MSpBoot for MSP430F6736

Other Parts Discussed in Thread: MSP430F6736

Hello,

We are working on project where we required OTA feature to update app.We are using MSP430F6736 MCU.

We are writing download binary to EEPROM over SPI and Boot loader will read that binary and update app.

Below are quarries from our side:

1) Which boot loader is more preferable BSL or MSPBoot?

2) How can we port suggested boot loader to MSP430F6736?

Thanks and Regards,

Prashant

  • Hello Prashantsinh,

    I would definitely go with the BSL here for your project. MSPBOOT was originally created for devices that do not have an easily changeable BSL and applications that needed a different programming method outside the provided BSL.  The MSP430F6736 device has a Flash based BSL and BSL locking mechanism, so it is easy to change and customize for your specific application's needs. Please see the following BSL Application notes that describe the BSL in full and how to customize it. Also, within the Custom BSL application note, there is a link to BSL examples including different Peripheral Interfaces (PIs) that can be used. It does not seem that SPI was included in the example PIs, but all the information is available in the documents to allow you to create your own custom PI for interfacing with the BSL.
