Firmware Problem?

Caruizdiez · July 12, 2024, 5:22pm

Hi forum, yesteerday. I had a problem, and maybe you could help me, Here’s what happened:

Yesterday, I was working with it when my colleague moved the PCB (SKR pro) and possibly removed the micro SD card in the middle of the machine’s operation. The machine stopped, and now I can’t establish communication between it and my computer. I’ve been searching for information on the website, but I still have some questions.

My main question is whether removing the SD card could have damaged the machine’s firmware. Is the firmware loaded on the SD card? Or is it stored directly in internal memory on the SKR? I bought the microSD card from V1 store, and now when I open it, it’s empty. Is this normal?

It seems to me more like a software issue (communication problem, as the touchscreen also doesn’t recognize the SKR) rather than a hardware component failure. Right now, I am in Chad (Central Africa), and I have very few days left before I leave. The machine is very important to our team and our recycling project, and if I leave without fixing it, I don’t think they will be able to recover it.

Do you have any idea what the problem might be?

Best regards, and thanks for your help,

Carlos

Is it possible, yes. If you disconnect hardware from a running machine, you can damage it.
Is it likely? No.
You more than likely had multiple things happen when your colleague moved the SKR board.

High resolution pictures of the front and back of your setup would be helpful, along with some basic troubleshooting information:

With the USB disconnected, and the machine powered on, what LEDs light up on the SKR?
Do you use an LCD? If so, what appears on the LCD as you power it up?

If you put the SD card in a reader and put that in another computer, you note it shows up as empty. Very possibly the SD card was corrupted, in which case it may be able to be reformatted.

If the SD card cannot be reformatted, then you’re getting indications that something may have been damaged- but we should troubleshoot further .

What type of machine is this SKR in?

Hi Jim, thank you for your help. Here’s my response.

When I connect the board to the power, the following LEDs light up:

Blue LED that recognizes the SD card.
Three orange LEDs for 3.3V, 5V, and 12V.
Red LEDs for E2 and Z1 motor drivers, but none for X, Y, E1 (they remain off despite having their cables connected).

On the LCD screen, the startup page displays the following:

V1 Marlin Mode
Marlin
515D 2.1.1
marlinfw.org

When I connect it via USB with my program, I can find the corresponding COM port and establish a connection with the SKR. However, when I send a command to move an axis, the program indicates: “Waiting for command.” The machine does not move, although it does set a 0,0,0 origin (something that doesn’t happen on the LCD).

This is an MPCNC with dual endstops.

I also copied and pasted the firmware.bin file to flash the board onto the SD card (it is the only file on the SD). I re-inserted the SD card, but this file has neither changed its name nor its extension after doing this.

Visually, the board looks fine; it doesn’t seem to have any damaged, burnt, or cracked components. There are no smells or liquids. The three fuses are in good condition. I have attached photos.

Thanks again for your help,

Carlos

Carlos:

On the LCD screen, the startup page displays the following:
V1 Marlin Mode
Marlin
515D 2.1.1
marlinfw.org
When I connect it via USB with my program, I can find the corresponding COM port and establish a connection with the SKR.

Good news, the board firmware is alive. No need to try and flash any firmware at the moment.

Send the board an M503 , an M122, and a M119. Send these in the as-is state first, then again after the note below. Report both sets of results.

Here’s a clue. You don’t have working drivers in the locations with no LED.

Power down the SKR, and remove everything except the incoming pair of power wires.
Power back up.
Repeat the M commands from above and also note the LED status indicators from the stepper drivers when you power back up.

Hi there!

I think we are in the good direction, now I have een able to move the CNC with my program, but there are still some motors that are not working. I send you the results of both tests (with and without the wires attached)

Right now, all 6 LEDS (X, Y, Z1, E0, E1, E2) are on.

Hi Jim,

You have already help mea lot, but I am really short of time and I don’t find the solution to my problem. Could you please give me some helpp with the code I sended you? Thank youso much for your help in advance.

Carlos

Somehow I didn’t see your reply, so hadn’t looked at this yet.

What I see consistently in your results is sumarized below

This means that for some reason UART communication between Marlin firmware and the UARTs in your TMC 2209s isnt working properly. That’s what we need to solve.

Hopefully the rest of the community can help with troubleshooting this. Later today I’ll try to go back over the photos you posted. Can you also post high-resolution photos of the tops and undersides of your TMC2209 drivers?
