MSP430FR50431: MSP430FR50431 - burn by using MSP-FET

Part Number: MSP430FR50431
Other Parts Discussed in Thread: MSP-FET

Hi,

I have a custom board that contain the msp50431, and i use the MSP-FET to burn into it a new code.

I connect the pins according to your recommendation:

When I try to do this the first few times all the pins look normal but after 2-3 times I see that the reset leg is stuck on 0 and I try to go to 1 but it is stuck.
I am attaching the scheme- could it be that resistor R19 is too large and therefore fails to rise to VDD?
If you can think of other logical reasons, I would like to know because I have reached a situation where I can no longer burn the component - because the CCS does not recognize it.
