UNIFLASH: MSP432

Part Number: UNIFLASH
Other Parts Discussed in Thread: TMS320F28076, , MSP432E401Y

Hi,

I'm using Uniflash CLI to flash two daisy chained CPU's: a TMS320F28076  and a MSP432E401Y.

I'm using XDS100v2 USB Debug Probe.

Flashing works fine on both CPU's, but I can't configure the option "FlashEraseSelection" on MSP432E401Y.

I need to use this option because a bootloader and an application need to be flashed on MSP432E401Y, so the application flashing must not erase the bootloader.

When I set the "FlashEraseSelection" to "Erase and download necessary segments only",  dslite.bat file generates this error:

"Failed: Unknown Property: FlashEraseSelection".

I've tried to use the "-l" option, specifying the generated configuration file and also the -s option, setting the specific "FlashEraseSelection" property, but both these methods generate the aforementioned error message.

The configuration file generated by uniflash contains the following string:

{"Texas Instruments XDS100v2 USB Debug Probe/CORTEX_M4_0":{"FlashEraseSelection":"Erase and download necessary segments only"}}

As mentioned above, if I don't set this option flashing on MSP432 works fine, but, as default behavior, the flash is erased  each time before flashing, so the application flashing erases the bootloader.

Is there a way to make dslite.bat flash the needed sectors only?

Thanks,

Luca

    Hi Luca,

    What is the command being entered via CLI? Are you passing in the ufsettings file directly to dslite?

    Thanks

    Hi Ki,

    I'm using the dslite.bat file and relevant ufsettings file, both automatically generated by Uniflash. I've configured Uniflash to work with a MSP432 only configuration, in order to see the settings of the MSP432 on Uniflash menu "Settings and Utilities".

    If I load on uniflash my custom configuration, with TMS320F28076 and MSP432, I cannot see the MSP432 settings, I see only te MSP320F28076 settings.

    Anyway I've tried to use the dslite file autogenerated in this case (named dslite-C28xx_CPU1.bat), with option --core to specify the MSP432, passing the MSP432 ufsettings, but I always get the same result: "Failed: Unknown Property: FlashEraseSelection".

    As mentioned, I've also try to set the FlashEraseSelection property with option "-s", but the same issue occurs.

    Thanks,

    Luca

    How are you using the -s option? It should look like:

    -s "FlashEraseSelection"="Erase and download necessary segments only"

    Thanks Ki,

    It works now.

    I was making mistakes in the syntax.

    Glad to hear it is working for you. Thanks for the update.

    I also filed a bug for the issue with the ufsettings file. That should of worked also. Tracking ID for the bug is: UNIFLASH-1282

    Thanks
