LP-MSPM0G3507: MCAN cannot switch to NORMAL mode after SW-INITIALIZATION MODE

Part Number: LP-MSPM0G3507
Other Parts Discussed in Thread: SYSCONFIG, CCSTUDIO

Tool/software:

This is a random issue (about 10% of the time) in "ti_msp_dl_config.c" file.

In CCS studio I found that in the code: -

DL_MCAN_setOpMode(CANFD0, DL_MCAN_OPERATION_MODE_NORMAL);

while (DL_MCAN_OPERATION_MODE_NORMAL != DL_MCAN_getOpMode(CANFD0));

after the MCAN is initialized the execution is stuck in the above mentioned while loop, as mentioned above this is random and many times the software works fine and I am able to Tx and Rx CAN messages.

Please help in identifying the possible causes for this kind of issue?

Hi Ankit,
I recommend downloading the latest version of the SDK, SYSCONFIG, and CCS. Let me know if that fixes it.

I'm having the same issue as OP, and I'm using the latest versions; my current environment is:

CCS Theia 1.5.1

MSPM0 SDK: 2.3.0.7

SysConfig: 1.22.0

Hi Rob,
I recommend to update your CCS Theia to the most recent CCS (20.0.1.) This is the latest CCS Theia release. If the issue remains, I'll check this issue out and make a ticket about it.

Hi Rob,

CCS Theia is a name that TI discontinued after releasing the latest CCS. You can download the current CCS from the CCS Product Page using Theia IDE.

Thanks Diego.

I updated to CCStudio 20.0.1.4 but the issue with MCAN SysConfig persists.

Thanks,

Rob

Hi Rob,
The team is still working on this bug. Most likely it will be fixed in the next release of our SDK.

I found that the clock tree generates different code (unstable) from SYSCTL in sysconfig. Uncheck the "use clock tree" option in sysconfig.

I appreciate the advice Ankit. Unfortunately, I don't have "Use Clock Tree" selected, so it appears I may have another cause.

Glad to hear your issue was resolved!
