S32K344-How to configure to use the VRC_CTRL function

[Simon-Liu]

Hello:

Regarding using the VRC_CTRL function, I understand that I need to refer to section 43.7.3 (PMC Configuration Register (CONFIG)).
1.But how do I configure it when using the S32DS tool? Do I just need to check the two options in the picture below?

2.How do I verify that the configuration is correct? Is the output of VRC_CTRL 1.5V? Will this output be maintained during the function reset process? Will it not be maintained when entering Standby?

BestRegards,

Simon

Hi @Simon-Liu ,

     Thanks you for your interest in the NXP S32K3 product, I would like to provide service for you.

     Just as I email to you directly. 

      1. Hardware side, you need to change the S32K344 EVB ,J31 connect 2-3, as I know, the default is using FS26_VCORE method.

2. About the VRC_CTRL code

You can run the RTD Power_Ip_Example_S32K344, it also contains the LLD POWER module, I run it, and also call Power_Ip_Init(&Power_Ip_HwIPsConfigPB);

It works OK:

The LLD POWER configuration is also like you:

So, please try my suggest hardware method, and the project, add the code and test it again.

If you still have question about it, please kindly let me know.

if your question is solved, please help me to mark the correct answer, just to close this case.

Any new issues, welcome email directly, thanks.

Best Regards,

Kerry
