[U-Boot-Users] tftpboot question
I'm trying to use tftpboot to copy linux image into flash starting address is 0xff300000, so I defined CFG_DIRECT_FLASH_TFTP. It looks data have been written into flash since there is no any error. However, when I try to boot linux, it returns gunzip error. If I download the same image using xmodem, the kernel just boots fine. Do I need to do anything special for tftp direct to flash? If I tftp image into ram(0x800000) then boot, it's just fine too.

Why are you doing this? The recommended method is to load the image to RAM first, and then use "cp" to write it to flash.
written into flash since there is no any error. However, when I try to boot
Did you use the "iminfo" command after writing the image tpo flash? What does it say?
linux, it returns gunzip error. If I download the same image using xmodem, the kernel just boots fine. Do I need to do anything special for tftp direct to flash? If I tftp image into ram(0x800000) then boot, it's just fine too.

This does not look like normal "bootm" command output to me. Are you sure your image was started by a bootm command? And are you sure it is an uImage file in the first place?
To me this looks as if you were using the Linux kernel's bootstrap loader, which you must not do.

This is NOT an U-Boot error message.
