With this procedure your transceiver will self boot/extract/flash the software for both main board (MB) and front panel (FP) micro controllers. Needed are only PC and USB cable (type A at one side; type B at other side). When turned in flash mode (menu 37) RGO ONE USB adapter works as a Mass storage device and would appear on your computer as a hard disk (removable hard drive with 256kByte of memory). This way your RGO would store needed dfu files and after checking them would self update its FP/MB micro controllers. No other SW tools are needed!
VERY IMPORTANT: Use stable and reliable power source 13.8V. During flash update power supply must not be interrupted. If power supply dropped micro processors would die and can be revived again only with dev programmer via system JTAG connectors located on FP and MB boards.
Here are the steps to perform FW flash update:
1. Save on your Personal Computer (PC) new FW files from Downloads section of www.lz2jr.com.
2. Create a folder RGO ONE on your desktop. Extract archive file in a folder RGO ONE on your PC. You will see two dfu files.
3. Connect USB cable between transceiver and your PC.
4. Enter menu 38 FLASh and set menu parameter to YES.
5. Exit the menu with long press of MTR MNU button.
6. Green LEDs TX/ALC and RIT/XIT will start blinking. UPLOAD label is shown on LCD! At this point you can go on with next step or if you decide not to perform flash update – just switch off the radio. Then switch on and it will start in normal mode.
7. On the screen of your PC – a new removable hard drive called RGO ONE will appear. If the window RGO ONE does not pop up check the disk in “My computer” icon on your PC. When you find RGO ONE disk – it must be blank with no files on it. If there are old files on it already written – delete them.
8. Drag and drop (copy) both MB and FP dfu files already prepared on your PC to this removable disk. Wait enough time for the file transfer between your PC to RGO ONE. Then you will see two files written in RGO ONE removable disk named CPU_rgo_one.dfu and MB_rgo_one2.dfu.
9. Cycle OFF and ON the radio.
10. TX/ALC and RIT/XIT LEDs will start glow in red. LCD shows “Flashing”. (If the radio starts without flashing then files are not proper format dfu files or wrong version!). It takes a minute to complete FW upload. Ensure stable power supply and do not turn off the power supply! After successful flash update the radio turns on in normal operation.
11. After successful flash update menu 37 will show new software version. If software version in menu 37 is blinking then some of the files failed to upload and FLASH procedure must be repeated again.
