Cannot flash Odrive3.5 with StLINK V2-1

Neurotronic67 · October 28, 2018, 9:27am

Hi,
I have my Odrive 3.5 48V since July, and it didn’t work since…
When I plug my board in my computer, odrivetool on my Ubuntu 16.04 doesn’t recognize the card.
I first thought it was the USB race condition issue, and I wait to the bug be fix…
but since the last update, it didn’t work…

So I wonder that the card don’t have any firmware install inside (and one post give me the confirmation).
First, I tried to compile the DFU using the usb (and flip the dfu force switch) but it didn’t work
So I have a ST-LINK V2-1 coming from a old Nucleo board, I install OCD and all the dependencies, and give it a shot connecting the SWC/GND/SWD programming port on my st-link V2-1 and changing the config like this :

openocd -f interface/stlink-v2-1.cfg -f target/stm32f4x.cfg -c init -c "reset halt" -c "flash write_image erase ODriveFirmware_v3.5-48V.elf" -c "reset run" -c exit

and the console give me this :

Then I thought, it was done, and but back the switch to RUN MODE.
Run the power
connect to my computer and run odrivetool
AND IT STILL DOESN’T WORK.

If you have any idea…
thanks in advance for your answer !

Hi Neuro- I had troubles with openocd for days, i had the “exact” output as you had.

Ended up using WIN10 and followed this path “You can use the DfuSe app from ST.”

Download the tool here

This has 1 of my ODrive boards working.

Hope this helps

Regards Jerry

I will give it a shot !
but how can windows can recognize the board without the firmware ?

Neurotronic67 · October 28, 2018, 8:26pm

I use zazig to find the odrive, because when I connect the odrive my windows computer don’t detect the board.
(like : ODrive 3.x Native Interface (Interface 2))

is it the interface 2 ?

Neil_FV · October 29, 2018, 8:16am

There’s no voltage at the cpu. Can you measure the voltage on the board with a DVM?

Neurotronic67 · October 29, 2018, 8:53am

Maybe I have to flash with the target voltage coming from the STLINK ?

I will go with the alternative of using DfUSe on windows.
But I don’t know why windows don’t show up the board.
I use Zazig, to change the USB driver but now I don’t know which is the correct interface to modify…

please help…

The STLINK won’t power the cpu, you’d need to apply your external power source at the screw terminals.

From “Getting Started” in the Docs area:
Use the Zadig utility to set ODrive driver to libusb-win32.

Check ‘List All Devices’ from the options menu, and select ‘ODrive 3.x Native Interface (Interface 2)’. With that selected in the device list choose ‘libusb-win32’ from the target driver list and then press the large ‘install driver’ button.

Okey,
My board is powered with an 32V battery, and I check the terminal I’ve got 3.3V and 5V.
But when I use the zazig utility, When I check the list, there is no ODrive 3.x Native Interface (Interface 2)…
I don’t know what to do…

I DID IT
I upgrade the firmware on my ST-LINK V2-1
and use ST-LINK utility to check some memory element, then I flash the board using the .hex file
and it work !

I think using the ST-link utility is a good option to diagnostic and flash the CPU !

thanks for your help !

Hi. I have the same problem as PC does not recognise Odrive in Run mode after updating firmware with ST Link V2. Could you show me how you upgraded the firmware on your ST-LINK V2-1?
