Did you read the hm2_spi manual page?
man hm2_spi
hm2_spi uses the unix spi driver so the path to the driver must be included in the command line that launches hm2_spi

1.
I had read the hm2_spi manual(linuxcnc.org/docs/2.7/html/man/man9/hm2_spi.9.html).
And I checked the file in the default folder ( /dev/spidev1.0 ).
I found that I don't have the file named "spidev1.0", but there are "spidev0.0", "spidev0.1", "spidev2.0", "spidev2.1".
So I tried to change the default folder. The error shows as follows
Since the error shows permission denied, I also tried to do it at root.
However, I even can't use halrun at root.
2.
Since I found this (forum.linuxcnc.org/27-driver-boards/30548-mesa-7i90-in-spi-mode ).
I also tried to install mesaflash, but it didn't work, either.
The error are as follows
Does anyone know the reason of permission denied?
Is it because of I execute these commands without linking the mesa 7i90 card ?

Not sure, on the RPI you need to specifically enable SPI access to run mesaflash
It may be that you have to change the SPI device permissions, though normally
halcmd uses root permissions to access hardware drivers (like LinuxCNC does)
How did you install LinuxCNC? You might also have these issues if you built
LinuxCNC from source but forgot to run the "sudo make setuid" step so LinuxCNC
and halcmd can launch drivers with root permissions.

I installed LinuxCNC following the guide of (linuxcnc.org/docs/devel/html/code/building-linuxcnc.html)
I had run the "sudo make setuid" when I tried to run "loadrt hm2_spi" yesterday.
The message showed when I ran the "sudo make setuid" were
And I ran "source ../scripts/rip-environment" and "halrun" after that.
Is there anything wrong?
P.S. The SPI function is enabled as the attached image "spi_enable" shown,

I tried to install LinuxCNC 2.7.14 on my Tinker Board S for few days.
The deb file I download is "LinuxCNC Uspace 2.7.14 Docs".
When I install it, terminal window showsDoes that means the installation done?
How should I run it?

@terry
That is the documents you have installed, not Linuxcnc.
You need the deb without the doc in the name.

What are the permissions of the SPI device?
( ls -l /dev/sp* )
I know mesaflash works on the Raspberry PI and it uses the SPI device
(and it needed to be enabled before it worked with mesaflash)

The permissions are as follows
It seems that the file can be read and write, but not executable.
Is it normal to a LinuxCNC system?
If it is abnormal, how can I deal with it ?

Not sure, I'll take a look at my RPI tomorrow and see what its SPI device
permissions are

I was finished install hm2_tkboard.c. And I loaded halrun with hm2_tkboard, but the error was as follows：
I also tried to use mesaflash utility by running this command:How can I flash firmware spi for mesa 7i90hd board?
