Other Parts Discussed in Thread: MSPM0G3507

Hi Team,

Posting on behalf of our customer.

I'm trying to use this example to doing fw update(MCU to MCU):
\LP_MSPM0G3507\bsl\bsl_spi_flash_interface
Change default SPI interface from "4wire SPI-1" to "3-wire SPI-0" as below:

But the result is failed, there is no error on Host side (LED1 turns off) and Target side is able to enter BSL mode, Please help to check this issue.

Regards,

Danilo

Hi Danilo,

Would you be able to apply a scope to the lines and include your results here?

On the BSL host, did you also change from motorola 4-wire to 3-wire as well?

Best Regards,
Brian

Hi Brian,

I have tried "4-wire SPI-0" is OK to doing fw update but trere is no respose if use "3-wire SPI-0".
And the BSL host has been chane to 3-wire as well.

Thanks,
Kenny

Hi Kenny,

I'm sorry for the delayed response, solving this took longer than expected. The attached Plugin and Host projects should achieve the desired results.

Hi Kenny,

When the initial Host project was attached, I had been using different pins for SPI. This has been updated and both projects use the same SPI pins.
