MSP430F5438A-EP: Writing and Reading MSP430 Flash using MSP-FET

Part Number: MSP430F5438A-EP
Other Parts Discussed in Thread: MSPBSL, MSP-FET, MSP-FLASHER

Hi,

I have been developing a custom BSL for an MSP430 project, which used the "MSPBSL_CustomBSL430" BSL (version 1.1.0) as a starting point. The most significant change between the two BSLs is adding in a custom peripheral interface to the BSL — I am using the UART on P3.4 and P3.5 to communicate with the BSL after it's invocation.

I would now like to start thinking about how to update the MSP flash within a production process. Up until now, I have been using the MSP-FET and CCS to program and debug the custom BSL. It would be neat to be able to do the following from a command line:

1) Erase the entire MSP flash (that is, the information memory, BSL memory and main memory)

2) Program the information memory with vital product data.

3) Program the BSL flash area with my custom BSL.

4) Program the main memory flash with my own application.

Would I be able to do all of the above using the MSP-FET programming box, from the command line? If not, what would be the alternate solution to recreating the four steps above? Any pointers would be greatly appreciated.

Hi KM,

Yes, you could use the BSL scripter to perform these actions via command line.

Hi Eddie,

Thanks for your prompt response. I believe the user guide details how to update the main application flash and information flash, but it does not detail how to update the BSL flash area.

How would I go about (i) erasing the default BSL (that was programmed at factory) and (ii) program my custom BSL into BSL flash?

Ideally, I'd like to do this from the command line (so it's easily portable into a production test suite).

Best regards,

Main, information and BSL, are the same flash memory with only difference that there is lock/protection mechanism for info segment A (that is free for user on 5xx family) and BSL (where at the end is stored JTAG fuse value too). All of this flash memory can be erase/write by SBW / JATG master as MSP-FET.

For CLI check old TI open source (working on any OS) MSP-Flasher (www.ti.com/.../MSP430-FLASHER), or new (don't remember name right now) non-open source with GUI, similar to MSP-Flasher, but with GUI.

Hi Zrno,

Thanks for bringing those tools to my attention. I haven't had much luck in getting them to do what I need of them. However, for now, CCS will do the job for what I require.

Best regards,
KM
