ZumRadio-MMDVM firmware update?

Post by N6MIK » Sun Jul 15, 2018 3:58 pm

Hi all,

I tried to update the firmware using "sudo pistar-mmdvmhshatflash rpi_duplex"

After completing, and power cycling, the modem still reports the original firmware version (MMDVM:20170501)

I must be missing something - any thoughts?

If it is a zumradio , You are trying to update it with the firmware for a hotspot...This is what you need to do to get the correct firmware into the ZumRadio...Disregard if this is a ZUMSPOT

Installation of necessary software (only once)

If you are using Pi-Star, expand filesystem (if you haven't done before):

sudo pistar-expand
sudo reboot

Enable RW filesystem if you are using Pi-Star:


Update list of packages:

sudo apt-get update

Install toolchain and necessary packages:

sudo apt-get install git gcc-arm-none-eabi gdb-arm-none-eabi libstdc++-arm-none-eabi-newlib autoconf libtool pkg-config libusb-1.0-0 libusb-1.0-0-dev

Download and compile serial flashing utilities:

cd ~
git clone https://github.com/jsnyder/stm32ld
cd stm32ld
sudo cp stm32ld /usr/local/bin

Remove libi2c-dev and stm32flash packages if you are using Pi-Star:

sudo apt-get remove libi2c-dev
sudo apt-get remove stm32flash

Install the latest stm32flash:

cd ~
git clone https://git.code.sf.net/p/stm32flash/code stm32flash
cd stm32flash
sudo make install

Another place to get the lastest stm32flash is:


MMDVM firmware compilation and uploading for MMDVM-Pi

Download firmware sources:

cd ~
git clone https://github.com/g4klx/MMDVM
git submodule init
git submodule update

Edit Config.h according your preferences:

nano Config.h

You can select for example:

// #define EXTERNAL_OSC 12000000 (disable any external TCXO)
// #define ARDUINO_DUE_ZUM_V10 (this option doesn't matter for STM32 devices)
#define MODE_LEDS


make pi

If you are using Pi-Star, stop services:

sudo pistar-watchdog.service stop
sudo systemctl stop mmdvmhost.timer
sudo systemctl stop mmdvmhost.service

Upload the firmware:

sudo make deploy-

The very last command should be

sudo make deploy-pi

Is this the latest "how to" to update the Zum Radio firmware. I have one set up as a dmr hot spot but when connected to TG9990 I can transmit but I don't get an echo also PTT Led not operating so not at the "invert tx audio or invert PTT stage . Firmware is 20170501 Pi-Star v20181220 . any other ideas welcome .
