MSP430FW423: MSP430FW423 binary running on MSP430FW429

Guillaume Henri

Part Number: MSP430FW423
Other Parts Discussed in Thread: MSP430FW429

Hi MSP champs,

It sounds like that MSP430FW429 is similar to MSP430FW423 (peripheral addressing, pinout, ...) except that the RAM and Flash are bigger on the FW429

Do you confirm that a MSP430FW423 binary (compiled for FW423) can run as is on MSP430FW429 without any recompilation ? (ie no difference on Flash/RAM lower memory mapping or some specific memory flash registers value differences for instance)

Thank you!

Best regards,

Guillaume

Hi Guillaume,

I'm not seeing any other differences from the data sheets. As long as the binary doesn't check the information structure somewhere, I would expect the binary to work.

Hello Leo,

Thanks for your answer!

When you mention "information structure", do you refer to "256-byte Flash Information Memory" located at 1000h address?

As I understand on the different registers of such information memory, there is no difference on these registers depending on FW4x part number. So even if the binary chech this information memory, there should be no issue. Am I right?

Thank you!

BR,

Guillaume

Hi Guillaume,

Agreed. If the information is the same between these two parts in this section, there shouldn't be a compatibility issue between them.
