MSP430FR2433: Mass erase

Part Number: MSP430FR2433
Other Parts Discussed in Thread: MSP430FR5964

MSP430FR2433; question regarding the BSL supported Mass Erase Command.

Currently when a mass erase command is sent thru BSL, the information in memory B (0x1800 – 0x19FF) will be erased as well.

-          According to SLAU550R this should not happen (?) Please comment.

-          To my understanding the Erase Segment Command is not supported in the FR24xx series ?

-          I want to understand if there is a way to mass erase only the code memory (0xC400 – 0xFFFF) and leave the information block untouched?

-          Does the mass erase command work exactly the same way in the MSP430FR5964?

 

The BSL version in use: 0.8.35.B3

    Hello Kenka,
    unfortunately we have been able to confirm the observed behavior. According to our first tests on this the mass erase on both, transmission of wrong BSL pass word and the call of mass erase both erase main memory and information memory.
    We're currently investigating, if this applies also for the FR59xx devices.

    To address the specific case, the question would be, what the intention on the mass erase execution is, as unlike the MSP430 FLASH devices, the FRAM devices do not require an prior erase of the memory, as the memory can be written to without the prior erase.
    So the answer to your question, whether it is possible to erase just the code memory 0xC400-0xFFFF, this would mean just writing into this specific memory range, without an erase execution.

    Best regards
    Peter

    Hello Kenka,
    so the further evaluation on our side revealed that FR5xx and FR6xx are not affected. There the BSL mass erase behaves as in the User's Guide, means erases just the main memory.
    Please let us know, whether you need further support on this. Many thanks in advance.

    Best regards
