This example implements a USB Device Firmware Upgrade (DFU) bootloader
|
||||
to demonstrate the use of the USB device stack.
|
||||
|
||||
Building
|
||||
--------
|
||||
|
||||
$ make
|
||||
|
||||
Running 'make' on the top-level libopenstm32 directory will automatically
|
||||
also build this example. Or you can build the library "manually" and
|
||||
then run 'make' in this directory.
|
||||
|
||||
You may want to override the toolchain (e.g., arm-elf or arm-none-eabi):
|
||||
|
||||
$ PREFIX=arm-none-eabi make
|
||||
|
||||
For a more verbose build you can use
|
||||
|
||||
$ make V=1
|
||||
|
||||
|
||||
Flashing
|
||||
--------
|
||||
|
||||
You can flash the generated code using OpenOCD:
|
||||
|
||||
$ make flash
|
||||
|
||||
Or you can do the same manually via:
|
||||
|
||||
$ openocd -f interface/jtagkey-tiny.cfg -f target/stm32.cfg
|
||||
$ telnet localhost 4444
|
||||
> reset halt
|
||||
> flash write_image erase systick.hex
|
||||
> reset
|
||||
|
||||
Replace the "jtagkey-tiny.cfg" with whatever JTAG device you are using, and/or
|
||||
replace "stm.cfg" with your respective config file.
