I'd also like to jump into this thread. I recently wrapped up a project using a TE0715-05 and a custom carrier board where everything was handled in QSPI (no SD card was present). I am now working on getting the same functionality for a few TE0715-04 boards I have, but am struggling to get them to do anything. I followed the same steps for the 04 as I did with the 05, and it says they are being programmed successfully, but the boards do not boot, and there isn't even a boot menu I can get into on startup.
Is there a pin I should be setting or any ideas?
Thanks
