Hi all, I’m trying to boot the orin board into lock/hybrid mode as it is using ARM A78AE CPUs. According to my previous question Enable Dual-core Lock Step for ARM CPU on Orin chips and the updated adaption manual, what I’m supposed to do is two things.
First, I need to modify the device tree node of c7 cpu idle state. Which I have successfully done it, and the system is able to boot after this. This would result in 4 cpus offline. I attach screenshot from my de-compiled
tegra234-p3701-0000-p3737-0000.dtb file and my screen shot of
However, the second step which is to modify the
tegra234-mb1-bct-misc-common.dtsi make things go wrong. Whenever I change the field of
num_clusters_2core_pair_lockstep, it goes wrong. If I change it to 0x1 or 0x2, it will not be able to flash. If I change it to 0x3 as implied by another question, I can flash but not be able to boot. The fan is also not working and the board becomes overheat really soon.
Can anyone help on this? Does anyone successfully boot the board in lock mode? How does it look like in lscpu and htop?
