How to flash bootloader? #115

Open chrstrvs opened 4 years ago

chrstrvs commented 4 years ago

Hi!

I accidentally shorted a IO pin to 5v and fried the processor. The rest of the board appears to be working, so I'm thinking of swapping the processor for a new one, but I need to flash the bootloader to it. I understand that I need a ST Link programmer, but how do I hook it up to the SKR Pro board?

Thanks in advance!

Regards, Christian

@chrstrvs Check out this #72

Thanks, that's exactly what I needed!

For clarification : 1) Jumper BOOT0 Pin to 3.3V 2) Get and FTDI Adapter, 3) Download https://www.st.com/en/development-tools/flasher-stm32.html 4) Make sure logic voltage switch on FTDI Adapter is 3.3v 5) Connect to SKR Pro 1.1 as follows : Connect FTDI 3.3v and ground to SKR 3.3v (near UART CONNECTOR) and ground pins 6) Connect FTDI TX to TFT Connector RX1 and FTDI RX to TFT Connector TX1 (For me the UART TX and RX Pins didnt work) 7) Open Demonstrator GUI, select the correct com port click next. If error appears, check wires 8) If OK, message will confirm connection Click Next again and and Next Again 9) In the next screen click the ... near the downoad to device section and select the .BIN file to upload. 10) Click next and wait. 11) When done, dont forget to remove the BOOT0 jumper.

FYI Marlin firmware does not contain the bootloader, you'll need a copy of firmware which includes the bootloader.

I will probably be using a ST-LINK adapter. Am I right in assuming that I will replace steps 4 to 10 with connecting the ST-LINK adapter to 3.3v, ground and SWD pin and use ST-LINK sw to burn the bootloader?

c3D-Dan commented 4 years ago

Im sorry I don't have an ST-Link.

npmomchev commented 4 years ago

Is it possible for someone to share only bootloader.bin which does not include firmware in self

Thank You

codmpm commented 4 years ago

As I've obviosly bricked my SKR 1.4 Turbo, can someone point me to the bootloader.bin for it? It's an LPC1769 thus the SKR 1.1 bootloader won't work.

Also its difficult for me to find BOOT0 on the 1.4 board.

When I understood it correctly it should be R28 according to the schematics: https://github.com/bigtreetech/BIGTREETECH-SKR-V1.3/raw/master/BTT%20SKR%20V1.4/Hardware/BTT%20SKR%20V1.4-SCH.pdf So I have to desolder R28 and pull it's pin low to be able to flash the bootloader?

AnHardt commented 4 years ago

Dear @codmpm . Here we are at the BIGTREETECH-SKR-PRO-V1.1 issue tracker. It's using a STM32F407 processor. LPC-processors are completely out of scope here.

codmpm commented 4 years ago

Oh, I'm sorry. I did not see this when writing my comment. Thank you!

AnHardt commented 4 years ago

I did see this when writing my comment.

And why did you do it anyway?

codmpm commented 4 years ago

Sorry... did not see it.

  1. Make sure logic voltage switch on FTDI Adapter is 3.3v

Is this realy 3.3V? image

c3D-Dan commented 4 years ago

Yes. Just because there is a Voltage regulator providing 5v to a variety of pins does not mean the logic voltage runs at 5v. Look at the stm32f4v7 datasheet. Pump 5v into a logic pin and kill each pin one by one. If you kill the TX RX pins with 5v logic, you’ll need to replace the processor.

@c3D-Dan, Thank you so much for these instructions and .bin file. I managed to bring an skr pro back from the dead, and finding these instructions were key for me. I couldn't get my FTDI dongle to work in windows (I'm not a windows expert), but I did manage to do it in Linux. Here's what I did:

  1. Set the Boot0 to 3.3V jumper (it is labeled on the underside)
  2. Connect the FTDI Rx to Tx3 (LCD), FTDI Tx to Rx3 (LCD), FTDI GND to GND (I used the LCD pin).
  3. Connect the FTDI 3.3V to the 3.3V port near the LCD connector.
  4. Installed stm32flash (I'm using ubuntu 18.04): 
    sudo apt install stm32flash
  5. Run the stm32flash with the .bin file you provided, and the port that the FTDI uses: 
    stm32flash -w BTTSKRPro1.bin /dev/ttyUSB0
  6. It took about a minute, and it confirmed it flashed to 100%
  7. Remove the FTDI from the computer, and then undo steps 1 and 2. Don't forget the jumper.

