求助，北极星pro-q5 升级后固件损坏

北极星pro-q5 通过wifi升级后状态灯常亮，用ttl线连接到看到uboot提示“Verifying Checksum ... Bad Data CRC”，可以怎样搞？
整个过程如下：

Please choose the operation:
   1: Load system code to SDRAM via TFTP.
   2: Load system code then write to Flash via TFTP.
   3: Boot system code via Flash (default).
   4: Entr boot command line interface.
   7: Load Boot Loader code then write to Flash via Serial.
   9: Load Boot Loader code then write to Flash via TFTP.

3: System Boot system code via Flash.

CRC校验出错，不知道错在哪里。可能是固件不对。

我从北极星下载固件，再用tftp的形式刷上去，这样做能凑效么?

自己搞掂了，要找一只相同型号的机器，用编程器克隆spi芯片，再重新写入，就可以解决了。用ttl线试了很久都搞不定。
