[U-Boot] Need Help on *** Warning - bad CRC, using default environmen​t

[Bala Ss]

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".

Regards,
Balaji.

It might help if you specified which version of U-Boot you run and for 
which board it is built.

Note that if you're not using the mainline U-Boot but a custom vendor 
one, you should inquire with the vendor.

Note also that if you're using the mainline U-Boot, then you should make 
sure you're using the latest version.

I think that your Environment is in NAND, and as there is
no NAND, u-boot couldn;t find an environemnt ...

Please send the u-bot version and on which board you use, so we maybe
can help you!

Heiko

Hm... Did you try google?

If you search for "Warning - bad CRC, using default environment"
google will show the relevant entry in our FAQ as the very first hit.

It's really quite difficult to miss that, and I kind of admire how you
manage to do that.

As Albert already wrote: without any information about CPU type,
board name, origin and version of the U-Boot code you are using it is
impossible to answer this question.

Hello Albert Aribaud,

Thanks for your reply.

The board contains LSI ARM processor and the U-boot is customised for the
same.

Regards,
Balaji.
