Manta M8P V2.0 Bootloader

[taalabash]

Hello, can anyone please upload the V2 bootloader, I think my board has a dmaged bootloader/ mcu, I just got three days ago without having the chance to use it till now, I'm trying to flash the firmware using sd card but it's not working, I tried to run the command "lsusb" on CB1 but it didn't show any device related to STM, by running "ls /dev/serial/by id/" I am recieving "ls: cannot access '/dev/serial/by-id/': No such file or directory", so seems the board is stuck on this state now.

Also having this issue. It seems the problem is the /dev/serial/ directory doesn't exist.

Hello, same issue after following the EBB SB2240 guide. After flashing the board in DFU mode, the mcu doesn't respond in klipper because it can't find serial :/

I solved the problem by running: M8P V2.0 Board is BOOT0 + RESET --> DFU Mode change lsusb .... Bus 002 Device 003: ID 0483:df11 STMicroelectronics STM Device in DFU Mode .... sudo dfu-util -a 0 -D ~/klipper/out/klipper.bin --dfuse-address 0x08000000:force:mass-erase -d 0483:df11 <- run .... File downloaded successfully make flash FLASH_DEVICE=0483:df11 <- run .... ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0 Found canbus_uuid=d208fb6c3a9a, Application: Klipper Found canbus_uuid=d2fa09dcad7f, Application: CanBoot

Flashing https://github.com/bigtreetech/Manta-M8P/blob/master/V2.0/Firmware/M8P_V2_H723_bootloader.bin with the dfu then trying to use dfu-util for future updated seems not to work. Have to alway switch to dfu using the hardware buttons

If the device is already in bootloader mode it can be flashed with the following command: make flash FLASH_DEVICE=0483:df11 OR make flash FLASH_DEVICE=1209:beba

If attempting to flash via 3.3V serial, then use: make serialflash FLASH_DEVICE=0483:df11

For those if us that don't speak German (I think) , can you please explain what is wrong with the pdf?

[manotroll]

Encontrei a solução para o problema em um vídeo no YouTube, Vou colocá-lo aqui para que você possa ver Há um erro na explicação em PDF no manual sobre como fazê-lo https://www.youtube.com/watch?v=k8DmTrY2GgY

Para aqueles que não falam alemão ( acho que ), você pode explicar o que há de errado com o pdf?

basically you shouldn't use boot loader
