Due to a compatibility problem between uboot-socfpga v2022.01 and the Intel Stratix 10 SoC Design Example for 10Gbe, the Low Latency Ethernet 10G MAC Intel® Stratix® 10 FPGA IP might fail to receive Ethernet packets when using the linux-socfpga 5.15.x kernels.
The error is observed looking at the Rx errors counter when calling the ifconfig command from Linux shell. This problem also might affect designs targeting Intel® Agilex™ devices, for accesss from the FPGA via the FPGA-to-HPS bridge.
This problem has been resolved for the u-boot-socfpga 2022.01 and 2022.04 branches
- Ensure that you have the latest patches from u-boot-socfpga 2022.01 / 2022.04 branches
- Relevant commits
- 2022.01 -
- 2022.04 -
For latest hardware or software version compatibility information, refer to the User Manual for Intel Stratix 10 SoC Design Example on Rocketboards.org.
Note: The following issue might occur with the current resolution in place: How to configure FPGA-to-SDRAM interface when ECC is turned on in Intel® Stratix® 10 SX devices?
