#147 Error Probing interface "serial_posix"

[Brandon Cramer]

Hello,

I'm trying to flash klipper onto an Octopus Pro. I went through restoring the boot loader instructions this morning but I'm still having issues flashing Klipper firmware ontoo the Octopus Pro.

Here are the logs from me trying to flash the firmware.

Any help would be great. Not sure if I'm dealing with a corrupt board or not.

Thanks,
Brandon

I think you are mixing up stm32flash and dfu-util. 0483:df11 is the USB ID of a plugged-in device in DFU mode, whereas stm32flash works with the serial line bootloader. If the device shows up in DFU mode on USB, the serial bootloader is not activated.

[Brandon Cramer]

So it sounds like the board isn't going into the correct mode. Would it show up here or not show in DFU mode if it was ready to flash?

When the DFU device appears, it should be ready to flash over USB. Please report at https://sourceforge.net/p/dfu-util/tickets/new/ with the information asked there. In addition you can attach the output from sudo lsusb -d 0483: -v

There are several issues here: You are using dfu-util 0.9, whereas the latest (and only supported) release is 0.11. The Makefile you are using is adding the -R flag, this is likely a mistake. Where is this Makefile coming from?
