Questions about Configuring the De5-Net FPGA Board

I would not roll-back your kernel. That seems like too much effort ;)

There are a few changes one can make to get this to work in 14.04LTS Trusty Ubuntu. So far I've had no problems but I do need to test more.

Firstly, the aocl install command wont work. You need to go manual

navigate to altera/15.0/hld/board/terasic/de5net/linux64/driver

Modify the file aclpci_cmd.c removing any of the __ macros before the function declarations. Also comment out lines 442 to 434

if (dev->aer_firmware_first) {

return -EIO;

}

install the headers for your current kernel (apt-get install linux-kernel-headers)

change the make_all.sh file so the path points to your new kernel headers directory (something like /usr/src/linux-headers-3.16.0-50-generic)

run make_all.sh - this will result in the file aclpci_drv.ko

Copy this file to /lib/modules/3.16.0-50-generic/misc (replacing 3.16.0-50-generic with your current kernel)

Run modprobe aclpci_drv and then check dmesg for any problems.

Job done! So far this works for me in terms of checking for programs that are flashed to the memory. I need to perform more testing which I will
