I am developing a high volume FRAM programming solution for A GM Ventilator controller. I cannot get the JTAG to respond for device type MSP430FR5949. I have the sample in a socket adapter that works fine for device type MSP430FR5725RHA. The two devices have identical pin functions except for pin 30 that should not matter.
If am wondering if there are any other pins required to wake up the JTAG or something that is keep the JTAG from responding on the MSP430FR594.
It seems that the TDO just stays Hi-Z.
Once again this is for a GM Ventilator controller, so my need for technical help is rather urgent.
