SmartSerial broken - Githubissues

I've pointed this out in the Machinekit Group but figured I'd post here as a reminder. The Mesa SmartSerial function appears to be broken in this project. I'm unable to test other projects so I'm not sure how far up the ladder it goes.

Tests were done with GPIO1 pins 00+01, as SS rx and tx, using a couple of different RS422 circuits trying to communicate with a Mesa 8i20. I was not able to get this to work. I reached out to PCW on the LinuxCNC forum and basically came to the conclusion that since the SmartSerial version printed on Machinekit startup shows as "version 0" it is broken at the firmware level. Machinekit does not print to the terminal the same way LinuxCNC does but the instantiation of HM2 modules will sometimes dump to a logfile in /var/logs/linuxcnc.log as seen below.

Sorry that this was/is not more clearly globally stated, however: The DExx ..._Cramps projects are minimalistic as only the hm2 cores in current configs are included, so SSerial and @blazini36 'c config added here: https://github.com/the-snowwhite/mksocfpga/tree/sserial-work

@cdsteinkuehler @blazini36 I modified the Title

There is definately something (not) going on. I noticed that the tx pin was floating (also in the ..._DB 25 7i77_7i77_7i77_7i77 bitfile) All the SSerial pins actually show up and act/behave as ordinary GPIO pins. here a copy of the commands I used and also the linuxcnc debug output:

No SSerial pins

BTW found this explanation of the sserial_port_0=00xx parameter, this seems to be for 2 SSerial cores in config ? https://forum.linuxcnc.org/32-documents/26138-hostmot2-sserial-port-n-xxxxxxxx

It's just a typical usage, setting a SS core to mode 0 that does not exist should not cause an issue, it's a carryover from MESA boards that use the first channel for onboard I/O and include an expansion port. If "sserial_port_0=0xxx" made a difference I'd be shocked.

I'm still wrapping my brain around your findings trying to compare it to a typical LinuxCNC setup since I don't have much MK experience otherwise.

Carryover from The MK GG..........

I'm not sure if this helps you but SS pins always look like normal I/O if they don't detect a remote on the channel after coming up. Since I have it out I connected the 8i20 to my project machine's 7i96 that I don't typically use SS with. This is LinuxCNC 2.8pre1

No 8i20 connected, note IO pins 30 and 31:

OK SSerial.c states that pind don't get created if nothing is probed and that the Tx pins are only momentairly enabled for initial probing so I did a new set of scope probing and got some results:..

It's definately a message but I'm not sure if it's the right message or the right timing, I was getting something similar when I checked before you made changes to the firmware source. According to Peter Wallace, you should see a 0xDF and the timing is 2.5mbaud.

According to the manual for your scope, assuming this is the one, it can do serial decoding. If you can set it up to decode rs232 @ 2.5mbaud you might see something.

Page 3 of the manual https://www.picotech.com/download/datasheets/MM043_PicoScope_Serial_Decoding_Data_Sheet.pdf

SSerial-Serial_Decoding:

SSerial-Serial_Decoded

Well I do see DF as first byte ... ?

i use this exact hal command sequence:

halrun
loadrt trivkins
loadrt tp
loadrt motmod servo_period_nsec=1000000 num_joints=3 num_aio=51 num_dio=21 tp=tp kins=trivkins
loadrt hostmot2 debug_idrom=1 debug_modules=1
newinst hm2_soc_ol hm2-socfpga0 already_programmed=1 -- config="num_stepgens=3  sserial_port_0=00xx" debug=1

I'd say that transmission looks good, doubt it's a coincidence. I'm still not getting any where, trying to figure out if a simple rs232 shot to the 8i20 from the Nano will work to eliminate any hardware problems.

I have been looking at the source files machinekit-hal/src/hal/drivers/mesa-hostmot2/sserial.c and sserial.h there is only 1 update (to sserial.c) in machinekit(-hal) since 2015 as to the ones in the lcnc repository which have noticable differences.(especially compairing the 2 hm2_sserial_parse_md function's )

Due to a lack of confimation of a working Mksocfpga SSerial setup...: If it were me I would test out Machinekit'fying a copy of the sserial.c and sserial.h files from linuxcnc repo, (rtapi_u32 -> u32 )and see if that does the trick.

If you fix and compile them, I'll try em out!

