FEC data corruption?

[woutervh]

I'm trying to do a long-term network test on 2 platforms.

One is based on imx6q, the other on imx6ul.

imx6q is using linux-fslc, imx6ul is using linux-imx

For that, I enabled the busybox inetd service with the echo protocol enabled. I'm flooding the device with echo requests of 12kiB (0x3000B)

Most of the time that goes well, but at certain points, the data returned by the platform is corrupted. After some research, it looks like the data returned is copied from memory address 0 in stead of the correct data. Any idea what can cause this?

I attach a screenshot of wireshark showing this behaviour

Hi Wouter,

There are some ENET Erratas in i.MX6Q. But it is necessary to understand how are you doing your tests to be sure that this is the case.

I have it on both imx6q as imx6dl

The test is just continously sending echo-packages (echo-protocol) to udp port 7
