MSP-EXP432P4111: MSP432P4x1x

Part Number: MSP-EXP432P4111

Hi, we busy with both the EXP-MSP432P401R and EXP-MSP432P4111. We are using them using, as a start, with "oad_firmware_update_MSP_EXP401R(MSP_EXP432P4111).

We noticed that for the MSP-EXP432P401R updating the SAP works, but for the MSP-EXP432P4111 not! Using debug we see that something goes wrong with the CRC32, which is used from ROM. This could just be an indication that something else goes wrong in the first place. Comparison of the code of both projects gives no solution. So now we want to see if there are differences in the bootladers. The question is now, where can we find the source projects for the bootloader? Is it "oad_bootloader_source_MSP_EXP432P401R(4111)_nortos_ccs? For these we use the following basic settings:

- Compiler: TI v18.12.2.LTS
- SimpleLink MSP432P4 SDK: 3.20.0.06
- SimpleLink SDK BLE plugin: 3.2024

I also took some time to check whether the upload of a new version came correctly into the flash and, apparantly it does! I now think of checking the crc32 by adding a software check and see if the checksum comes out ok. Could you direct me the correct crc32 source code to implement? 

We noted several errors here, one of which:


Please advise, do we have the right source projects for the bootloader(s)?

regards,

Laurent
