Configuration via Protocol (CvP) fail after loading the periphery image

Hi @JohnT_Intel ,

apd@apd-pc1:~$ uname -mrs
Linux 6.6.37+ x86_64

Steps that I took to update the kernel (following the guide that you mentioned above):

git clone https://github.com/altera-opensource/linux-socfpga

cd linux-socfpga

git checkout socfpga-6.6.37-lts

cd /usr/src/linux-socfpga

cp -v /boot/config-$(uname -r) .config

make menuconfig

- Set Altera CvP FPGA Manager and FPGA Manager DebugFS to *

Make -j 12

export INSTALL_MOD_PATH=/usr/src/linux-socfpga

MODPATH="INSTALL_MOD_PATH=/usr/src/linux-socfpga"

ARGS="$MODPATH"

make $ARGS modules

sudo make modules_install

sudo make install

grub-mkconfig

cat /boot/grub/grub.cfg

sudo cp /etc/default/grub /etc/default/grub.bak

cat /etc/default/grub

gedit/etc/default/grub

sudo update-grub

Hope this gives more insight to the problem.

Thanks,

Jon

Hi @JohnT_Intel ,

How do I generate the log file? Or where can I locate the log file?

Thanks,

Jon

Hi @JohnT_Intel ,

Yes I have done git checkout 6.6.37-lts, built the kernel and verified that it is "Linux 6.6.37+ x86_64". I have also ensured that these are selected:

• CONFIG_FPGA=y
• CONFIG_FPGA_MGR_DEBUG_FS=y
• CONFIG_FPGA_MGR_ALTERA_CVP=y

I also noticed that fpga_manager directory does not exist at "/sys/kernel/debug". Do you have any idea what could be the problem?

Thanks,

Jon

Hi @JohnT_Intel ,

I have changed to 6.6.37-lts version. However, it seems like the driver is not loaded properly. After entering lspci -vvv -d1172:, I do not see the output "Kernel driver in use: altera-cvp", and I can't upload my core image either. Is there a difference in the procedure for version 6.6.37-lts? And where else can I look to troubleshoot this issue?

Thanks,

Jon
