I would like to use DFU to upgrade the factory image. My firmware is based on the USB audio 6.15.2, but does include custom DSP (not running on USB tile). Using OSX terminal and following the instructions carefully, I can successfully create the firmware upgrade .bin file. Then I execute the following, however it just hangs on the last ...Download image line:
Code: Select all
bash-3.2$ ./xmosdfu --download firmware_upgrade.bin
