Why does Cyclone V SoC CAN data corrupt in Linux? - Why does Cyclone V SoC CAN data corrupt in Linux? Description Due to a problem in Linux-socfpga kernels before to 4.1.33 for Cyclone® V SoC, CAN data may be currupted. This is due to a HPS L4 Slave Interface limitation, registers on CAN controller should be accessed with 32-bit width, and are incorrectly accessed as 16-bit. Resolution socfpga -4.1.33 LTSI or later have fixed in the issue.
