I have a Pix32v5 system with DShot ESCs. I have configured the DSHOT_TEL_CFG parameter to use TELEM3. However, after system restart, the telemetry is not started:
nsh> dshot esc_info -m 1
ERROR [dshot] Telemetry is not enabled, but required to get ESC info
I have to manually start it, to get access to the esc telemetry data:
nsh> dshot telemetry /dev/ttyS4
nsh> dshot esc_info -m 1
INFO [dshot] ESC Type: #Furling32_A#
INFO [dshot] MCU Serial Number: d14642-353638-100030-4d5057

Any clue where to look for the reason for this behavior?
I’m using 1.12.3 stable. No suspect messages in the dmesg log. I have tried to change the port, and it works (on a different free port), or I get a message about a conflicting port usage (on an already used port). I will post the output from the debug console once I have it.
Here’s output of the debug console. I print all DSHOT* parameters at the bottom:
