I have problems with the blackbox on a Mobula 7 1S HD.

It has a separate blackbox, type OpenLager via serial.

In the Betaflight configurator it shows "No dataflash chip found" but everything is configured according to the instructions.
It is not possible to change the parameters under the blackbox tab, it must be done via the CLI. A bit like it only semi recognizes the module.
When I then do a testflight (several), files are actually written to the SD card (32GB PNY, FAT32). 
One "LAGER.CFG" with some parameters and then a number of "LOG001", "LOG002" etc.
But these are completely empty.

Very grateful if anyone has an idea that can give me a push in the right direction to maybe be able to solve this?

For openlager you have to be sure the baudrate is set high enough. Mob7HD should be on UART1 and you can type this command into your CLI => serial 0 128 115200 57600 0 2000000 and save. Be sure you have selected SERIAL PORT under blackbox device.
