qspi running pfe_master project

youke — Mon, 29 Sep 2025 09:21:13 GMT

Hi，NXP

I'm testing the S32G with rdb2 hardware, I haven't found a M core pfe master program that I can run on qspi, I just want the M core to be able to send out udp data via pfe just fine, is there a routine for that?

BR.

Hello, @youke

Thanks for your post.

Since UDP is based on IP protocol, for sending UDP packet via PFE from M core's perspective, you need to combine the PFE driver and IP stack together(for example, LWIP), I suggest referencing the demo that mentioned from example_application directory of the PFE MCAL for details.

Hi,chenyin

I have tested this routine, I now want to simply run through the ping test, I tested the cmm debugging and it works, but I can't get it to start after I flushed it to QSPI, do you have a pfe master routine available for qspi?

Hello, @youke

Thanks for your feedback

You mean that the PFE master with LWIP project works fine from your side via debugger, but failed for QSPI boot when flashed to the QSPI?

May I know which CMM file you used to test the elf file? and share the steps for generating blob image from raw binary.

Hi，chenyin

I tested debugging with PFE-DRV_S32G_M7_MCAL_1.3.0\example_application\run_main_RDB2.cmm and it works correctly;
Test qspi startup by adding the blob file as follows:

Thanks, @youke

Would you mind sharing the map file with me to have a check?

Hello, @youke

Thanks for your reply.

Would you mind changing the RAM start pointer to also 0x34390000 and have another trial?

Hi, chenyin

I followed your test modification and it didn't boot successfully (the code turned on uart1 to output the log, no associated log prints after power up)

Hello, @youke

Thanks for your reply.

May I know if it is possible to share the elf/raw binary/linker file used? I would help to check it.

If it is not convenient to share it in this public community, please tell me and I could help to create private sessions.

Hello, @youke

Thanks for your reply.

I have checked the image you shared, seems there is something wrong in clock init during QSPI boot, not sure what you may had modified upon the default settings?

Hi, chenyin

I haven't made any corresponding modifications to the initialization code; I only commented out some unused functions in the main function.
These are the QSPI-related parameters in IVT. Could they have an impact?
What other modifications do I need to make?

Hello, @youke

Thanks for your reply.

I have investigated the issue you met with the images shared, from my debugging, it is related with clock issue, some of the clocks are not enable correctly, since default settings are done for debugger purpose..

I suggest enabling corresponding clocks needed from mcu module, then rebuild the image, it should boot the board and send the frames correctly.

Hi,chenyin

Thank you for your response. I will continue troubleshooting the clock section.

Hi, chenyin

Mpu_Configuration Does this function affect the use of the PFE master? Can I skip executing it?

Hi, chenyin

Which part of the clocks does “some of the clocks” refer to?

Hello, @youke

The support case you requested is created, you may find the mail that sent for you with the detailed information, and share your private configuration/codes there conveniently.

I will continue supporting your PFE issues there.
