How can I trigger an FCCU misc IRQ in Linux?

[Jeff-CF-Huang]

Hi Sir,

We want to trigger FCCU misc IRQ to show "interrupt handler: misc. No action performed".

The detailed code can be found at the link below.
https://github.com/nxp-auto-linux/linux/blob/be2b4ba5591b690e6036c1585a960295d1972bf0/drivers/misc/f...

We have just enabled the FCCU driver. Is there a straightforward way to test it using s32cc_regacces or T32?

Best regards,
Jeff Huang

Hello @Jeff-CF-Huang,

Thanks for contacting NXP support and sorry for the late reply. I tried analyzing the code ant matching it with the information in the reference manual and BSP user manual. However I was not able to find the required process to trigger the misc IRQ. 

I raised this topic with the internal team for better support, I will come back with their feedback.

Thanks for understanding
