Custom compile für arm32bit - no GPS?

Development
1

Hi there!

I’ve a bunch of Raspberry Pi 1 Modell B+ (arm 32bit) around and want to use them for meshtasticd as they have still plenty of resources to do this job.

With some cross compiler work I’ve managed to get a working meshtasticd for arm 32bit which starts and works fine on 32bit bookworm for arm with the Waveshare LORA Hat connected to the Raspberry Pi.

But one thing differs to from the stock debian package for the 64bit platform: there is no GPS. Even in the log I can’t see any GPS messages. config.yaml is fine, serial is enabled and successfully tested one the 32bit Pi, the Hat is sending GPS informations. On the 64bit Raspberry Pi it works perfect.

At the moment it seems that there is no GPS support at all compiled into the binary. On the other hand i can see:

Compiling .pio/build/native/src/gps/GPS.cpp.o
Compiling .pio/build/native/src/gps/NMEAWPL.cpp.o
Compiling .pio/build/native/src/gps/RTC.cpp.o

I’ve tried to add #define HAS_GPS 1 in src/configuration.h and variants/portduino/variant.h but without success.

Maybe this sounds a bit silly questions, but it’s my goal to get this running on the older 32bit arm architecture is it is still sufficient.

Does anyone has an idea?

Can you confirm the gps functioning on the Pi 1 ?

Can you detail/describe this in more detail ?

Oh and also can you post a Meshtasticd bootlog for the working Pi4 GPS ?

Hi Mark,

thanks for getting into this!

When I do a cat /dev/ttyAMA0 I can see that the GPS from the Waveshare HAT is working:

$GLGSV,2,2,06,79,13,230,,69,29,323,,0*74
$GNRMC,084049.000,V,,,,,,,260124,,,N,V*2B
$GNVTG,,,,,,,,,N*2E
$GNZDA,084049.000,26,01,2024,00,00*48
$GPTXT,01,01,01,ANTENNA OK*35
$GNGGA,084050.000,,,,,0,00,6.3,,,,,,*44

My /boot/config.txt has:

enable_uart=1
dtoverlay=uart0

And the config.yaml

### Define GPS

GPS:
  SerialPath: /dev/ttyAMA0

The cross compiler process is a bit complicated. After some fiddling I’ve realized that platformio does not have a arm32 toolchain for debian 64bit. Thus it is not possible to build for the Raspberry Pi 32bit on a 64bit Ubuntu. I’ve ended in getting

onto my Ubuntu system and chroot into that. From here I’ve installed all necessary tools (python3, pip, platformio, lib dev packages, …) and clone the meshtastic firmware git into the chroot arm32v5 environment. From this point I was able to successful compile the native variant for arm32.

And this really works. All the LORA stuff works out of the box on the 32bit Raspberry Pi. Only the GPS thing and/or position module does not show any activity.

At the moment I don’t have the time to switch back to the 64bit Raspberry Pi 3 B+, but will do so as soon I have some time to send you the startup log. But I’m quite sure, that with the deb package meshtasticd does have some GPS messages and tries to connect to the GPS radio via serial.

As requested here is the startup log from the Raspberry Pi 3 B+ with the meshtasticd from the official deb package. All this GPS messages does not appear on my own build arm32 binary. Still wondering if I’ve missed anything in the build process (pio run -e native).

I simply used the 32bit Debian Bookworm OS to build a 32-bit binary for my Pi0W (i cant find my Pi 1)

But my next venture will by looking at possibility of running Meshtasticd Native on MilkV-Duo Riscv64
For this i already have USB input working on MilkV Duo - https://www.youtube.com/watch?v=Swo-zJ6brQI

and found a platform io platform for riscv

But it also just skips any GPS probing detection/check so similar to your Pi1

there is a bug in 2.2.19 related to GPS. Use 2.2.18 instead.

I did a re-compile while you were doing fix - it much quicker to test on Desktop that moving to Pi

Thanks for this tip! But this was not successful. I’ve checkout this tag:

v2.2.18.e9bde80

But during build this error is thrown:

Compiling .pio/build/raspbian/src/input/LinuxInput.cpp.o
*** [.pio/build/raspbian/src/PowerFSM.cpp.o] Error 1

My knowledge in platformio and it’s build process is limited, so I don’t know how to fix that …

In platform.ini line 71 remove the caret ^ after the @ and compile again.
jgromes/RadioLib@6.3.0

Okay, I’ve learned what the “^” before a version number means :smiley: Thanks!

Thank you!!! GPS is now working on latest master variant native on my 32bit Raspberry Pi :hugs:

15

could you kindly confirm the output of running file on your compiled binary

file program

I’ve compiled the latest master with variant native. The file information:

pi@raspberrypi:~/meshtastic/native $ file program 
program: ELF 32-bit LSB pie executable, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux.so.3, BuildID[sha1]=90c016eff3dce290fee288b64343e6e702c4709a, for GNU/Linux 3.2.0, with debug_info, not stripped

But I must admit that I have to copy the library folder from my build rootfs, which is arm32, to the Pi and add the folder to

/etc/ld.so.conf.d/meshtastic.conf

I don’t know why but the binary does not accept the already installed libraries despite they look the same. This is a mystery to me.

Copied library:

pi@raspberrypi:~/meshtastic $ file arm-linux-gnueabi/libgpiod.so.2.2.2 
arm-linux-gnueabi/libgpiod.so.2.2.2: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=d5667287d4e4a1022685853e8ee6a4f29c1da89e, stripped

Versus system library from the Pi distribution:

pi@raspberrypi:~/meshtastic $ file /usr/lib/arm-linux-gnueabihf/libgpiod.so.2.2.2
/usr/lib/arm-linux-gnueabihf/libgpiod.so.2.2.2: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=d3d124faa2da23615dc352e9d8ca8dcb938b8641, stripped

Hope this helps!

I simply used the 32bit Debian Bookworm OS to build a 32-bit binary for my Pi0W (i cant find my Pi

Confirmed sing the 32bit Raspberry Pi OS Bookworm produces a compatible binary that will run on Pi zero

Pi zero and Pi 1 both use same archiecture cpu

I’ll try the same the next days … maybe then I don’t need to copy the libraries from the build system to the target system …

Is this an Intel/AMD x86 system with a 32bit Debian Bookworm?

No using Raspberrypi
