7i80 and uart test was created by sneci
Hi,
I'm testing the uart component with a 7i80hd card. The setup runs without errors. An error message comes after the halcmd: start:
It seems to work with hm2_pci, but hm2_eth runs here in error.
(forum.linuxcnc.org/27-driver-boards/3711...o-linuxcnc2-8#141396)
Note: Check out Andy's change in mesa_uart.comp.
Some info:
system: Linux pcb 4.9.0-8-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.144-3.1 (2019-02-19) x86_64 GNU/Linux
firmware: hd_25_svstua4_12_4d.bit (forum.linuxcnc.org/27-driver-boards/3749...ile-with-uart#146551)
hal script:
I tried under linuxcnc-dev and from github with 2.9pre installation. The error is the same.
What do you suggest?
Thanks, sneci

I suspect the best solution would be to use the Packet UART instead

thanks, I'll see what it is 
I know the name, but I haven't worked on it yet.

I need some help.
I made a pin configuration with pktuart content. Editing and syntax checking is handy with Xilinx 13.4 WebPack. The code is fine, but I can't make a bit file. This project comes from mesanet.com 7i80.zip.
The bit file is created using the github hostmot2-firmware package. Downloading the generated bit file to the card comes with the same error as in the forum.linuxcnc.org/27-driver-boards/3749...25-bitfile-with-uart topic:
The problem comes from the environment. The PIN file received from Peter has been processed incorrectly here.
My question is: Can Xilix WebPack generate a bit file itself?
If not, how do I generate a bit file?
Thanks,
sneci

Yes all my bitfiles are generated with the free Webpack
Are you sure you created a PktUART config?
The error suggests you have a standard UART config
(and the standard UART needs a Top level source file tweak = instance stride1
must be set to 16 rather than 64) The PktUART needs no tweak

The convincing check was that I also made a bit file with your SVSTUA .. configuration. That also brought the error. It looks like the github is not compatible with mesanet packages.
Please take a look at the attached PKTUA pin configuration, I hope I didn't make a mistake.

Thats UART config (not PktUART) as I mentioned, you need to change the instance stride1
or you will get an error with UART configs (and UART config will have issues with Ethernet)

You're right, stride 1 is correct.
But unfortunately there were new problems.The pktuart.c component does not see the functions of hostmot2.c.
Unfortunately, I have to stop the much promising trial here. I am now solving this communication in user space. No more time now.
Thanks for the help

I dont think you are supposed to load the pktuart module (its part of hostmot2)
(I just tested with the mesa_pkt_gyro component and it loads properly)
Untill Hal adds a array or string type, dealing with UARTs will be awkward

That's really good news. I treated it as a normal hal component. I'll check it out tomorrow ...
