大家好！我在烧写uboot时遇到了校验错误，信息如下：

平台信息如下：
Platform: dm8168 ccs5.2
Emulator: xds100v2
Flash: k9f2g08u0m
File: nand-flash-writer.out
Uboot file: uboot_NAND_DM816X_DVR
Nand flash details是正确的，dm8168的datasheet中支持device ID=0xda的设备。但我不能确定k9f2g08u0m是否支持BCH 8bit，datasheet中只有这一句：
ECC : Error Correcting Code --> Hamming Code etc.
Example) 1bit correction & 2bit detection
我试过ECC选择2（HAM，好像不支持）, 烧写时不报错，但重新上电后平台无法启动，串口没有任何打印信息。我在e2e上看到了同样的问题，但没有好的解决方法。请大家给点建议，谢谢！
