No communication with NRF24L01 on RPi3 64bit [SOLVED]
-
Hi!
Just recently discovered MySensors and this is what I was looking for!
Unfortunately I can't get communications my RPI3 to communicate with a NRF24L01.My setup: RPi3 with a custom kernel 4.13.16 using 64bit, with loaded kernel module spi_bcm2835.
$ uname -r 4.13.16-v8+ $ cat /boot/config.txt [...] dtparam=spi=on $ lsmod [...] spi_bcm2835 20480 0 $ ls /dev/spidev0.* /dev/spidev0.0 /dev/spidev0.1I use the dev-branch (also tried stable, same behavior):
$ ./configure --prefix=/data/home/gunther/mysensors --my-transport=nrf24 --my-gateway=ethernet --my-port=5003 [SECTION] Detecting target machine. [OK] machine detected: SoC=unknown, Type=unknown, CPU=aarch64. [SECTION] Checking GPIO Sysfs. [OK] /sys/class/gpio/export found [SECTION] Detecting SPI driver. [OK] SPI driver detected:SPIDEV. [SECTION] Detecting init system. [FAILED] unknown init system. [SECTION] Saving configuration. [SECTION] Cleaning previous builds. [OK] Finished.The unknown init system should be fine, as I do not want to create any startup scripts or move files somewhere.
Running the gateway as root gives:
$ ./bin/mysgw -d mysgw: Starting gateway... mysgw: Protocol version - 2.2.1-alpha mysgw: MCO:BGN:INIT GW,CP=RNNGL---,VER=2.2.1-alpha mysgw: TSF:LRT:OK mysgw: TSM:INIT mysgw: TSF:WUR:MS=0 mysgw: !TSM:INIT:TSP FAIL mysgw: TSM:FAIL:CNT=1 mysgw: TSM:FAIL:DIS mysgw: TSF:TDI:TSLThis tells me that the communication between radio and RPI fails.
I (more than) triple-checked the wiring.
I use a voltage regulator from 5V to 3.3V and have a 47µF capacitor between GND and 3.3V. I also tried a different voltage regulator and NRF24L01.I assume the radio itself should be fine because attached to a Arduino Nano (with voltage regulator, without condensator) I see:
16 MCO:BGN:INIT NODE,CP=RNNNA---,VER=2.2.0 25 TSM:INIT 26 TSF:WUR:MS=0 33 TSM:INIT:TSP OK 35 TSM:FPAR 37 TSF:MSG:SEND,255-255-255-255,s=255,c=3,t=7,pt=0,l=0,sg=0,ft=0,st=OK: 2046 !TSM:FPAR:NO REPLYWhich I expect to the missing gateway.
-) Is the SPIDEV driver ok? BCM does not compile for 64bit.
-) Do I need to activate any GPIO ports with
echo "$i" > /sys/class/gpio/exportor anything alike?
-) Is it ok, that I use other GPIO ports directly for other things?
-) Is there a way to test that SPI is working properly?Thanks!

@gunther After fighting with this problem for some days, I now got it working. The solution was to use the BCM driver instead of SPIDEV.
I achieved that by commenting out the 32 bit gcc flags in ./configure
function gcc_cpu_flags { local soc=$1 case $soc in BCM2835) flags="-march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp -mfloat-abi=hard" ;; BCM2836) flags="-march=armv7-a -mtune=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard" ;; BCM2837) flags="" #flags="-march=armv8-a+crc -mtune=cortex-a53 -mfpu=neon-fp-armv8 -mfloat-abi=hard" ;;and running configure with this options:
$ ./configure --my-transport=nrf24 --my-gateway=ethernet --my-port=5003 --soc=BCM2837Hope this shortens the learning curve for 64bit Rasperry Pi users!
