Thanks!! While figuring out where/how to drop this defconfig in the TI SDK's directory structure, and have it override existing kernel configuration settings, I'm thinking of trying something in "parallel."
Since the stock BeagleBoard-X15 SD card image booted Debian on my 57XX EVM (but with some pru/remoteproc errors), I'm wondering if I can still use the 572X EVM with the BeagleBoard-X15 SDK image (kernel and all), to move forward with installing Mono/.Net with RS232/serial port (over USB) + Ethernet access. I don't know whether the USB ports on the EVM are 2.0 or 3.0, but if they're < 3.0, then they should work, right? Thanks again!!
