当我尝试将uImage下载到电路板时，我收到CRC错误，
Bytes transferred = 10543306 (a0e0ca hex)
## Booting kernel from Legacy Image at 01000000 ...

这是我使用printenv命令：
printenv

filesize = a0e0ca = 10543306，与笔记本电脑中的图片尺寸完全相同。
另请注意，我昨天成功下载了一张图片。
在uBoot中是否有配置像开始地址或像这样的sthing，或者我可以说闪存已损坏
我用：
BF609板
Blackfin的buildroot的-2013R1-RC2
tftp服务器
