External PA not working.

[esoft.1]

Dear sir

It is being developed on the ST25ru3993 board. The external PA is not working, so I checked the power and it is 0V. The documentation says it should be 4.1V, but I want to know if I can make it work again.

Also, I want to know why the expansion PA is not powered.

​

If I configure another external PA circuit and use it, I wonder if I can operate it with that board.

​

If this is possible, I would like a circuit recommendation.

​

Thank you, sir

Dear esoft.1,

please could describe, which software are you using?

Is it an own software or do you use the ST software for controlling the board?

Thanks & best regards,

Marcel
