I guess I just meant that that using halcompile outside of the norrnal LinuxCNC source tree for hm2 drivers seem odd


I agree, It might be worth trying an in-tree build, but it really did look to have gone smoothly, and it appeared to execute too.

There are no hw_intf.conf in the boot folder of my tinker.
I think it might because of that the OS I use is armbian.
So I checked the hardware function again.


And just for refrence. The result of readhmid are as follows

Are you sure that the board is in SPI2 and not SPI0?

Possibly SPI and SPIDEV are mutually exclusive?

Yes, the 7i90hd card is connect to the spi2 pin of the tinker.( pin19=TX, pin21=RX, pin 23=CLK, pin24=csN0 )



However, I cannot tell if the hm2_tkboard use spi0 or spi2 from the source code.
I connect to spi2 because the author of the driver and the youtube video tell me it use spi2.

I also tried to do the spi communication when the spi2 is turned off and when spi2dev is turned off.(test1 & test2)

test1: spi2 : off spi2dev: on;

test2: spi2 : on spi2dev: off;


Both of the test shows cannot find device.

HI I have been working on a similar project one of my post's links to a lot of information. I also have files from people somewhere who have gotten the tinkerboard working well with mesa controlelrs. The issue is you need to have a HAL driver for the GPIO. OR you can use an ethernet MESA card. but anything running via the gpio I believe needs a hal driver for lcnc. There is a guy who has been promising to produce a GPIO direct control to treat the GPIO I/O pins them selfs like a parallel port. But he has not produced any files yet that I know of. When ever/if he does I'll post them on my armbian post which I linked in an other post on/in this topic/forum. If your interested in any of the files I have on hand. I'd have to dig them out.

Sounds like the hm2_tkboard not include the GPIO driver of the Tinker board. So if I got the GPIO dirver I have to load it before I load the hm2_tkboard.

unless I'm mistaken I have a copy of the hm2_tkboard files. that are from the person who posted the lcnc using a tinkerboard. BUT.. THAT IS BASED on the mesa controller

I have tried to get printer port address form the terminal.
Here is what I got
root@LinuxCNC-terry:/home/atech# cat /proc/ioports | grep parport
  0378-037a : parport0

So I tried the readhmid command. The result are as follows
atech@LinuxCNC-terry:~$ sudo mesaflash --device 7i90 --epp --addr 0x0378 --readhmid
[sudo] password for atech: 
failed to clear EPP Timeout!

failed to clear EPP Timeout!
EPP timeout on data cycle of read(addr=0x0100, size=4)
failed to clear EPP Timeout!
No 7I90 board found

Is there anything wrong? Can anyone help me?

Yes, it have been solved.

I checked following items
1. turn the function of the parallel port to EPP 1.9
( in my PC, the function was blocked by default. It needs to change the bios version.)
2. make sure the wire is good and carefully connected.

good luck
