I have a big problem. I have one Alexmoss 32 bits in plastic case, but I connect with PC and I upgrade firmware bad and now I can not connect with the program.
What is the solution? Can I restoring the firmware? How it´s made?
Hello, The User Manual have a subsection (in the section 13. Firmware update): Uploading firmware in the manual mode. This option is intended for special cases when the board becomes bricked (GUI cannot connect to it) and you need to upload special a “recovery” version of firmware, or when you experienced problems with automatic upgrade. Use this mode carefully and only if you understand what you are doing! 1. Disconnect any power source and USB cable. 2. Close (set) FLASH jumper on board (attach jumper to the 2 pins marked as 'FLASH', thus 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 but 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 32-bit board • v.3.x (32bit) through USB in DFU mode – for a “Tiny” type 32-bit version 7. Press "FLASH" button and wait for process to finish. 8. Open (remove) FLASH jumper.
Hello, Congratulations! Now, you need unplug all power sources from the board (USB and battery) and open flash jumper. After, connect control board to the PC and upgrade board in Automatic mode to desired firmware version.
Yes I make the same that you said me, but when I disconnect the board and connect again I can not connect with GUI. For exampel, I put 2.42b7 firmware and I use GUI 2.42b7 adn I update firmware automatic and all is ok. But now disconnect the board of USB and battery and connect again to programm and the board only lights LED red and I can not connect with GUI. I have not idea what is the problem.
Good. At first I could do everything as you stated in the manual and there were no problems. Today, when you connect the board to the PC and start the gui, everything was a mess, and does not recognize or can you re-install the firmware manual or automatic winding mode.
