Is MySensors RPI GW 32bit only?

[joaoabs]

Apologies if this is a repeated thread.
I've been trying to compile a MQTT GW for my 64bit RPI4 but I'm getting some errors that seem to be related with the 64bit arch I'm using.

I'm currently preparing a RPI4 for a IOT stack with docker containers and I believe using the RPI4 64bit capability would be useful to have a performant system.
(by the way, it would be great to have a forum topic teaching how to create a docker container with the MySensors GW, but that would be for another time).

Anyway, back to my issue, below the steps I've taken. I've tried master and development branches. Is there any way of making this work in 64bits or am I doing something wrong?

Cheers,

[joaoabs]

Answering my own post with info from this post from 2018 and adjusting to my chipset (BCM2711), I commented the flags. Not sure what I'm doing, but at least the error is not the same anymore.

function gcc_cpu_flags {
    local soc=$1
    case $soc in
    BCM2835)
        flags="-march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard"
        ;;

        #flags="-march=armv8-a+crc -mtune=cortex-a72 -mfpu=neon-fp-armv8 -mfloat-abi=hard"
        ;;

Moving on to the next error.

The gateway is not intentionally 32-bit only. You're probably just the first person who tries to make it work on 64-bit.

[joaoabs]

I admit I'm not a programmer neither a computing expert.

But this article here says that "Generally speaking, 32-bit programs can run on a 64-bit system, but 64-bit programs will not run on a 32-bit system."

My understanding is that if I compile MySensors GW in a 32bit RasPI OS and copy & run it on RasPI 64bit OS it will likely work (I'm guessing I'll also have to copy some libraries, so not so simple as copying the binary).
This can be the option for those who want to use MySensors in 64bit RPIs like myself. I'll be using IoTStack on a RPI4 4GB 64bit with zigbee2MQTT and honestly wasn't happy with the idea of having a second RPI just for MySensors GW.

I'll try it during the weekend and share results here.

[joaoabs]

So I managed to successfully run MySensorsGW in a RPI4 with 64bit OS, based on the theoretical premise that a 32bit binary can run in a 64bit system.

My project idea is to have a central device running my house automation. For that, I use and RPI4 4GB with IoT stack witch is a set of docker images each one with a specific function. This way, I'll be running MQTT Mosquito, NodeRed, zigbee2MQTT, inFluxDB and Graphana, each one in its own docker container. IoT stack also includes other images like transmission torrent, nextcloud, PiHole, etc. I might also use some of it later on.
Anyway, all of this requires a lot of effort from the little RPI4 so it is important to be able to use all of its resources. Using a 64bit OS is one way to have a more performant system and to be able to address all the RAM (4GB in my case).

So, having mysgw in this RPI was crucial to maintain a small footprint. It would be great to have the MySensors GW as a docker container as well, but for now this workaround would have to sufice.

Compiling mswg in RPI 64bit OS is not working (as per the above), but compiling it in a 32bit RPI OS and then copying a couple of files to the RPI 64bit OS it works, at least in my case. My msgw is configured as a MQTT GW, so if yours is different, your millenage may vary.

./configure --my-gateway=mqtt --my-controller-ip-address=192.168.2.180 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=MySensorsGW --my-transport=rfm69 --my-signing=software --my-signing-request-signatures --my-rfm69-frequency=433 --my-is-rfm69hw --my-signing-debug --my-rfm69-encryption-enabled --my-mqtt-user=mysensorsuser --my-mqtt-password=mysensorspassword

(Now I can change the --my-controller-ip-address to 127.0.0.1. This way, if for some reason I want to change the controller IP address, I'll not need to re-compile)

Anyway, so the process is basically compiling everything in the 32bit RPI OS, (configure, make, sudo make install), configure the /etc/sensors.conf accordingly and then coping these files to the same path in the 64bit RPI OS:

/usr/lib/arm-linux-gnueabihf/libstdc++.so.6
/etc/mysensors.conf
/etc/systemd/system/mysgw.service
/usr/local/bin/mysgw 

Run it as normal:

sudo systemctl start mysgw.service

Enjoy

FYI I was able to get the gateway to work properly on a 64 bit Raspberry pi 400 machine.

I'm not sure if it's required, but installing the bcm2835 v 1.68 (that includes an earlier patch for pi 4) may have helped along with removing the bcm2711 flags from the configure file.

I will plop a radio in this weekend and see if it still works.

[fixjunk]

Just a small addendum...

I tried swapping my Pi3B+ install into a Pi 400 with the BCM2711 and it did not work.

I needed both the BCM2835 v 1.68 and to remove the flags from the "configure" script BCM2711 section.

[Dmitry Cherkas]

To anyone, who will come here searching for a way to compile MySensors Gateway on 64bit OS, here is how I managed to do that on Ubuntu Server 20.04:

ubuntu@ubuntu:~ $ cat /proc/cpuinfo | grep Model && uname -a
Model           : Raspberry Pi 4 Model B Rev 1.4
Linux rpi-ubuntu-server 5.4.0-1034-raspi #37-Ubuntu SMP PREEMPT Mon Apr 12 23:14:49 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux

1. Make sure to use development branch(git clone https://github.com/mysensors/MySensors.git --branch development), otherwise you may face fatal error: stropts.h: No such file or directory [1], which is not fixed in master branch.
2. As I understood from [2] and [3], unrecognized command line options (-mfpu=neon-fp-armv8 -mfloat-abi=hard) are not valid for ARMv8 AArch64 targets, so it's safe to remove them. I did that by updating ./configure as follows (in my case soc=BCM2711, so I left others intact):

function gcc_cpu_flags {
    local soc=$1
    case $soc in
// ...
    BCM2711)
        flags="-march=armv8-a+crc -mtune=cortex-a72"
        ;;
// ...
}

1. With above setup I was able to build Ethernet Gateway:

/configure --my-gateway=ethernet --my-port=5003 --my-transport=rf24 --my-rf24-irq-pin=15 --soc=BCM2711

[Dragos Pascale]

in hal/transport/RFM69/driver/new/RFM69_new.h you must also replace
#define RFM69_MAX_PACKET_LEN (0x40u) with
#define RFM69_MAX_PACKET_LEN (0x40ul)
if you are using RFM69 radio

[joaoabs]

@Dragos-Pascale said in Is MySensors RPI GW 32bit only?:

in hal/transport/RFM69/driver/new/RFM69_new.h you must also replace
#define RFM69_MAX_PACKET_LEN (0x40u) with
#define RFM69_MAX_PACKET_LEN (0x40ul)
if you are using RFM69 radio

@Dragos-Pascale Why that change? What is the behavior if you don't do it?

[joaoabs]

@joaoabs Got it. It doesn't compile if we don't replace the RFM69_MAX_PACKET_LEN (0x40ul)

And I can confirm that the procedure above worked. Compiled directly in a RPI4 with 64bit OS.

[suspendfunction]

Anyone tried this with RFM69HCW?

I got it compiled on Arch Linux ARM with the aarch64 linux-rpi kernel after editing ./configure and hal/transport/RFM69/driver/new/RFM69_new.h as described above.

I have built commit aa520cea, the latest from the development branch, using this config:
./configure --my-gateway=ethernet --my-transport=rfm69 --my-is-rfm69hw --my-rfm69-frequency=868 --extra-cxxflags="-DMY_DEBUG_VERBOSE_RFM69 -DMY_DEBUG_VERBOSE_RFM69_REGISTERS"

My hardware should be fine, i didn't change anything and it was working with the 32-bit kernel before.
