U-Boot tegra-l4t-r32.7.6_good detects new module as 2GB:

U-Boot 2020.04-00005-ge5ea88b0bc (Dec 14 2024 - 18:46:43 +0800)

SoC: tegra210

Checking the hardware-nvidia-platform-t210-porg.patch patch provided in 32.7.5 overlay, tegra210-porg-p3448-emc-a00.dtsi in 32.7.6 is still missing the table for nvidia,ram-code = <1>. I need to load an overlay to include that section to boot the kernel:

Also, for some reason, we only got 2GB memory usable in the system as well.

please apply the overlay file on this website.

I’m already on 32.7.6 and I expect it to support this already, or it would have the same overlay downloads like 32.7.5.

5

the overlay for 32.7.5 is same to 32.7.6. You could apply it directly to 32.7.6.

32.7.6 was released in 2024-11, the overlay was released in 2024-08. I think this is a major oversight for not including it in the final release of L4T R32.

I’ll open another thread if the overlay didn’t solve the memory issue. Right now I only added the missing EMC table in the overlay patch, but not the other blobs.
