Failed to start the concentrator with kernel 6.6.22 (Pi 4B Bookworm + SX130X)

[timiman]

I'm unable to start a SX130X as concentrator under kernel 6.6.22 on a Pi 4B.
Running reset_lgw.sh, outputs:
./reset_lgw.sh: 26: echo: echo: I/O error ./reset_lgw.sh: 27: echo: echo: I/O error ./reset_lgw.sh: 28: echo: echo: I/O error ./reset_lgw.sh: 29: echo: echo: I/O error ./reset_lgw.sh: 32: cannot create /sys/class/gpio/gpio17/direction: Directory nonexistent ./reset_lgw.sh: 33: cannot create /sys/class/gpio/gpio22/direction: Directory nonexistent ./reset_lgw.sh: 34: cannot create /sys/class/gpio/gpio18/direction: Directory nonexistent ./reset_lgw.sh: 35: cannot create /sys/class/gpio/gpio13/direction: Directory nonexistent CoreCell reset through GPIO17...

By default the reset GPIO pin was pointing to 23, but found that 17 is the correct one for this SX130X.
It seems like the GPIO number has changed for 6.6.22 , as I'm getting:
grep -s . /sys/class/gpio/gpiochip*/* /sys/class/gpio/gpiochip512/base:512 /sys/class/gpio/gpiochip512/label:pinctrl-bcm2711 /sys/class/gpio/gpiochip512/ngpio:58 /sys/class/gpio/gpiochip570/base:570 /sys/class/gpio/gpiochip570/label:raspberrypi-exp-gpio /sys/class/gpio/gpiochip570/ngpio:8

User running all above is in group 'gpio'.

Does the reset_lgw.sh needs changes to work with new GPIO numbering ?

[wildekek]

Just for confirmation: I just ran into the same issue.
[Edit] Seems like GPIO sysfs is deprecated and superseded by libgpiod. We can make a patch to fix the sysfs paths for now, but support for this will likely end in the near future.
https://waldorf.waveform.org.uk/2022/the-one-where-dave-breaks-stuff.html

[timiman]

I've seen that article too.
I've also sent a tech support to waveshare.

[wildekek]

Looks like it is fairly trivial to use the gpiod command line tools for the reset script:
https://manpages.debian.org/experimental/gpiod/index.html

I'll give that a go and let you know if that fixes everything.

[wildekek]

I think that this repo should be marked as deprecated.

I switched to Basic Station using this repo which supports libgpiod.

working docker-compose example for your convenience:

services:

  basicstation:
    image: xoseperez/basicstation:latest
    container_name: basicstation
    restart: unless-stopped
    privileged: true
    network_mode: host      # required to read main interface MAC instead of virtual one
    environment:
      MODEL: "WM1302"
      DEVICE: "AUTO"
      USE_LIBGPIOD: 1
      RESET_GPIO: 17
      POWER_EN_GPIO: 18

I think it misses GPS support which Waveshare's SX130X includes in its hardware implementation

[mcoracin]

Hello,
This issue will be addressed with the next release of this repo, sorry for the inconvenience. :/
Thanks for the feedback.

[KonRoz]

Is there any fix for the time being?

[mcoracin]

@KonRoz for now nothing official, but in the meantime you can check what has been done here:
https://github.com/xoseperez/basicstation-docker/blob/master/runner/reset.sh.gpiod

From a quick test I've done, it seems to reset correctly now, by using the following values for a Waveshare SX130X board on a RPi4 w/ 6.6.28 Kernel:
GPIO_CHIP="gpiochip0"
RESET_GPIO="23"
POWER_EN_GPIO="18"
POWER_EN_LOGIC="18"

[davidgs]

I'm also hitting this problem on a Pi 4. Looks like this repo hasn't had a release in 3 years, and isn't being actively maintained. Is there a better solution? I'd rather not go the Docker route.

[mcoracin]

Hello,
I am currently looking into this. I'll post here a new reset_lgw.sh script for gpiod usage to unblock until the release is done.
For the later release, I was thinking about making the reset.sh script configurable through the command line, so that one can use the sysfs one of the gpiod one depending on its setup.

