Clouds - Initial Programming

Good Day to you all.

I have just finished building Clouds and have flashed it with the bootloader and firmware. Is there anything else required (resourcefile?) as when switched on the module, it does not respond and has the 4 yellow LED’s on permanently? Voltages and current drawn are correct and the software install verifies OK (I use STMCubeInstaller).

Thanks,

Karl
