I have purchased a couple of AtomRC F405NAVI minis. It works mostly fine with the Atomrcf405navi fw (using tradheli). However the difference between the Navi and the mini is there is no SD card slot on the mini, so with 16mb of flash you’d think to use block to log. Nope, the fw isn’t configured to do that, so I have tried to compile my own fw by editing the hwdef.dat to remove the SD fs define, the remove the spidev entry for the SD card and add define HAL_LOGGING_DATAFLASH_ENABLED 1 to the dat file and compile in the hopes of having a function fw with logging to the onboard flash. The compiled fw has NO heli parameters at all and it doesn’t look like MavFTP sees the data flash block space. Any thoughts would be greatly appreciated.
