compilation for M17 mode fails

[acfnews]

Hi Steve,

I am having issues compiling the firmware for the STM32_DVM (pihat v3) and new M17 mode.

I followed your instruction as described in the steps, but there are two issues:

• with the master branch I can compile, and a hex file is compiled and can be programmed on the modem, but the MMDVMHost is not able to use it: E: 2021-05-16 11:53:27.781 Unable to read the firmware version after six attempts
• with the M17_AX25_FM branch, following the same instruction, I get this error:

  MMDVM# make -f Makefile.CMSIS
  make: *** No rule to make target 'SampleRB.h', needed by 'obj/DMRDMOTX.o'.  Stop.

If you have a bit of time to have a look ?

Best regards,

Ron

Ron, For the V3 board: make clean make dvm

Steve, thanks!
With that it does compile! It will make some testings with that file the coming days!

Hi Steve,

I have restarted my investigations. Our remote repeater was running PI-star, and we decided to get rid of that, and just compile the stuff ourselves on top of RasperryOS. Yesterday we reinstalled the OS (remote site, difficult to enter), and now I am trying to get things working again remotely.

I am succeeding in building both the MMDVMhost, and MMDVM firmware binaries, and program the STM32. So far so good. I am using the branch 'M17_AX25_FM'

However, the firmware(s) I create, doo not seem to work for the digital modes. No response in either log file or repeater function. Analog FM does work. The digital modes do work when using an older (FM) firmware, so I do have a solid reference point.

Using the self-build firmware, the following is printed in the log, which seem quite OK:

I: 2021-06-15 10:30:47.180 MMDVM protocol version: 2, description: MMDVM RB_STM32_DVM(446) 20210508 12.0000 MHz GitID #43b53fe
I: 2021-06-15 10:30:47.180 CPU: ST-Micro ARM, UDID: 390020001151373436383037
I: 2021-06-15 10:30:47.180 Modes: D-Star YSF NXDN M17 FM

Now I have some questions, to verify I am not missing something: 1) From this GitHub repo (MMDVM-Install/STM32) I have installed all the packages as described in 'required-libs.sh'. Without them, compilation does fail. I expect this is still an up-to-date procedure.

2) I did not install the stm32cube_fw_f1_v140.zip files in ./opt as described in 'get-src.sh' Compilation does not complain about missing items, or might this be a reason why my firmware is not working?

3) Last there are 2 files, which I guess are specific for the STM32 PIHat I guess: SerialRB.h and Config.h

There are some new items in the original Config.h (eg. #define MODE_xxx, and #define SERIAL_SPEED) My Config.h looks like:

$ cat Config.h | egrep -v ^'(\/\/|^$)' /*

  define CONFIG_H

  define MODE_M17

  define MODE_FM

  define USE_COS_AS_LOCKOUT

  define ARDUINO_MODE_PINS

  endif

I have attached my compiled firmware version.

Could you have a look if my described steps are correct, and if on your side compiling the same set produces the same, or a different firmware file?

This is for the Blue board, v3 version.

Many, many thanks in advance,

Ronald

Steve,

I have a bit more success, I have succeeded in building the following working combinations (branches) of firmware/software:

• FM
• M17

Both have a working YSF and Analog function (I cannot test other digital modes)

However, when building M17_AX25_FM, I am loosing the Analog repeater function.

Starting the mmdvmhost shows:

I: 2021-06-19 19:22:58.619 MMDVM protocol version: 2, description: MMDVM RB_STM32_DVM(446) 20210617 NO TCXO GitID #f4e1c0b
I: 2021-06-19 19:22:58.620 CPU: ST-Micro ARM, UDID: 390020001151373436383037
I: 2021-06-19 19:22:58.620 Modes: D-Star DMR YSF P25 NXDN M17 FM POCSAG AX.25

Not sure where this goes, wrong, at least I do have some better confidence in how to build both the firmware/software.

Would you be willing to give this branch a quick test? My resulting hex file has sha256sum : 700f0b8602fedcf109db06e41777515c51bf080d146554b3bc67ee8e164f3e65 bin/mmdvm_f4.hex

Steve, the Config.h file is quite different in the M17_AX25_FM branch. Also the speed is increased : #define SERIAL_SPEED 460800

Any feedback is appreciated !

Ron, My testing is done with the M17_AX25_FM branch of both MMDVM and MMDVMHost For the serial speed I'm testing at 460800 since most people will want FM networking.

It's working now! Just build the latest firmware and host software.
