Other Parts Discussed in Thread: UNIFLASH
I am attempting to setup the SK-AM64B EVM, and I am following the EVM Setup instructions under the AM64x MCU+ SDK. Under Flash SOC Initialization Binary. it states that a C character should be printed out every 2-3 seconds. In my setup I am seeing random characters (shown below).
I initially ignored this, but I am running into issues downstream when I try to run the commands to flash the SOC initialization binary to the device. Here's what I am getting:

Some assistance with this would be greatly appreciated.
