User space application access to Hardware. HPS FPGA bridge

Dear all

I think I have found a begging of a workaround.

If you encounter a similar problem like me, here is the process :

- first of all enable also the standard HPS-2-FPGA bridge in your Qsys system

- follow the same instruction here https://lists.rocketboards.org/piper...st/003260.html

then it is possible to access the FPGA bridge from U-boot

I am able to run a bare metal application and access the registers.

But still not able to do a mmap in Linux userspace (of course with the administrator's rights)

Regards

Mathieu
