Klipper and new bootloader #20

Open asha77 opened 3 years ago

asha77 commented 3 years ago

Hi, i've got error with new bootloader and klipper firmware with S6 board. Firmware uploaded using STM32cube and DFU. Sequence:

  1. Enter DFU Mode
  2. Upload Latest bootloader
  3. Restart Board
  4. Upload latest klipper compiled firmware. Start address set to 0x08010000
  5. Flashing successfull
  6. Attach S6 to RPI
  7. Starting Klipper, Firmware working OK, I can print
  8. When I reboot board with BOOT jumper set to DFU - it goes to DFU mode (expected)
  9. Whet I remove DFU Jumper and reboot board - USB cannot detect board anymore. It becomes brick.

I can repeat steps 1-7 to make it work again, but it is not expected scenario.

Please, advice what to do with that, thank you in advance.

Can i ask why you want to set to DFU at step 8?

asha77 commented 3 years ago

Just to check how it starting with and without jumper. Important note: on step 7 it starts OK from STM32cube, not from hard reset (power cycle reset button). Steps 8, 9 - made with hard reset.

You can use our prebuild to test the bootloader: https://github.com/FYSETC/FYSETC-S6/tree/main/firmware/Pre-builds, it is Marlin build, you can send "M105" command to test if board works ok. I double check my side, it works. And i recommend a hard reset after you flash firmware.

Hi,

I am experiencing the same scenario exactly. Did you ever resolve this?

asha77 commented 2 years ago

Hi, after some manipulations i get board back to work. Unfortunately i not tried to reproduce this issue, i can't privide any clear instruction to fix it.

teeedubb commented 2 years ago

Compiling klipper for no bootloader solved the issue for me, it now works after a reboot.

asha77 commented 2 years ago

I got this issue once again. yes, klipper with no bootloader option did it:

After restart S6 octoprint can communicate with klipper.

There is some info in the fysetc section on the klipper discord about flashing these boards.
