Flashing failed - Cannot enter bootloader, check your `BOOT0/Reset` pins settings and try again

Hardware Setup Ender 3 / Creatlity 4.2.2

Describe the problem I tried this guide to flash the firmware, But the flashing process is failing with error

Flashing failed 
Cannot enter bootloader, check your BOOT0/Reset pins settings and try again

How can I update firmware on Creality 4.2.2 board with this plugin?

Not sure why you picked that method - Creality boards use avrdude. https://github.com/OctoPrint/OctoPrint-FirmwareUpdater/blob/master/doc/avrdude.md

Thanks for your reply!

I'm new to 3d printing and firmware programming, I saw STM32F103RE_creality when building Marlin. So I thought I should use STM32Flash. Let me try avrdude.

@benlye, Avrdude also failed 😢 it shows an error message like this

Flashing failed

avrdude done. Thank you.'

Oops, I take it back, it's not avrdude for the 4.2.2, it's either the lpc176x or marlinBFT method.

https://github.com/OctoPrint/OctoPrint-FirmwareUpdater/blob/master/doc/lpc176x.md https://github.com/OctoPrint/OctoPrint-FirmwareUpdater/blob/master/doc/marlinbft.md

Both are a bit of a pain to set up, but work equally well once you get there. The dependencies for MarlinBFT can be a particluar pain for Python 3.9 (see #349).

[jkmathew]

Hmm... I think both these won't work in my case, The reason I tried firmware updater instead of flashing with conventional sdcard reboot is because my printer going into a boot loop when I boot the printer with sd card inserted.

I tried lpc176x.md, but I could not get the sdcard mounted on the pi(I think). When I test Path to firmware folder It gives the error The path is not writeable

And for MarlinBFT, I have to flash Marlin once, I am not able to do this because of the issue I mentioned earlier.

[benlye]

Ah, if you can't use the on-board SD card slot then I'm afraid the plugin can't help you.

Depending on your level of determination you might be able to flash it with an ST-Link device, using the SWDIO and SWCLK header pins (next to the LCD connector).

You might be able to get better help in a Creality Ender group or forum.

[jkmathew]

Thank you for the reply. Closing this issue since we cannot go forward more, unfortunately.

As a last note, I am formating the sd card from a MacBook, I suspect this case the problem of boot loop (not sure here as well). I will try to format it from the pi and flash.

You might like to try this program to help clean up the SD card before you remove it from your Mac: https://www.javawa.nl/cleaneject_en.html
