Hi,
I have got this contact from web when I actually searching for some solutions to get rid off the issue on "Warning - bad CRC, using default environment". And I have gone through the some of the mail thread.
Am also facing the same issue that when I hard reset the board, U-boot starts and stops at line as below *** Warning - bad CRC, using default environment. From your mail thread conversation, its almost clear that this is due to uninitialization env variables / non-matching CRC, hence it needs to be "saveenv". But now the actual problem here is am not getting the U-boot prompt (#) to enter uboot commands. As soon as the board hard rebooted it comes and hangs at the same line, so not able to enter any commands there. If anyone can suggest anything that helps to bring up, will be really great. Thanks in advance.
Uboot-logs: =========== Flash: 16 MB NAND: No NAND device found!!! 0 MiB *** Warning - bad CRC, using default environment "Hangs".
