i.MX6 Dual lite SDK PCIe test data abort occured while accessing mapped memory

Bharath_R — Thu, 20 Oct 2022 11:16:32 GMT

Hello,

We are able to establish PCIe link setup and get Device and vendor ID.

As per RC test file, after mapping memory, while reading memory, we are getting data abort mode.

Attached snapshot below fyr.

As per the snap, we are able to read and write 1st memory base (0x1010000), but access to 2nd memory base (0x1020000) gives data abort..

shall we know why this occurred and how to use those memory to transfer data...

Thanks and Regards,

Bharath R

Hi @Bharath_R

I hope you are doing well.

In attached snapshot fault status is 0x8, that means execution format error. Can you please double check the command which was used for PCIE read data?

Thanks & Regards
