J784S4XEVM: Which Processor configuration

Hi Takuma, 

Thanks for your response. I was under the impression that TDA4VH is the variant on this Eval board. Does it mean that there is a fifth variant that you listed: XJ784S4xAALY? Is there anyway I can see that through /proc file system when booting Linux or within uboot printenv?

That is my understanding. J784S4XEVM has the J784S4 superset processor.

Not to my knowledge. Let me route this to others on my team to see if they have knowledge.

Can you share the u-Boot logs?

Hi Keerthy, 

Do you want me to run specific commands on my uboot command line? Below is the output when it boots,

No such way in Linux. I am looping in HW expert.

Is XJ784S4xAALY the specific variant name?
