Is there an available DRAM config to support L4T 35.6.2 for Orin Nanos with the change referenced in PCN212822? There is nothing referencing that JetPack version (5.1.5) on the PCN download center. Flashing using the meta-tegra yocto layer using packages from L4T 35.6.2 shows a RCMBoot failure with serial logs showing:

Based on the provided context, it appears that you are looking for a DRAM configuration that supports L4T 3562 for Jetson Orin Nanos, specifically with the changes referenced in PCN212822.

From the context, we can see that there are two Jetson Orin Nano modules:

  1. Jetson Orin Nano 4GB-DRAM (P3767-0004) - Production
  2. Jetson Orin Nano 8GB-DRAM (P3767-0005) - Development

Both of these modules use the Jetson Orin Nano reference carrier board (P3768-0000) and support flashing QSPI-NOR and USB/NVMe drive (only supported via l4t_initrd_flash.sh) or microSD Card/USB/NVMe drive (only supported via l4t_initrd_flash.sh).

However, there is no explicit mention of L4T 3562 or PCN212822 in the provided context. It is also unclear whether the changes referenced in PCN212822 are specific to a particular DRAM configuration.

That being said, if we compare the two Jetson Orin Nano modules, we can see that the main difference is the amount of DRAM (4GB vs 8GB). If you are experiencing issues with flashing using the metategra yocto layer and packages from L4T 3562, it’s possible that the issue is related to the DRAM configuration.

To resolve the issue, you may want to try the following:

  1. Verify that you are using the correct DRAM configuration for your Jetson Orin Nano module.
  2. Check the PCN download center for any updates or patches related to PCN212822 and L4T 3562.
  3. Try flashing using a different method, such as the NVIDIA SDK Manager or the l4t_initrd_flash.sh script.
  4. If you are still experiencing issues, you may want to consider reaching out to NVIDIA support for further assistance.

In summary, while there is no explicit mention of L4T 3562 or PCN212822 in the provided context, it’s possible that the issue is related to the DRAM configuration. By verifying the correct DRAM configuration and trying alternative flashing methods, you may be able to resolve the issue.

This response could be improved.

However, there is no explicit mention of L4T 3562 or PCN212822 in the provided context.

That’s in the first line of text I posted. Seems like it got confused about my reference to production vs samples. In this case I am using a Production module, but have access to a sample unit with the changes that are noted in the PCN referenced.

The overlay patch for PCN212822 hasn’t be provided in download center yet. it will be released soon.
