Or if they can dump their mtd0 (which include the envs), then you can also flash the whole mtd0 file at once.

Hey,

Many thanks for your advice. Honestly I think the best options is ask for a dump, because I don’t know what I can check to figure out why the console is not working.

Perhaps I need to go to the orignal WD firmware?

I will try to contact CyperPK or vzhilov and let’s see if they can dump their u-boot.

Thanks again for all your time and advices with my issue.

Best

i5Js,

No, because the envs will not work.

Yes. Come back and I'll help you flashing it. It is best to have the dump for the entire mtd0 (5MB).

My pleasure, too bad serial console does not work, or we could have solved it many days ago!

I was meaning to get the WD firm back to get the console enable.. because it’s very strange that it doesn’t work at all. I was thinking it was because of the firmware and the chance it had not enable by default

Yes, it does not hurt to do that. But the chance is quite slim that was the reason. When the BootROM starts, u-boot is not running yet. The first few lines on console are from BootROM.

As expected, flashing the latest stock firmware didn’t fix or enable the uart :)

PM the users on that working thread for mtd0 dump. They might not read new posts.
