Questions about Configuring the De5-Net FPGA Board

Hi,

I also meet the same problem. May I know if you have solved that?

Hi Chris,

I didn't solve this problem yet. After you downgrade the kernel, did you install it successfully?

I use the 14.04 of Ubuntu. Should I downgrade it into 12.0 of Ubuntu?

Thanks

The kernel is too new. Downgrading your kernel will solve the errors shown above.

I am not using Ubuntu for the fpga board. But you can check the kernel version to decide which version to roll back to. The kernel should include a set of macros (such as __devint).

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

Hi oni,

Thank you so much for you reply! I have followed every step and then run make_all.sh, but I got the following error messages and didn't result in the file ecliptic_drv.ko:

I hope I could get your reply and deal with this problem.

I should probably post a patch file at some point, but it is the __devinit, __devexit and other such macros that are causing issues as they are not defined in the altera lib and therefore I assume they are defined in the older kernel headers. Remove all these and try again.

Cheers

It that the same problem above?

I am looking for your reply online and hope I would deal with it.

Hi B,

I have deal with the problem successfully!!

Thank you so much for you reply and help!

Np! I think I just commented out these lines as they seemed to me to be an edge case, though this might come back to bite me later on :S

Hi B,

After everything was setting and compile the test code of OpenCl successfully, when I tried to run the file, I got the following errors:

storm@storm:~/altera/15.0/hld/board/de5net_network/tests/matrix_mult/bin$ ./matrix_mult

./matrix_mult: error while loading shared libraries: libalteracl.so: cannot open shared object file: No such file or directory

Do you know what is the problem? I have followed the manual step by step to set up.

Thank you,

Jiawen
