EA8300, brand new, loaded the factory.bin, set the kernsize variable, and now it won't apparently boot correctly. the reason? i did fw_setenv kernsize=500000 with that stupid = sign in the middle. I can't make it swap to the other fw either. Is there a trick I've missed, or am I getting out my soldering iron and case opening tools?
Why did you do that? Changing this bootloader variable is only needed for installing a master snapshot.
Did that command bricked the router? It should have been ignored as the command needs two arguments. You only gave one: kernsize=500000. My guess is yes, you may nned to solder a serial console link and enter uboot maze.
I was just following the text, no idea what a master snapshot is, I just assumed it was required, as it is part of the section called 'Preparation for OEM GUI-Based Install', which is what i was doing. I would break that out into a separate section personally, although i'll put money on me being the only person inattentive enough to cock it up
However, good news for anyone as dumb as I was, I have managed to get to a working console by turning off flow control in my putty config. Reset the kernsize variable to 300000 (it was actually missing), SAVEd it and it now boots as intended. Thanks for pointing that out though, hopefully this post will stop others or help them if they follow me down this path
Good that you were able to recover.
You don't need to change the variable for simply running a stable 22.03. However you may consider changing in order to prepare your device for the future. It will continue to boot 22.03 and you won't notice anything.
Just don't make the mistake twice
