Bad Data Crc Error

11:50:11 Hi,,, I have burned u-boot, uImage and qtopia_64M in my nand. While booting, it shows me this and gets stuck at the end saying. Bad Data CRC. ERROR: can't get kernel image! This is the output on minicom. Please let me know the solution to this problem.

Is that all you see while it is booting up? The full boot message down to the first error might be more helpful. Dhruv Vyas 2012-05-30 12:18:34 I made my own kernel image using arm-linux-gnuebi toolchain using standard procedure,as far as u-boot and qtopia are concerned, they are from DVD. Kernel image used to work fine with NFS server using u-boot. However, It throws me this error when I try to get it booted from NAND. And ya....it is the only thing I get. It stops there giving me "u-boot" prompt. Dhruv Vyas 2012-05-30 12:20:05 I think it is because u-boot does not have bbt. How to create BBT without erasing NAND blocks ? davef 2012-05-30 12:44:30 So, you managed to get u-boot to load your kernel and root filesystem using NFS? I only ever used u-boot to load stuff into NAND and part of that task involved . This took care of the BBT issue. Could you reference the tutorial you used or state your procedure to get u-boot to do: nand scrub mtdparts dynenv set etc. when using NFS. I would like to understand how you managed to do that. Which toolchain did you use to make you own kernel? One issue is that there is limit around 2+M where you ha

get kernel image! Messages sorted by: [ date http://lists.denx.de/pipermail/u-boot/2010-April/070102.html ] [ thread ] [ subject ] [ author ] I am using u-boot version 2009-08 for customized PPC 440 based board. https://archlinuxarm.org/forum/viewtopic.php?f=46&t=6344 Board is having 16MB Nor flash. I am flashing the kernel image at 0xffdc0000, ramdisk at 0xff8c0000 and dtb at 0xff200000 When bad data I pass bootm command through u-boot prompt i.e "bootm 0xffdc0000 0xff8c0000 0xff200000" Kernel booting stops with following error message. ## Booting kernel from Legacy Image at ffdc0000 ...
