preenfm2 and preenfm3 / Will PreenFM2 boot without the DAC?
« on: October 25, 2020, 03:51:01 AM »
Hi all. I'm building PreenFM2 from odd parts around the workshop and have the firmware flashed onto an old dev board which I've swapped the F405 onto. It's not booting past the bootloader though - wondering if it's due to not having the DAC connected yet. The 74hc165s are connected and appear to be working. I can navigate and have the firmware flashed again from a connected USB stick. If it should boot without the DAC I'd like to troubleshoot before building the DAC and output section.
Thanks!
Thanks!
