Other Parts Discussed in Thread: UNIFLASH, TMDS64EVM
I'm trying to follow the "Getting Started: EVM Setup" instructions from mcu_plus_sdk_am243x_08_05_00_24 using a TMDS243EVM board. I've configured the DIP switches for UART boot mode and confirmed the data from the first FTDI UART looks like the sample shown on power-up.
When I get to the next step, the uart_uniflash.py Python application fails during the second command. The first command that downloads the file via XMODEM always works OK. The second command (which programs something into OSPI?) always fails. Sometimes if fails at 0%, sometimes it gets to around 5%. Examples of both cases are shown below. I've tried both the am243x SDK and the am64x SDK (same version) and get the same results for both.
