Enable ramoops on Xavier Industrial

How to enable ramoops for the NVIDIA Jetson AGX Xavier industrial? Ramoops works for the JAX, but for the JAXi it doesn’t work. Is there a reason behind this?

I saw that the JAX configures the memory during the flashing script with:

carveout.ramoops.size = 0x00200000; #2MB
carveout.ramoops.alignment = 0x00200000; #2MB

but this doesn’t work for the JAXi, as it crashes when these rows are added to tegra194-mb1-bct-misc-l4t-jaxi.cfg

I also saw that nvramoops.sh checks if the model is not a “Jetson-AGXi”, if not, it executes “modprobe ramoops”.

Is there another way to configure the required memory for ramoops and to get ramoops working for the JAXi?

Hi
JAXi has DRAM ECC enabled. As a result, the scrubbing is done on boot. And ram content is lost

thanks

Is it possible to disable DRAM ECC for the JAXi? So Ramoops can be used during development
