Re: [Libreboot] blank screen with libreboot on x200

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.
