Part Number: MSP430F6436

Hello,

I would like to update the firmware using UART based on USCI peripheral.

But when using BSL, I found P1.1 and P1.2 which is not UART port is used.

Could you tell me how to update the firmware using UART based on USCI peripheral?

Is it possible by custom BSL?

Could you tell me how to implement custom BSL firmware which can update programs using USCI UART?

Regards,

Hi Gary Gao,

Thank you for your reply.

I would like to firmware update using not P1.1(BSL TX), P1.2(BSL RX) but such P8.2(USCI UART TXD), P8.3(USCI UART RXD) in MSP430F6436.

Is it possible by using custom BSL?

Could you tell me how to customize BSL in order to update firmware using USCI UART pins?

Regards,

U-SK

I have a transition guide for FRAM devices here (The modification detail is different, but the step is the same) You can have a look3056.Porting_guide.pdf
