PetaLinux 2015.2 - DMA Decode Error in APF Kernel Driver for SDSoC-Generated Designs


My design has an SDSoC-generated system with automatically generated DMA blocks.

When running my test application, I see messages similar to the following:

Error : xilinx-axidma xilinx-axidma.0: Channel xilinx-axidma.0chan1 has errors 14049, cdr 380800c0 tdr 380800c0


This scenario is related to DMA decode errors where both arguments in SDSoC are using DMABUF handles.

This is resolved in the APF kernel driver and is available in the xilinx-v2015.2.02 tag in the Xilinx Linux kernel Git tree as well as in PetaLinux 2015.2.1.
