|
|
|

an updated bootloader can also be programmed via DFU. This requires three
|
|
steps:
|
|

|
Normal BMP has to be replaced by the upgrade programm:
|
|
dfu-util -s 0x08002000:leave -D dfu_upgrade.bin
|
|
Wait until Dual color led flashes red, indicating DFU is active for the
|
|
bootloader.
|
|
|
|
2. Flash new bootloader
|
|
dfu-util -s 0x08000000 -D blackmagic_dfu.bin
|
|
Wait until Dual color led flashes green, indicating bootloader is active.
|
|
|
|
If not, unplug USB, keep black reset button pressed, replug USB.
|
|
Wait until Dual color led flashes green.
|
|
|
|
3. Flash BMP
|
|
dfu-util -s 0x08002000:leave:force -D blackmagic.bin