@c3D-Dan could you please re-upload the bootloader image and/or update the link?

Hello all, my Pro 1.1 dont read the Firmware from Sd anymore. So i look at the Steps to install the new Firmware and bootloader via FTDI Adapter

I connect Vcc to 3.3V Gnd to Gnd. TX to TFT Connector RX1 and FTDI RX to TFT Connector TX1 dont work so i go to RX and TX on Urat same problem.

No response from the target, the Boot loader can not be startet.

The red light on Skr 1.1 Pro is shown when i plug the FTDI in.

schnello commented 2 years ago

@ChrisS1986 I would do it as descriped it here: https://github.com/bigtreetech/BIGTREETECH-SKR-PRO-V1.1/issues/115#issuecomment-653814967

ChrisS1986 commented 2 years ago

I Do it as descriptet only on Windows. But it dont work, No response from the target, the Boot loader can not be startet.

Should i remove the wiring and driver for this?

So i try it tomorrow with ST Link, i ordert a BTT Octopus to replace the Skr 1.1 Pro.

I just got my Octopus Pro board in and I own several Octopus V1.0/V1.1 boards too. All I do to back up the SD Card bootloder is (on a WINDOWS OS machine): I use the Original (not a clone) ST-LINK-V2 device and hook it to the SWD connector on the Octopus V1.0/V1.1 board. Then I bring up https://www.st.com/en/development-tools/flasher-stm32.html Software and hit connect to TARGET. This always works but if you use a clone ST-LINK-V2. It may not work.

IMHO, you need to spend the money and purchase an ORIGINAL ST-LINK-V2 if you own any Bigtreetech boards especially if you only have WINDOWS OS. You can find and ORIGINAL ST-LINK_V2 at https://www.amazon.com/ST-LINK-V2-circuit-debugger-programmer/dp/B00SDTEM1I

The ORIGINAL ST-LINK-V2 might cost $50 but it is like any other tool you buy. You have to have the right tool to get the job done. I have spent $70 (7 clone ST-LINK_V2 @ $10.00 each) on the clones thinking they died on me. I wish I would had just laid down the $50.00 for the ORIGINAL at the very beginning!

I later found out the following: The clones will NOT connect to some Bigtreetech boards if you are using WINDOWS OS (If you are using LINUX that is a different story)! The ORIGINAL ST-LINK-V2 under WINDOWS OS will ALWAYS connect to the board.

Thank you again.

This method still worked as of 1/17/2022. I was re-flashing using Ubuntu 20.04, it took several unsuccessful attempts to get the board to flash. I had to hold the re-set button for approximately 30 seconds, wait a few seconds, then attempt to flash the board. It took ~5 minutes to flash.

Good as new. Thanks a bunch!!

I've been trying to get this to work, but just can't get stm32flash or Demonstrator to talk to the board. I'm thinking my board is truly dead... if I don't jumper BOOT0, the CPU gets very hot, also no memory card LED, and all the stepper LEDs are dimly lit. When jumpering either BOOT0 or BOOT1, the board does show up as a TTY device under Linux, but that's it.

I've tried it with a USB-TTL adapter and Raspberry Pi GPIO.

Any ideas or just give up and bin it? :)

qweritos commented 2 weeks ago

@pullasuti, with a high probability you burned the stm chip, and dimmed LEDs is also a clue. Check 1117 LDO chip, it also gets insanely hot. However, I burned stm many times, but after reflowing&reflashing it always gets back in operation :)
