[U-Boot] "Verifying Checksum ... Bad Data CRC" when kernel

Hi all

I've found the answer and confirmed it. FTP transfer corrupted uImage.

As my development laptop has no COM port, I transferred uImage from this development laptop to my company's FTP server using FileZilla 3.0.11.1, then from this FTP server to my desktop using WS_FTP 9.01. Then, I used this uImage on my desktop for BOTH serial download and copying to SD card.

I don't know which, FileZilla or WS_FTP, corrupted uImage.

Now I use my thumb drive to do the transfer, kernel boots successfully for both serial download and SD card download.

Thanks & Regards, Zhao Jihua Embedded Systems Engineer