[timiman]

That's good news. Although Lora is working just fine on TTN v3, it seems that its GPS cannot return valid data even under clear and direct sky, always while running packet_forwarder. It logs:

### [GPS] ###
# Valid time reference (age: 0 sec)
# no valid GPS coordinates available yet

Maybe this issue should also be checked if it has been broken too, due to newest kernel of Linux ?

[mcoracin]

Hello all,
Please find attached an updated reset script using gpiod.
I've quickly tested it on a Raspberry Pi 4.
@davidgs let me know if it fixes your issue.

Best regards,
Michael

[mcoracin]

@timiman I'll check the GPS on RPi4 too

[davidgs]

At least on my RPI4, with a WM1302, no.

[mcoracin]

@davidgs which version of the WM1302 do you have exactly (seeed product reference) ?
Are the GPIOs correct for your setup ?
SPI is properly configured on your RPi ?

[mcoracin]

@timiman I've tested the GPS on my RPi4, and I see no issue, it is working as expected for me.

What do you get when you do a "cat /dev/ttyS0" ?

Have you enabled the serial interface, and modified the /boot/firmware/cmdline.txt to free the serial0 ?

[timiman]

Serial Port is enabled.

With "sudo cat /dev/sttyS0" I get fast scrolling text with ( hide/altered with ##'s location data ):

Also, if I run packet_forwarder and try the python GPS example,
packet_forwarder shows endless scrolling of text, "WARNING: [gps] read() returned value 0",
because of the conflict of accessing GPS from two applications at the same time, I guess.

Finally, the baud-rate of the serial port from python example above is set to 9600.
Maybe the baud-rate is different on packet-forwarder ?

[mcoracin]

@timiman I've never used the Waveshare board, but I've ordered one to test.

What do you get if you do "cat /boot/firmware/cmdline.txt" on your RPi ?

The baudrate is the same as what is used by the hal to configure the serial port:

sx1302_hal/libloragw/src/loragw_gps.c

Line 58 in 4b42025

#define DEFAULT_BAUDRATE B9600

Maybe you could create a separate issue for this, it is quite different from the initial issue reported here. :)

[timiman]

cat /boot/firmware/cmdline.txt gives:
console=tty1 console=serial0,115200 root=PARTUUID=0a5e2d69-02 rootfstype=ext4 fsck.repair=yes rootwait quiet splash plymouth.ignore-serial-consoles cfg80211.ieee80211_regdom=GR

[mcoracin]

Could you try to remove the console=serial0,115200 from this file ?
This was already required to be removed on previous RPi versions, it creates a conflict on /dev/ttyS0 access.
This should allow the packet forwarder to read the output of the GPS.

No change. Same message. I will open a new issue.

[mcoracin]

@timiman even after a reboot of the RPi ?
When opening the new issue, could you indicate :

• the exact hardware you are using
• the RPi config you did to enable the serial interface and the /boot/firmware/cmdline.txt change
• the logs of the packet forwarder startup
  thanks !

[davidgs]

@davidgs which version of the WM1302 do you have exactly (seeed product reference) ? Are the GPIOs correct for your setup ? SPI is properly configured on your RPi ?

WM1302
Model #WM1302-SPI-EU868-M
SPI is set up properly, and the Pins are correct (as best I can tell)

GPIO_CHIP=gpiochip0
GPIO_PIN_SX1302_RESET=17     # SX1302 reset
GPIO_PIN_SX1302_POWER_EN=18  # SX1302 power enable

GPIO_PIN_AD5338R_RESET=13    # AD5338R reset (full-duplex CN490 reference design)

[davidgs]

I have gotten it working. The problem was that I was not using a Pi HAT. I was trying to use the card directly via the M.2 slot on our board, which it turns out does not have access to any of the Pi-header pins.

Ok, good news. :)
So the script that I shared is working for you, right ?

Also thx from over here.

Created a RPi CM4 test setup a couple of days ago and immediately got stuck
due to this obsolete pin control issues.

Thx for sharing; exactly what I needed. A true time saver :)
