Hi,nxp team:

I'm having trouble reading the timestamp on pfe2, it always reading zero.

I'm use bsp35,pfe driver version is 1.2.0,FW VERSION is 1.5.0.

I checked the documentation<< LNX PFE Driver User Manual>>, p2.6  IEEE1588 Support.Make sure my code is configured according to the documentation.but I can't get the ts time from pfe2.

root@s32g399ardb3:~# devmem2 0x46000b08
/dev/mem opened.
Memory mapped at address 0x7fb7097000.
Read at address 0x46000B08 (0x7fb7097b08): 0x00000000

Hi,

We understand that the address you are reading is related to pfe0, but you are using pfe2. This might be why you are not seeing the information under the related registers.

Still, could be that we are misunderstanding your request. If so, we apologize.

Please, let us know.
