MSPM0G3506-Q1: The Flash configuration for MSPM0G3506-Q1

Other Parts Discussed in Thread: MSPM0G3506, SYSCONFIG

Hi,

When using MSPM0G3506 with 64K FLASH and clicking on Start Debug Session under Keil to enter the debugging page, it will not stop at the first sentence of main(), but will directly enter the HardFault_Leader.

After careful inspection, it is not a problem with the source code itself. If a few source code statements that should not be affected are deleted, it is still OK.

In the. map file of the compiled result, the value of Region $$Table $$Limit just exceeds 0x000008000. When a few lines of code are reduced and it does not exceed the limit, there is no problem. Alternatively, without reducing the code, simply changing the optimization level from - O0 to - O1 and reducing the code segment is not a problem.

But now that the FLASH space is within 0x10000, only half of it has been used and it has not exceeded the limit. Why is it like this?

Hi Zhang,

Few questions here:

1. Any compile error?

2. Do you use the Sysconfig? If yes, have you change the device to M0G3506?

3. If you use sysconifg, do you enable generate cmd file?

No complier error;

We don't use the sysconifg, this program based on the SDK from the TI website.

What's the cmd file do you use in our project? Dose it for MSPM0G3506 ?

Hi Gary,

We don't need a cmd file here, I compiled it in Keil. The engineering project is certainly MSPM0G3506, and I can compile and run it.

However, when the compiled code is slightly smaller than 32K, as long as a little bit of code is added (regardless of the code itself,

confirm that it's not a problem with the code itself), the Region $$Table $$Limit exceeds the 0x8000 address, and when downloading and debugging,

it directly enters a hardware error interrupt. By reducing a little bit of code, it can run normally.

Do you have license for the Keil? It seems if no license, it will limited to used within 32K code size.

Hi Gary,

Yes, we have the license for the Keil, pleaes help to check how to set the 64K flash that we can check our configuration, thanks.

Hi Zhang,

Please help double check if you followed the steps below to setup your software

If it still not work, could you help share me a demo code that can reproduce this issue?
