MSP430FR2633: Software BSL Invocation with MSP-CAPT-FR2633 over I2C

Part Number:MSP430FR2633

Should we able to SW invoke I2C BSL with MSP-CAPT-FR2633?

HW invoke seems to work fine https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/599242

(though how are they connecting to the TST pin on the EVM?  Don't see it going to a jumper.  Only a connector.  Is it OK to tie TST low?)

And using the following SW invoke code, I can see connected with CCS that I am in the BSL

__disable_interrupt(); // disable interrupts ((void (*)())0x1000)(); // jump to BSL

But seem to be stuck in a &USCI_A0__UART_Mode_UCA0IFG test loop.

Do we need to do something special to get to I2C BSL?  Are we stucj in UART BSL?  Do we have to HW invoke to get I2C?
