BTT TFT35 E3 V3.0.1 firmware update problem

All,

On my LR3 I am using a BTT TFT35 E3 V3.0.1 touchscreen connected to a SKR Pro 1.2.

For a couple of days now I‘ve tried to flash my TFT screen with no success. The V1 pre-compiled firmware from the repo flashes ok as does the original BTT firmware. Both *.bin files renamed to *.cur after the update.

But when I compile the corresponding sources with VS Code and PlatformIO, the resulting *.bin files will not be flashed by the TFT controller. The sources are all from the same Github repository where the pre-compiled *.bin came from. I did not change the sources nor did I change any config file. I’m getting a warning though: ‘Warning! Cannot find the default startup file for stm32f207vct6. Ignore this warning if the startup code is part of your project.’ which I am inclined to ignore as - again - these ar the original sources from BTT/V1.

I‘ve compiled on different machines now, changed the SD card, formatted with FAT - with no success.

Maybe I’m not seeing the wood for the trees anymore, so any idea would be greatly appreciated!

Thanks, Christian
