This change has also a practical reason. When flashing and testing the
hardware this change makes it easier to make sure all the LEDs work. Now
when the DFU bootloader is idle it is scanning the LEDs making it easy
to see if one of them has an issue.
In addition to that, the bootloader now indicates when there is data
being flashed using the DFU interface. In cases when one has more than
one device connected and accidently starts flashing a wrong device this
is very useful feature to have.
Hello,
appended 3 patches
- adds a dfu-bootloader appliaction
- uses absolute delays when waiting for pull-up delays on the STLINK
(hopefully fixes issue #30)
Updating the dfu-bootloader by additional application is helpfull for the
STLINK, as for flashing the bootloader by SWDb otherwise jumpers need to be
soldered or external SWD is not possible.
Use like:
- dfu-util -s 0x08002000:leave -D dfu_upgrade.bin
- dfu-util -s 0x08000000:leave -D blackmagic_dfu.bin
- Push reset buttom and reconnect to enter new dfu bootloader
- dfu-util -s 0x08002000:leave -D blackmagic.bin
