Install driver petalinux - not seen both interfaces

[mihai5]

Hi,

    I installed also petalinux 2015.4 (beside 2017.2) in the scope of solveing my problem, but without success. I want to integrate a kernel driver into petalinux rootfs to comunicate with an PL block which has 2 interfaces (lite interface and full interface - both memory mapped). When i created the module into petalinux, i let the code as it was generated..just i overwrote the ".compatible" section with the comptabile section from pl.dtsi(in my case <xlnx,accHW-1.0>)

   At insmod it doesn't output both conversions (phisical to virtual adresses). It shows just the conversion for the lite interface (0x43c0 0000 to 0xe09a 0000).

root@Avnet-Digilent-ZedBoard-2015_4:/lib/modules/4.0.0-xilinx/extra# insmod driv

What i have to change in driver code to see both conversions ? Or where can i see them ?

Hi @mihai5,

I do not have much experience with embedded linux. I have reached out to my co-workers to see if they have some input for you.

cheers,
