Dear team,

My customer used 2 UARTs(eUSCI_A0 , eUSCI_A1 ) of MSP430FR6972. Now they want to use UART BSL.

Please kindly tell me how to realize this function?

Hi Susan,

If you look at section 6.5 of the datasheet, you'll see that four pins are required to use the UART BSL. You'll need RST and TEST in addition to Tx and Rx for the entry sequence. If the customer wants to do something custom, you'll need to refer to Step 3 on this page:
