I erased the nand memory of an CC-IMX6UL SBC PRO, while trying to update the firmware using “nand erase.chip” so i tried to recover it as described in this page
Usb debug run without issue but the boot message on serial terminal show " *** Warning - bad CRC, using default environment "
if i ignore this and use run install_linux_fw_sd command to update the firmware using SD card, it install without error but it restart in recovery mode with this message
“Error reading superblock on volume ‘ubi0:recovery’ errno=-22!”.
if i update partitions manually using “update” it does not boot on recovery mode but still get the same message except volume linux.
Am assuming the partition table is missed-up but not sure how to fix it. And what am doing wrong to get the CRC error with USB Debug. I tried various .imx files version 2.0, 2.2 and 2.4 same error.
