Debugging

[Ejh4286]

I’ve noticed some EFIs produce a text file that is useful for debugging. Can anyone tell me howbto turn this on? Thanks.

Add

-v

to the boot-args

I am familiar with verbose mode. What I am looking for is the feature that actually writes a text file to the root of EFI partition.

That is only useful if the error is from within OpenCore. You need to download the DEBUG version not RELEASE and set the Target in the config to 67.

I have two Asrock trx40 boards, one with the 3960 cpu, one with the 3970 cpu. The 3960 boots into monterey no problem. I took that efi, adjusted the core count in the kernel patches and used it in the 3970 machine. It starts to boot (in verbose mode), and i get a kernel panic and i see IONnvme controller before it reboots. Its very brief so i cant get a picture of it before it reboots. I’ve tried several different ssds same result. I’m trying to gather more info so those who know more than I can hopefully diagnose.

Did you change the core count patch for the 3970 machine? You need to change it from 32 core to 64 core. The hex you need is 40 for the 64 core.

If you add the keepsyms=1 and debug=0x100 boot arguments to your config.plist the Verbose text should remain on the screen, and the system not automatically reboot.

You could also try videoing the verbose text and then step through the resulting video to see what is being generated before the reboot.

I used 20 in the core count since the 3970 is 32 core. Are you saying I should use 40?

Ohh wait no I looked at the threads Don't use 40. Are the boards the exact same? If not and you've set some MMIO like most TRX40 users do you'll need to redo that. You can also record the screen and playback in slow to catch the panic.

They are both Asrock Trx40 Creator boards, same bios version 1.70. I've attached my EFI and a screenshot of the verbose mode output during the kernel panic.

Give this a go. If it still panics it should be easier to see it.
