|
|
|
|
|
- Download and install the version 1.6.9 of the Arduino IDE:

|
|
|
|
https://www.arduino.cc/en/Main/OldSoftwareReleases#previous
|
|
|
|

|
- Build the firmware with bootloader support:
|
|
|
|
|
make bl
|
|
|
|
|
|
|
|
|
|
- Upload bootloader and firmware to ZUMSpot USB board, using serial port first (you
|
|
|
|
|
are using an USB-serial converter with device name /dev/ttyUSB0):

|
|
|
|
|
|
|
|
* Linux:
|
|
|
|
|
coming soon...
|
|
|
|
|
Hold BOOT0 (or move BOOT0 jumper to 1), next press and release RESET
|
|
|
|
|
|
|
|
|
|
sudo make serial-bl devser=/dev/ttyUSB0
|
|
|
|
|
|
|
|
|
|
Release BOOT0 (or move BOOT0 jumper to 0)
|
|
|
|
|
|
|
|
|
|
- For following firmware updates, you could use the USB port directly:
|
|
|
|
|
sudo make dfu devser=/dev/ttyACM0
|
|
|
|
|
|
|
|
|
|
* Install MMDVMHost:

|
|
cd ~
|
|
|
|

make
|
|
|
|
|

|
nano MMDVM.ini
|
|
|
|
|
(use Port=/dev/ttyACM0 in [Modem])
|
|
|
|
|
|
