Your assumptions are correct for both the table and the block.

Hi meister,

Really cool project! I was thinking about combining FPGA support and  LinuxCNC on an  Ultra96  board (Xilinx/AMD Ultrascale device, 4x ARM64 cores and FPGA on the same chip) for years, but had no clue how the HAL messaging works. But with your UDP example as a base it was really easy! Below is a pic of the demo system, which is the Ultra96 itself, a simple self made interface board and the CNC Shield v3.0 at the top. And of course a video . :-)When I was done I saw you had added and experimental "axi" plugin and it looks like you had the same idea like me, but it did not work for me. In case you are interested, I could send my versions of the verilog and and c-code portion and maybe you could add it in a later version of your code generation magic.

oops....sorry.

That's nice mate, but my reply was to the OP.

The SmartSerial is also a latency related issue

Pinning the Ethernet IRQ to the top processor in conjunction with isolcpus=LastCPU
can also help a lot (LastCPU =3 for a 4 core processor)

This script can do this temporarily:

 

Thanks to all, I reinstalled, then installed dkms-r8168 pkg. This fixed the issue.
Now the driver is r8168 instead of r8169.
