Help with kernel flasher
 

I'm totally new at this, and searched for some help... but no luck.

I am trying to use the kernel_flasher to install the support for high speed MMC cards and fixes. I have my 770 in red-pill mode (not sure if that's necessary), have root access, and am trying to run "sh kernel_flash zImage-48MHz" from "media/mmc1/kernel_flasher".

I am getting a series of errors:
./xxd: Permision denied
expr: syntax error
expr: syntax error
expr: syntax error
expr: syntax error
This is not a valid kernel image, cowardly exiting.

Can someone point me in the right direction?

Thanks.

Flashing has to be done from a desktop. You didn't actually think you could overwrite a running kernel with another one, did you? :p

extract flasher directly to internal flash, do not run it from mmc, do not use 'sh ..'
just something like

You can. Kernel is unzipped to RAM at boot time, kernel flash partition sits unused while it runs.

Actually the kernel flasher is 'safer' than initfs flasher. Initfs partition is rewritten while it is mounted and dsme and bme run from it.

Thanks, that did the trick!

Thanks also for this great kernel update. Now I can transfer large files to my 770 using WiFi or USB without it rebooting after a few minutes. Not to mention the fact that the transfer rate is now well over 4X what it used to be.
