CH382L, M.2 to PCIe adapter on SBC not recognised by Linuxcnc

Thanks for your suggestions. I'm not looking to invest in rather expensive stuff currently as I already have a working setup that is not using linuxcnc.

I may try the pin shorting method, but if driver installation is needed anyway and if I can't pass this step, pin shorting method won't be effective.

"One thing I would do is to insert a known working PCIe card of any type, LAN card might be best as Linux recogonises almost all, if this works you can rule out the first link in getting this to work."
That's right. I thought of that and will end up doing this if I will be able to install the driver first and see that it still isn't working.

If M.2 to PCIe adapter is an issue somehow, I can move to a board with PCIe slot but again, driver issue should be sorted out first.

The funny thing is the pc_parport driver & others are loading. If you look at the github page for the driver it seems only related to the serial port portion, they even admit the standard serial port driver is ok.

What do the following show ?
sudo dmesg | grep parport

sudo ls /dev/par*

sudo cat /proc/ioports | grep parport

Thanks for your suggestion tommylight. I will try this. I will keep looking into trying to make linuxcnc work from time to time but I need to get my actual works done too. I will be on this topic.

sudo dmesg | grep parport and sudo cat /proc/ioports | grep parport outputs nothing.
sudo ls /dev/par* outputs "no such file or directory"

A little more info
The kernel should load parport_serial for the following PCI ids
1C00:3250
1C00:3050
which should be the PCI ids for your card in either 2S1P or 1P mode.

Even if you can build the driver, there's another here github.com/WCHSoftGroup/ch35_38x_linux I'm doubtful if the drivers would load in your current setup. This driver seems to be able to use some of the more advanced features on the serial port side.

If you have a pc you can insert the card into you could boot linuxcnc live and see if the card is recognised.

Cant do this anymore bye all wrote:
