Part Number: MSP430I2020
Other Parts Discussed in Thread: CC2650

Hi Team,

As MSP430i2020 does not support BSL so we are unable to program over UART same like CC2650.

So can we plan like below mentioned thing.

CC2650 and MSP430i2020 can be interfaced over Spy-Bi wire and through CC2650 we will program the MSP430i2020. Can we do like this? And is there any reference for development like this?

I want to do this because in production i want to use single UART to flash CC2650 and MSP430i2020 so by doing the above thing we will have only UART for flashing the code in both.

Hi Sumit,

Sure, you can program the MSP430 device by a host processor via Spy-Bi-Wire. Please find the implementation guide here: MSP430 Programming With the JTAG Interface (Rev. Z)

Hi Wei,

Thanks for confirmation and techcial document. As per my understanding we can also make our BSL for MSP430i202.
Can you please share technical document for MSP430i2020 for BSL development reference.

Hi Wei,

Thanks for document. May i know this is general document for all MSP430 series or this is specially only for some specific MSP430.
I am planning to write CUSTOM BSL for MSP430i2020, so please confirm for that.

It should be the common document for MSP BSL.

Hi Sumit,

you can refer to Custom BSL430 package. This is the latest release of it: download link.

After you download the package, the source code is located under 5xx_6xx_BSL_Source. There are some basics example for different BSL that uses different module as peripheral: UART, I2C, and Timer A. The project are based on IAR MSP430 IDE.

For the reading-material, you can refer to SLAA450.

Let me know if you need further assist.
