure fail!
上面说启动成功,然后又说我因为没启动所以失败...我都汗了...
memtest和gpio等不需要boot就能执行的操作提示成功,但不知道到底成功没有
cfg配置文件如下
[PLL]
EXTCLK 12 ;Define the external crystal in MHz
CPUSPEED 336 ;Define the PLL output frequency
PHMDIV 3 ;Define the frequency divider ratio of PLL=CCLK:PCLK=HCLK=MCLK
BOUDRATE 57600 ;Define the uart boudrate
USEUART 0 ;Use which uart, 0/1 for jz4740,0/1/2/3 for jz4750
[SDRAM]
BUSWIDTH 32 ;The bus width of the SDRAM in bits (16|32)
BANKS 4 ;The bank number (2|4)
ROWADDR 11 ;Row address width in bits (11-13)
COLADDR 7 ;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 2 ;The row address cycles (2|3)
PAGESIZE 2048 ;The page size of the NAND chip in bytes(512|2048|4096)
PAGEPERBLOCK 64 ;The page number per block
FORCEERASE 1 ;The force to erase flag (0|1)
OOBSIZE 128 ;oob size in byte
ECCPOS 28 ;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 2 ;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
[END]
急需解决,有谁遇到这个问题解决过么,我都搞了好几天了./...疯了 |
