No logs
My own build is working with "Tiny_Blackbox" app. I can erase it via app (betaflight passtrough so serial connection is working with 500k baudrate acording to mode diagram) or thru button. But I cannot get any flight logs and usage is always 0.0%.
I configured UART1 as blackbox logging peripheral, also blackbox is serial port, 1/4 (800Hz as I'm using bmi270), GYRO_SCALED. Blackbox mode on aux4 and I see on OSD that it is working but no fast led flashing.
The rx/tx wires are twisted and as short as they can be. What else can I check?
Did you arm your quad? Betaflight sends blackbox data to serial only when it's armed. Is blackbox uart speed set to 1500000? (not 500000)
I can agree that the logging doesn't work with Betaflight 4.3 / 4.4 The last working Version is 4.2.11
With BF 4.3 /4.4 I can only read and erase the Blackbox over Betaflight Passthrough.
I tested on three different Targets and on all the behavior is the same.
For a quick Bench testing the blackbox on motor tab I can recommend to add:
set blackbox_mode = MOTOR_TEST
Logging starts when the motors test mode is active.
Same issue here, but I use recommended buad rate. Bench testing doesn't work for me. Blackbox over Betaflight Passthrough works fine, erase and read. But no fast blinking on arm. I use BF4.5
Sorry for delayed answer. I have reproduced this issue and now I started investigating it. Hope to come up with the solution soon.
@tchleb You can try 4.4.0. Logging works in that version. But it's weird why it doesn't on other versions

Already tried. I tested it with 4.4.0 and it didn't work reliably.
