accessing the UART console on an MTK6765

[qwerty-in-me]

mktclinet has a meta mode for uart and since SPFlashtool can use it I'd like to use it directly to debug a bootloop I can't recover from, how can I do so?

since I use a Linux distro, UART over USB is inately supported by the kernel and so it should be straight forward to use it, but I couldn't find a single blog post, forum thread or article where that's done. Am I missing something or is there just no practical reason to even try?

as far as I'm aware, from powe on to LKs kexec there's a UART console for debugging purposes open and I should be able to just connect to it and yet I can't...

I'm on a similar issue, if some has a way to debug through UART console I'd be glad too ! :)

I'm facing the same issue for the same reason. I've tried an USB TTL with a wired usb c connector in the other end but that won't work.

Is there any way to boot the preloader and LK in a way that the log messages that are normally stored in memory to be printed over UART mode with mtkclient?
