HVBMS s32k358 project

Hi :

Currently, I try to develop BMS system based on s32k358 platform. I already refer the "HvBms800_774_772_TPL_Bring_Up" source code to develop.

Back to original code and EVB from NXP, I use this project and run on NXP RD-K358BMU board, I found that GeneralError would return error after system run about half to one hour. The error always related to SL layer part such as "ERROR_CMU_READ_MEASUREMENTS_SME3_ERROR".

I wonder know that is there a project or bring up source code without SL part? Because I can't figure out the problem. Really need NXP's help, thanks a lot.

Thanks

BR, BillWen

Hi BillWen,

Here is the feedback from HVBMS team:

Inside the Bms SL demo part there is a counter that limits the usage to a number of calls, to protect against production usage of demo SW. This feature is inside our SW since the first release in 2021.

So this is the intended behavior of our SW to avoid this, the customer should buy the premium.

If they do not then, they will have to handle the TD extraction by their own.

Best Regards,
Robin
