Possible way to change the os baudrate?

[MNS26]

I have been tinkering with the uboot_defconfig, pine64_ox64_defconfig/pine64_ox64_full_defconfig but just cant get a terminal to propperly show up.

is there a way to have it be at 115200 for example?
i was only able to flash the boot chip because i have a pico, but for some reason the 2nd tty port it has doesnt seem to work.

(used default config for picture)

Looking at M0 output in your screen, D0/linux isn’t booted at all. (The SD card interupts count isn’t incrementing).

Check your flashing address/groups.

What USB2UART adapter are you using for D0 output? What pins are you hooked upto?

A rp2040 as a picoprobe. Its the only one i have that does 2M baud
GP14/15 for ttyACM0 and GP16/17 for ttyACM1

i forced uboot to have a baud of 115200 and then it is showing text.
i useda a Prolific Technology, Inc. PL2303 Serial Port / Mobile Action MA-8910P i bought from waveshare, sadly that one can only go up to 1.2M baud

hmmm.... left is running on ttyACM0 at 2M baud, upper right is running on ttyUSB0 at 115200, lower right is running on ttyACM1 at 2M

im absolutely lost to how its still able to even read ttyACM1 at 2M when the output is at 115.2K

i got it working.
i had to swap the serial port that connected to the serial port 0 and 1 on the picoprobe (swapped the wires)

EDIT:
after editing the boot config i fixed my issue
but i can only get text to appear when going through the 2M baud window (it doesnt display anything in that window)

got it working (yay).
had to lower the linux console to 115200 in the boot config to get it working (although i cant write at 115200 baud)

nvm ran into another issue... i cant send character at any other baud rate than 2M

nvm... i had HW flowcontroll on...
