Hi all

I cannot program 1321x SRB board by a BDM programmer when I use switching power supply (yellow led on programmer is OFF). But when I use USB supply it can be programmed (yellow led on programmer is ON). I have the same problem when programming 13192 SARD board whith switching power supply. Unfortunately the board has no USB connector. So I cannot program the board at all. 

I measured switching power supply voltage with voltmeter. It is 9.15volt.

 

Thanks
