MSP430FR2353: The sample code for firmware update

Hi Kuerbis,

I think you are looking for our BSL documentation:

http://www.ti.com/tool/MSPBSL

Specifically, you will probably be interested in the FRBOOT document that explains how to create custom BSLs for FRAM devices:

Please take a look at these resources and let me know if you have any other questions.

Thanks,

Mitch

Hi Kuerbis,

Yes, you can implement I2C for the custom bootloader. The example code will need to be changed so that it support I2C communication (like you mention above), but yes, this can be implemented There shouldn't be any limitations for implementing I2C.

I should also point out that the FR2353's standard BSL supports a hardware I2C BSL:

This BSL is hardcoded in ROM and cannot be altered, so if customization for the BSL is needed, creating a custom FRBOOT I2C implementation is what I suggest.

Thanks,

Mitch
