Hello,
I am using the MSP430FR2476 on a custom PCB and I am trying to flash it using the debugger portion of the LP-MSP430FR2476, but I get an "Unknown Device" error in CCS when doing this. I have the SBWTCK, SBWTDIO, RX, TX, and VCCTARGET (3V3) from the Launchpad headers connected to the corresponding pins on the custom PCB, this is basically what the Launchpad does with a few jumpers. This process worked when I tried programming the MSP430 from another Launchpad (Launchpad 2) using the programmer from Launchpad 1 (the Launchpad I am using now).
I have verified that the signals arrive on the MSP430 pins on the custom PCB and I have attached a screenshot of these signals. The TX and RX signals did not change so they are not included in the screenshot.
I have tried powering the MSP430 using both the 3V3 line from the debugger and an external 3V3 power supply with no change.
I have also supplied the schematic of the MSP430 in the custom PCB I am building. It is basically the same as the Launchpad without the LEDs and the external oscillator.
Thanks in advance for any help.
