This is using the same DSP board that was identified as faulty in this post: New tab (ti.com). As TI and Mouser are no longer carrying this board I'm trying to find if there is a way to use the board and thought perhaps using a different boot method may circumvent the issue from the other post. I have several questions related to alternate boot methods.
1) I may have missed directions on how to use the other boot methods available on the DSP board, is there documentation you can provide from the USB, eMMC, & UART boot methods?
2) I couldn't connect to the board from MMWave Studio with the DIP switch on the DSP board set to eMMC (111000). Is there setup that needs to happen for the board to boot from eMMC, or is this indicative of an error?
3) The attached text file is taken from the start of the boot sequence of the DSP board. After the last line in the file (starting kernal) the system has a few failure messages and I can add those in a comment if requested, but for the most part the system reports normal booting. Are the errors in the attachment normal give I am booting using the SD card or is this due to an error?
