Octopus V1.1

Hi

I have problem flashing software on my Octopus V1.1  board.
I am building Voron printer at the moment.
Following both voron and big tree tech - github instructions I tried to flash using SD card. No luck with neither compiler on raspberry pi nor precompiled software - the blue light turns on but thats all,.. the software does not get flashed to the board nor is it any more responsive ...
Tried flashing over usb with raspberry pi but no device is detected on any of the ports.
The board is not even recognised in STM32CubeProgrammer.
At this point im out of ideas what to do, any help would be greatly appricieted.

Hi ,
Thanks for your information.

Please check 

First format the SD card and choose FAT32 as the file system. Then put two identical firmwares in the SD card. One named "firmware" and one named "firmware.bin".
Then update the firmware again. Check to see if any of the files on the SD card can be capitalized. Because some win10 systems hide the .bin suffix by default.

I have a freshly assembled Voron 2.4 with an octopus main board and 2209 stepper drivers. I can't seem to get past this error.

 

Unable to read tmc uart 'stepper_z' register IFCNT
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown

 

These are my firmware settings, any help would be appreciated 

 

# This file contains common pin mappings for the BigTreeTech Octopus V1.
# To use this config, the firmware should be compiled for the STM32F446 with a "32KiB bootloader"
# Enable "extra low-level configuration options" and select the "12MHz crystal" as clock reference

# after running "make", copy the generated "klipper/out/klipper.bin" file to a
# file named "firmware.bin" on an SD card and then restart the OctoPus with that SD card.

# See docs/Config_Reference.md for a description of parameters.

This problem is generally caused by the incorrect setting of the jumper cap of the driver port. Please provide a picture of the Z-axis jumper cap.
