Tool/software:
Hi all,
We are using the J721EXCPXEVM with the J7200XSOMXEVM for our proyect development.
We are setting up the development environtment using the Processor SDK Linux for J7200 Version: 09_01_00 (which, as far as we know, is the latest version available).
We have followed the instructions provided by the Processor SDK documentation. However, we've reached a point where we're stuck—we are unable to load the kernel via TFTP.
To verify our setup, we repeated the same steps using a BeagleBone Black with the Processor SDK Linux for AM335X (Version:07_03_00_005), and we were able to successfully load the kernel via TFTP using the same procedure as with the J7200 SDK.
Given that, we're unsure why we’re not getting the same results with the J7200 SDK.
Below you can find how the EVM is connected, along with the logs from our attempts to load the kernel via TFTP.
The first log shows the attempt using the automatic boot script generated by the setup script (with a small modification to set static IP addresses instead of using DHCP). You can also see a ping test confirming that the board is on the network and can reach my host PC.

We're seeing a strange behavior during the kernel loading process. The output looks like this:

As mentioned in the SDK guide, we're using the MCU Ethernet port for this U-Boot configuration.
Do you have any idea what might be causing this issue, and how we can resolve it?
We would appreciate any help or suggestions you can provide.
