MSPM0G3518-Q1: An Inquiry Regarding Application Debugging on MSPM

Part Number: MSPM0G3518-Q1
Other Parts Discussed in Thread: SHA-256, SYSCONFIG

I have Three Questions

1- In the attached screenshot, there is an example for how to convert the plaintext password to the hashed password with sha256. when I tried to calculate the SHA-256 over the example data "0xFECAFECA78563412C3C3A5A5FFFF0000" given that the input is UTF-8 I get the example result "0x20E5F739C8D245C0E34A9C1301C12037DA29224D9B2C0738949C8ADC49AD34CA" mentioned in the document but the document did not mention that the input should be UTF-8. So I need to confirm this with you, Is it a prerequisite that the input has to be UTF-8 because it's not mentioned in the document ?.

2- for the tool Code Composer Studio, when i set the password for unlocking purpose, should it be the plain password OR the Hashed password after applying sha-256 and further steps mentioned in the document ?.

3- for Register BSLCRC, the value of data which should generate data on should be from which Start adress and what it's length ?

Hi,

There has a useful document for NONMAIN configuration, you can check the details and examples of SWD password:

MSPM0 NONMAIN FLASH Operation Guide

The NONMAIN UG describes the input as HEX string:

Always use the original 128-bit password for the unlock.

I recommend you use SysConfig to auto calculate the BSLCRC,

if you want to modify the NONMAIN and calculate the CRC, refers to the below example and gives the example to calculate CRC:

Hello Sal,

Thank you for your Support. but I am still confused about first Question and your mentioned Screenshot.

this is the steps in the Doc which I using as mentioned in the screenshot
and I means when I use the password value "0xFECAFECA78563412C3C3A5A5FFFF0000" as Hex, the output not match this one "0x20E5F739C8D245C0E34A9C1301C12037DA29224D9B2C0738949C8ADC49AD34CA"

so my question is how I should git this value ?, please give me the answer with an example with data .

thanks and best regards,

Hi,

Can you try the example and flow detailed in the document I shared:

I verify the flow and output and test it in EVM board.

I think there has some issues on the example in the document your shared. -> it looks like select UTF-8 as input enconding, but it is not the correct way.
