Beaglebone外围电路ee_fpga_cape调试记录(4) - 继续NAND [复制链接]

苦逼的的U-boot 2011.09 居然不知道4GB的nandfalsh，现在已调试为主，暂时不搞移植了，迫于无奈，换了个256MB的nand

U-BOOT终于识别了：

1. U-Boot 2011.09 (Nov 04 2011 - 21:39:19)
   
2. 
   
3. I2C:   ready
   
4. DRAM:  256 MiB
   
5. WARNING: Caches not enabled
   
6. No daughter card present
   
7. NAND:  HW ECC Hamming Code selected
   
8. 256 MiB
   
9. MMC:   OMAP SD/MMC: 0
   
10. *** Warning - bad CRC, using default environment

linux同样识别，也没有那么多警告了

1. [    0.885371]  omap_hsmmc.0: alias fck already exists

3. Device 0: nand0, sector size 128 KiB
   
4. U-Boot# nand erase.chip
   
5. 
   
6. NAND erase.chip: device 0 whole chip
   
7. Skipping bad block at  0x03e00000
