I am using a Wedge100BF-32X programmable switch and trying to setup Intel P4 studio SDE in this switch to run P4 programs. When I try to run a P4 example program tna_resubmit
with P4 studio SDE using the following command,
root@localhost:~/bf-sde-9.9.0# ./run_switchd.sh --arch tofino -p tna_resubmit
I am getting the following error:
connect failed. Error: Connection refused
The full output from the command is here.
Environment:
P4 studio SDE version: 9.9.0
uname -r: 4.14.151-OpenNetworkLinux
cat /etc/onl/platform: x86-64-accton-wedge100bf-32x-r0
ls /dev/bf0: /dev/bf0
lsmod:
Module Size Used by
bf_kdrv 24576 0
pmbus 16384 0
pmbus_core 28672 1 pmbus
x86_pkg_temp_thermal 16384 0
gpio_ich 16384 0
optoe 20480 0
A user on Github suggested reloading kernel driver and checking if /dev/bf0
exists. I did them both, but the issue remains. Any help would be appreciated.

Hi,
This seems to be Tofino issue but not FPGA issue, do you mind to look for the correct place to raise the question?
You may take a look into https://community.intel.com/
Thanks,
Best regards,
Kenny Tan
