mesambccc.1.adoc - wrong name of port

[zz912]

I spent almost a whole day on this.

In the documentation it says:
loadrt hm2_modbus ports="7i96s.0.pktuart.0" mbccbs="/path/to/myfile.mbccb"
and it should be:
loadrt hm2_modbus ports="hm2_7i96s.0.pktuart.0" mbccbs="/path/to/myfile.mbccb"

linuxcnc/docs/src/man/man9/hm2_modbus.9.adoc

Line 58 in e2f089d

loadrt hm2_modbus ports="7i96s.0.pktuart.0" mbccbs="/path/to/myfile.mbccb"

The problem is that I couldn't figure out from the documentation where to find the port name.

I tried:

The problem is that if the name is wrong, it doesn't write any message indicating that there is a problem with the port even with debug=5:

loadrt hm2_modbus ports="7i96s.0.pktuart.0" mbccbs="/path/to/myfile.mbccb"

That is an unfortunate typo. Needs to be fixed to state ports="hm2_7i96s.0.pktuart.0".

The problem is that I couldn't figure out from the documentation where to find the port name.

Yes, that is a bit of voodoo in the hostmot2 software. It turns out that the hostmot2 driver automatically exports the names of all hostmot2 devices when it iterates the hardware/firmware configuration of the card. So, if you have firmware that does not have pktuart support, then you never get any exported. If there are one or more pktuarts, then they will all be exported (with names ...pktuart.0, ...pktuart.1, etc).

But I see the problem, the hm2_modbus.9 manpage second paragraph under the description heading only states The Mesa FPGA board must be flashed with a PktUART capable bit-file....

I think a "how to" document should be added to go through install and config step-by-step. I never got to the point where I had the time to add it.

The problem is that if the name is wrong, it doesn't write any message indicating that there is a problem with the port even with debug=5:

Indeed, debugging is hard when nothing is mentioned. Needs to be looked into.

hm2/hm2_7i96s.0: created PktUART Interface function hm2_7i96s.0.pktuart.0.

But this was at least stated ;-)

HAL: initializing component 'hm2_modbus'

smalloc_dn: shmem available 882696
HAL: removing component 41
HAL: component 41 removed, name = 'hm2_modbus'

This is very odd. The code, after creating hal-pin 'hm2_modbus.0.last-error-code' is to get the version of the pktuart interface (which should be 2 from your listing). If that fails, then you should get an error message error: Cannot get PktUART version (error=...), but that does not happen. You should then be getting a warning: PktUART version is less than 3 (Rx=2 Tx=2). Please consider upgrading.

Nothing of the kind happens. That makes me wonder if there is a crash in the hostmot2 side while getting the pktuart version.

What version LCNC are you running?
Can you also please post/attach the mbccs (xml source)?

[zz912]

I use RIP installation. I still use newest version master branch.

Here is my whole configuration:
DedaCNC-010.zip
xml file is in modbus folder.

I have mesa 7i96s with 7i96s_pktv3.bin

[BsAtHome]

I've been rereading you output log and it certainly looks like a crash.

./DedaCNC-010.hal:10: waitpid failed /home/zdenek/linuxcnc/linuxcnc-zz912/bin/rtapi_app hm2_modbus
./DedaCNC-010.hal:10: /home/zdenek/linuxcnc/linuxcnc-zz912/bin/rtapi_app exited without becoming ready

This states that the realtime part exited. That is not supposed to happen. We need to debug this crash/exit.

Just a reminder: If you do not want to use debug, you need to set it to debug=-1 (or simply not specify it as argument) so it wont change the system setting. Setting debug=0 (zero) will suppress and disable all messages.

[zz912]

What bothers me:

I would add here:

linuxcnc/docs/src/man/man9/hm2_modbus.9.adoc

Lines 12 to 15 in e2f089d

	*ports* [default: <empty>]::
	A comma separated list of PktUART HAL names to use as Modbus hardware
	channel. Each must be matched with an MBCCB file specified in the *mbccbs*
	parameter. Example: `ports="hm2_7i96s.0.pktuart.0","hm2_5i25.0.pktuart.2"`

The correct port name is displayed in the terminal when starting LCNC while loading the hostmot2 component.
Or something like it.

hm2_modbus uses the term "port"
Mesa HostMot2 uses the term "PktUART Interface function"

hm2/hm2_7i96s.0: created PktUART Interface function hm2_7i96s.0.pktuart.0.

I think this should be unified, or added to the manual:
"port" = "PktUART Interface function"

[BsAtHome]

The term "port" is inherited from the old driver and refers to old times' serial "port", which it actually is.
See https://github.com/LinuxCNC/linuxcnc/pull/3823/changes for changes.

Could you do some printf debugging? I have a suspicion that the culprit is in getting the version because all output seems to stop there. The following diff puts some printfs in there to see what happens.

(only works on uspace and not on RTAI)

Could you send me new hm2_modbus.c ? Git is not my friend.

[BsAtHome]

Sigh! I can't upload files to github, apparently. It always says it failed.

Use this link instead: https://www.vagrearg.org/upload/hm2_modbus-20260222173700.zip

LinuxCNC terminated with an error.  You can find more information in the log:

    /home/zdenek/linuxcnc_print.txt
as well as in the output of the shell command 'dmesg' and in the terminal

[BsAtHome]

This is strange. You have a successful run and a failed one?!?

Anyway, the failed run returns with -ENODEV, which indicates that the underlying hostmot2 driver has failed to locate the hm2_7i96s.0.pktuart.0 instance, even though it said it was created. That is very strange. Either it got removed by some event or there is a race to access the information. I need to think about this.

When does it succeed and when does it fail? Random or can you force this failure in a consistent way?

On a side note, it also shows that there is a missing output flush because the error message hm2_modbus.0: error: Cannot get PktUART version (error=-19) should have printed.

[zz912]

OK test:
loadrt hm2_modbus ports="hm2_7i96s.0.pktuart.0" mbccbs="/home/zdenek/linuxcnc/configs/DedaCNC-010/modbus/h100.mbccb" debug=-1

NOK test:
loadrt hm2_modbus ports="7i96s.0.pktuart.0" mbccbs="/home/zdenek/linuxcnc/configs/DedaCNC-010/modbus/h100.mbccb" debug=-1

It is not random.

[BsAtHome]

Ah, well, that explains it... The trouble is that the error message never got printed.

I have a version here that performs a flush before quitting. Could you try again and see if that prints the error before crapping out? Thanks in advance.

Oh, and make sure you are not running with debug=0 or nothing gets printed...
