Duet 3 and jetson Nano?
-
@jpomo10 are you using the original 26pin to 40pin cable provided with the Duet3 or did you make one of your own?
-
Thank you for testing my config.g on your set-up.
For what it's worth, I've now tried this with a Rasp Pi running DuetPi & a Rasp Pi running Rasbian.
In both cases, I can connect to the Duet3 but cannot send gcode through DWC. That's more than I can say for the Jetson Nano, since it will not connect to the Duet at all, so I'll adjust the SPI frequency some more, as you suggested.
I also reflashed with the latest stable release of RRF 3.0. I used the binary file called "Duet3Firmware_MB6HC.bin". Communication with the board through YAT seems fine.
I'm using the original (26 to 40pin). Just to make sure I didn't somehow damage it at some point, I'll make a replacement.
UPDATE: Swapping the cable didn't make a difference
-
I'm beginning to think bad cable or bad Duet3.
-
@hanshogeland and I were just chatting about upgrading a Nano so...
Here's the latest device tree overlay file for the "b00" version of the Nano.
- Download the file to "/boot" removing the ".stl" extension.
- Run
/opt/nvidia/jetson-io/jetson-io.pyfrom a command prompt - Select "Configure Jetson for compatible hardware"
- Select "Dual SPIDEV"
- Select "Save and exit without rebooting"
- Double check that a new "Dual SPIDEV" entry was placed in /boot/extlinux/extlinux.conf
- Edit or move the entry as needed.
- Reboot
-
Thank you verry much!
*Updated this post, since I hade the wrong config for the ready pin so Iǘe changed to pin 13 as it should be.
I have ran the .py and verified the .conf however I get an error starting the DCS stating:

-
@hanshogeland I'm investigating.
-
@gtj0 This is really odd. I'm getting the same error now. Should have it fixed shortly.
-
I think this'll fix it. ..
tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtbo.stl
tegra210-p3448-0000-p3449-0000-a02-single-spidev.dtbo.stlUse the appropriate one for your board and double check extlinux.conf after you use jetson-io.py.

Did you install the DSF from the packages or do a manual install?How about the output of these commands:

Thx again for the help -
@hanshogeland It looks like you've done everything right but there are some issues with jetson-io I think.
jetson-io should create the file
/boot/tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtbfrom/boot/tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtboDouble check that there IS a file in boot named
tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtbIn /boot/extlinux/extlinux.conf, the FDT entry should match the file name but it looks like in your conf file there's an extra
kernel_prepended to the name...
FDT /boot/kernel_tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtb
Thekernel_should NOT be there. It should be:
FDT /boot/tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtbThe name itself doesn't really matter as long as the FDT entry points to the correct file.
To use the full dtb I attached, just copy it to /boot/ and make sure the FDT entry points to it.
-
@gtj0
Ok, so I tried to remove the kernel_ prexif and I checked that the dtb exist however it will not boot up using that dtb.
So I am thinking what are controlling or setting the name in the second column in the gpioinfo for pin 13 ( "dcs-trp-13" )? Since I cant find that anywhere in any dtb or dtbo.Thx again
//Hans -
This is really bizarre. I just rebooted a b00 unit with that exact dtb file.
Run...
$ md5sum tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtb bee35cc5ec5f1bb5eaafab30f1fbfea4 tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtbDo you get that same md5 hash?
Try placing the FDT line in the top entry (primary) of extlinux.conf and and remove the whole "Single SPIDEV" at the bottom. Then change the default entry to primary. Your extlinux.conf should now look like this...
TIMEOUT 30 DEFAULT primary MENU TITLE L4T boot options LABEL primary MENU LABEL primary kernel LINUX /boot/Image INITRD /boot/initrd FDT /boot/tegra210-p3448-0000-p3449-0000-b00-single-spidev.dtb APPEND ${cbootargs} quiet root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4 console=ttyS0,115200n8 console=tty0 fbcon=map:0 net.ifnames=0 # When testing a custom kernel, it is recommended that you create a backup of # the original kernel and add a new entry to this file so that the device can # fallback to the original kernel.

" dcs-trp-13" will only get placed there if the DCS can actually open that gpio so that's no big deal.

Thx for you effort, yes it was the same hash - so I take the .DTB and just put in the the boot/ dir and changed the exif to match the one you sent. Still it would not boot. Or do I need to flash?
However I tried again with the single DBTO file and I am thinking since I get the line 19: in the GPIOINFO to match the line 19 of yours with [used], it would be the case that the DBTO is actually read in. So are there any additional changes one could make to enable the line 13 like yours? I tried to look into the pinmux spreasheet however I am not there yet to be near to understand the configuration.line 12: "SPI1_MOSI" unused input active-high line 13: "SPI1_MISO" unused input active-high line 14: "SPI1_SCK" unused input active-high line 15: "SPI1_CS0" unused input active-high line 16: "SPI0_MOSI" unused input active-high line 17: "SPI0_MISO" unused input active-high line 18: "SPI0_SCK" unused input active-high line 19: "SPI0_CS0" "cs_gpio" output active-high [used] line 20: "SPI0_CS1" unused input active-high -
@hanshogeland Sorry! I didn't see your reply until just now.
This is really weird and I do not understand. You do NOT have to flash anything. You'll only get the "dcs-trp-13" and [used] if the duet control server is actually running and successfully opens that pin.
I'm retrying a few things with the latest 32.5.0 release of Linux for Tegra.

@hanshogeland OK, try this dtb...
tegra210-p3448-0000-p3449-0000-b00-user-custom.dtb.stl
I've tested it so it should work. Now I have to clean up all my tries and make sure I can reproduce it.

@gtj0 thx again! to rule out any Duet board issue I tested with a RPI3B+ and it turns out I get an error there also. So I checked the cable, and that seems to be ok. I have reset and flashed the board with the latest firmware - and there was my verry stupid mistake I had not flashed with the correct BOSSA settings! So I flashed it correct and now It’s working on the RPI - I will get back for the result about the Jetson. And thx again for your help!