Also, if it's the case that it's broken in MK in the hm2_driver MK is using, it would probably be best as an issue moved to the MK-HAL repo right? At least for someone maintaining that branch to look into.

Honestly, MK's major hardware use is a BBB or an obscure arm SBC, I doubt anyone has really used Mesa SS with machinekit since it's inceptionor shortly after, the common hardware and the daughtercards people attach to them don't really facilitate SS. mksocfpga is probably the most serious use case for SS with Charles's DB25 adapers or whatever else might pop up for an socfpga board.

OK give me some time

mk-hal deb for test with sserial parse only mod. Here: https://groups.google.com/forum/#!topic/machinekit/eVhvTnuhblE%5B126-150%5D

Due to the number of changes I choose to creative a conservative change only modding the: hm2_sserial_parse_md() function, this is what does the intial probing and pin setting.. The file you should use I think is: machinekit-hal-rt-preempt_0.2.1566764039.gitf3af8e09e-1~stretch_armhf.deb

I added the other one just in case...

You say there's still work to be done on the driver right?

BTW sudo dpkg -i machinekit-hal-rt-preempt_0.2.1566764039.gitf3af8e09e-1~stretch_armhf.deb ?

Ups I forgot to refresh and overlooked your former message

You say there's still work to be done on the driver right?

I have no idea.... Test if the rest of it works as supposed to, execpt from what seemed like an obvious flaw in the parse function (that hunch turned out right as you report).

(unless your: quick mod to your prototype board was the only fix needed....)

.I dont have the Machinekit knowledge to be able to see in the source code if the other lcnc mods are mk compatible therefore I left them out.

Can I pursuade you to purge the machinekit-hal package and re-install the one from the repo, just to be double sure of the need of the software mod ?

It did get a bit confusing since I was changing things around quite a bit trying to get it working until the quartus firmware issues were resolved. I very well could have screwed up my hardware in the meantime.

You'll have to tell me if I removed and re-installed everything satisfactory: Ran: $ sudo apt purge machinekit-hal-rt-preempt Which removed machinekit-cnc as well, but not any config files. Then: sudo apt-install machinekit-hal-rt-preempt and sudo apt-install machinekit-cnc-rt-preempt

Without re-installing the MK-hal deb you sent I still have discovery of the 8i20. It's easy for me to image the SD card so If you want me to remove anything else to be sure let me know.

Actually I will say that there are probably still some issues but I'm not sure at which end they lie. The 8i20 flashes the status LED, then goes into fault. I assumed this was because of the fact that I don't have any HV motor power hooked up to it. I can verify that My LinuxCNC machine gets a steady heartbeat flash on the status light with nothing hooked up to it other than the serial cable. Log shows the following error:

This message will not be repeated, but the hm2_5i25.0.sserial.0.fault-count pin will indicate if this is happening frequently.

Hard to say when the hardware can obviously manage the handshake and discovering pins/parameters. I don't believe individual boards are identified in hm2, that's all done through discovery right?

Your removal and re-install commands look okay.

It did get a bit confusing since I was changing things around quite a bit trying to get it working until the quartus firmware issues were resolved. I very well could have screwed up my hardware in the meantime.

Yeah most probably what happened and what is now giving the "DoIt not cleared from previous servo thread", error.... Perhaps you should clear your SSerial interface experience logs and work back towards your original HW design from when the SSerial hdl core was missing and start over...

I didn't make any software changes other than installing the deb you packed up. The hardware as is connects to a LinuxCNC install without issue. the "DoIt not cleared from previous servo thread" is where we're at as far as MK goes.

OK I'll try building a full Mk modded sserial.c/h and see where that goes...

OK Lcnc SSerial Mk modded (without rtapi_stdint.h): posted in the GGroup

I did kind of have the thought that maybe SS did did discovery at a lower baud rate and then switched to the 2.5mbaud. Kind of thinking that maybe on the hardware side there were signal issues at higher speeds.

PCW confirmed that SS runs at 2.5mbaud the whole time from discovery to actual operation , but that’s all he really said. So I have to think that if my board can handle discovery which is 2 way communication @ 2.5mbaud, then there’s no real reason it should have comm errors afterwards.

I wish I knew more about it but for now I’d have to assume the hardware is good and your new firmware is good.

Let me know when you get around to testing the lcnc ssreial SW mod... and how it fares :-)
