Reading internal RAM

[Kieutrang]

we're using the PCAN-miniPCIe Card to connect a Tegra K1(running Linux 4 Tegra) to the CAN Bus. Sending and Recieving CAN Frames works just fine. But we're looking for a way to monitor the CAN Frames before they are processed by Linux. The idea is to read the Recieve FIFO and TX Buffer directly out of the internal RAM of the CAN Controller. According to the Data Sheet of the SJA1000 this should be possible. But reading out the internal RAM does not seem to working. I just get the registers repeated all over again. Am I missing something or am I doing it wrong?

Hi,

you have to develop an own driver to realize such a feature. Please have a look on our peak-linux-driver-8.x, which is available as source.
