No such device /dev/switchtec0 after installing switchtec.ko

[zhileiz]

Hi, I'm new to using switchtec and would appreciate any help to get started.

I'm using MICROSEMI PM14100 board on a Dell Precision Tower 5810.

I'm running ubuntu 18.04.5 LTS desktop.
uname -r output:

5.4.0-74-generic

I cloned this repo and checked out branch backport_5.3_to_5.4 and ran:

make
sudo make install

make install gives following output:

make -C /lib/modules/5.4.0-74-generic/build M=$PWD modules_install
make[1]: Entering directory '/usr/src/linux-headers-5.4.0-74-generic'

Warning: modules_install: missing 'System.map' file. Skipping depmod.
make[1]: Leaving directory '/usr/src/linux-headers-5.4.0-74-generic'

Then I did:

sudo modprobe switchtec
sudo modprobe ntb_hw_switchtec

Now if I do lsmod | grep switchtec, I get:

ntb_hw_switchtec       28672  0
ntb                    20480  1 ntb_hw_switchtec
switchtec              36864  1 ntb_hw_switchtec

However, when I run switchtec-user command switchtec list it returns:

free(): invalid pointer
Aborted (core dumped)

and python ./scripts/test.py also throws:

FileNotFoundError: No such file or directory: '/dev/switchtec0'

and there is no switchtec* device in ll /dev output.

Any suggestions? Thank you.
Also if anyone could point me to an official manuel/specification of the board, that would be helpful too.

Likely culprit is the switch isn't configured to have the management endpoint. Seems it's disabled in default configurations.

You'll probably need to contact Microchip support for help configuring the device and to get access to the documentation.
