ix4-200d scsi boot ext3 Bad Data CRC
June 30, 2018 08:11AM
First off USB boot works fine. I copied the ext3 rootfs partition from the USB drive to a sata disk. When I try to boot with the below setenv settings I get "Verifying Checksum ... Bad Data CRC" error when loading the kernel image "Linux-4.16.1-kirkwood-tld-1" Is there something I'm missing in the below setenv stuff? or should I try something else? I tried copying the partition twice. Thanks

This is the u-boot setenv stuff:
setenv hdd_make_boot_args 'setenv bootargs console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=orion_nand:$(uboot_size)@$(uboot_start)(uboot),$(env_size)@$(env_start)(env),$(kernel_size)@$(kernel_start)(zImage),$(initrd_size)@$(initrd_start)(initrd),32m@0x0(flash) earlyprintk=serial' 
setenv load_initrd 'ext2load scsi 0:2 0x2100000 /boot/uInitrd' 
setenv load_uimage 'ext2load scsi 0:2 0x40000 /boot/uImage' 
setenv hdd_boot 'scsi start; run load_uimage; run load_initrd; bootm 0x40000 0x2100000' 
setenv bootcmd 'run hdd_make_boot_args ; run hdd_boot; reset' 
boot


The bootlog of trying to boot the above is attached
The bootlog of USB boot is also attached

Please use code tags posting log.

The envs look OK.

Usually this CRCR error indicates that your rootfs is corrupted. You could post the log showing how you copied the rootfs from USB to HDD (copy/paste your terminal session), and I will doublecheck it for your.

I used GUI gparted on Ubuntu 18.04 to copy and paste the partition. I did the same copy paste from flash drive to flash drive and when pasted to a flash drive it boots without error. Could it be something with U-boot? It seems to load the images instantly from the sata hard drive vs the few seconds it takes from USB flash media. Next i will try a USB to sata adapter with the sata drive instead of the built in controller.

1. You need to be root while copying the rootfs. If you are not the root user, then the rootfs will not work. It really does not matter whether it boots.

2. Copying the partition like you did from USB to HDD is not the right way to clone the rootfs. See the Wiki thread for instruction:

Not u-boot. The CRC checksum error indicated that the image is corrupted.
