Hello, I tried the EHCI debug with the recommended beta x200 image. https://libreboot.org/beta/experimental-61-g03a48ed/rom/grub/libreboot_experimental-61-g03a48ed_grub_x200_8mb.tar.xz
I suspect it's not a screen issue, but a ram issue. I don't get any EHCI Debug output. With the kernel parameter "earlyprintk=dbgp,keep" and original bios I get the printk output so the beaglebone black setup is buggy but working. Are there any recommended parameters in order to debug ram issues? I have 4 ram modules of 4 types. I have read that libreboot should be able to use a single module.
