Hi, i have a new original Board. But only the red LED is solid after connect to USB. I can't connect. I cant Update Firmware. when i plug it in to USB i can see COM Port 13 is comming up in device Manager.
do i Need to force a Firmware update? how can i do it? thanks
there are instructions in the manual for recovery. For the 32bit version you can find it on page 38 of the manual. I am not sure about 8bit. maybe it's the same?
1. Disconnect any power source, USB cable. 2. Close (set) FLASH jumper on board (attach jumper to 2 pins marked as 'FLASH', shorting them) 3. Connect board to PC by USB cable 4. Run GUI, select COM port (but don't connect!) and go to "Upgrade firmware" - "Manual" tab DO NOT PRESS "CONNECT" IN THE GUI, IF JUMPER IS CLOSED! If pressed, you need to repeat all steps from the beginning. 5. Choose firmware file (*.hex or *.bin format). 6. Select board version: • v.3.x (32bit) through Virtual COM Port – for a regular 32bit board • v.3.x (32bit) through USB in DFU mode – for a “Tiny” 32bit version 7. Press "FLASH" button and wait for process to be finished. 8. Open (remove) FLASH jumper.
