error

Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again...

Com port selected correctly, switches Boot 1 - 0, Boot2 - 0 Pressing reset at the time of upload does not trigger the upload process? Please help Regards

Hi @qulet, I found a video explaining some reasons why this may happen: https://www.youtube.com/watch?v=Rr0tNVy2geg

And someone with a similar issue: https://community.st.com/t5/stm32cubeprogrammer-mcus/cubeprogrammer-connect-to-uart-interface/td-p/290057

I will admit when I first tried doing this, I had to play around with the 2 boot switches a bit until I got it working. Also, maybe a board might need a lower baud rate to talk properly?

Let me know if these help!

Thank you very much for your tips and help. Now the STM32CubeProgrammer connects to the yellow board. I have uploaded the compiled Bills_iCubeSmart.ino.hex file. The 8x8x8 LED.exe program connects to COM4 but the LEDs do not light up. I tried to re-upload the "icubesmart" Update.hex file, but it also stopped working with the motherboard. Currently, after these attempts, I am in despair because the 8x8x8 RGB cube does not light up. I am sending the programming log. What am I doing wrong ?

p.s I couldn't program the yellow board using the Arduino IDE, so I found a compiled .hex file and uploaded it to STM32CubeProgrammer.

Hex

When uploading a hex file BOOT0=1 BOOT1=0 it worked. After uploading the hex file BOOT0=1 BOOT1=1

Attempting to upload the Release/// Original Firmware 8x8x8 RGB Cube.hex file causes an error: error parsing Regards

breaking news! Successfully uploaded the program from the Arduino IDE. BOOT0=1; BOOT1=0

Arduino_IDE

After uploading, I set the switch BOOT0=0 BOOT1=1. Three diodes green, red and blue lit up on the yellow board. Serial port conect - Send TestPacket does not work. The diodes do not light up. When I disconnect USB-TTL from the computer, the LEDs RGB light up for a moment. Changing BOOT1=0 and reconnecting the USB-TTL to the computer port also does not cause the LED to light up after pressing the Send TestPacket button. Baud Rate = 2000000, 38400 all With USB-TTL plugged in, removing the cube power cable causes the LED RGB to light up momentarily.

After pressing the send button, the LEDs on the USB-TTL interface start pulsating but the RGB LEDs do not light up

kostka My motherboard is a new version, maybe this is the cause of the problems? PCB PCB_1 After assembly, the cube worked on the loaded Icubesmart firmware. An attempt to restore the firmware with their software was unsuccessful. I did it with STM32CubeProgramer with the Update.hex file but the cube stopped working, I don't know what to do next?

@qulet I think the problem you're facing is that your cube is not getting enough voltage. In my case, I had to make a custom wire to provide enough voltage (5 volts, 2 amps) to the board. In the below photo, the circled blue is the voltage for the LEDs, and the circled green is the USB data +/- connectors. You could just use a separate power source for the LEDs, but I liked having 2 in 1 so I only have to deal with 1 cord: signal-2023-09-27-001102

Thank you for your answer ! My cube is powered by a 5V-2A phone charger and the icubesmart software works well. I managed to upload the botloader (I got the file from the icube smart service), which I deleted while trying to use your software. The cube currently runs on the original firmware.

@qulet can you share the bootloader file so I can add it in case anyone else gets stuck and needs it?

qulet commented 1 year ago

Icubesmart firmware upload STM32CubeProgrammer. After uploading the bootloader, you need to upload update.hex with a dedicated software

https://github.com/Sliicy/8x8x8-LED/blob/master/Firmware/RGB/Original%20Firmware%208x8x8%20RGB%20Cube.hex It isn't the same as the one I have in my repo but thank you.

You have a different motherboard, mine has a built-in microphone, I think this is the reason for the difference in the bootloader code. Generally, this is probably why your "Bills_iCubeSmart.ino" code doesn't work. The 8x8x8 LED.exe program seems to be OK, because the transmission diode on the USB-TTL interface blinks at a speed proportional to the "speed" slider settings Regards!
