Wrong MCU Firmware configuration

[jayxcfgj]

In the actually documentation V1.0 are the wrong MCU Firmware configuration. There are declared a bootloader offset with 8 KiB. This creates issues and after compile tthis you can't get the serial of the board.

Please correct the doku to the correct working setting "no bootloader".

Do you have a solution to reflash the firmware because I made the mistake and now I'm trying to go through the sd card but the firmware.bin file is not taken into account when the card is completely rebooted.

@palouf34 you can try to reflash the firmware through the DFU like this: https://www-drklipper-de.translate.goog/doku.php?id=klipper_faq:flash_guide:stm32h743:btt_manta_m8n_usb&_x_tr_sl=auto&_x_tr_tl=de&_x_tr_hl=de&_x_tr_pto=wapp

For those who lost the original bootloader, here's a copy of mine. You can upload it to CB1 using WinSCP, MobaXterm or something similar (e.g. to the ~/klipper/out directory). After that:

1. Put the board into DFU mode.
2. Check with the lsusb command that the board has successfully entered DFU mode.
3. Warning, this will remove the current firmware!! Run the command sudo dfu-util -a 0 -d 0483:df11 --dfuse-address 0x08000000:force:mass-erase -D ~/klipper/out/Manta_M5P_bootloader.bin.
