Other Parts Discussed in Thread: SK-AM62A-LP
Hello,
I'm trying to measure power by following below URL.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1273364/faq-sk-am62-how-do-i-measure-power-and-temperature-on-the-am62a-and-the-am62x
I could observe expected result on SK-AM62A-LP, but I could not get expected result on SK-AM62X.
When I run script on SK-AM62X, I got following message, so it seems that AM62X could not communicatte INA device correctly.
