## Flashing
There are several options for flashing kirdy. DFU requires only a USB-C connector, whereas OpenOCD needs a JTAG/SWD adapter.
There are several options for flashing kirdy. DFU requires only a USB-C cable or RJ45 cable, whereas OpenOCD needs a JTAG/SWD adapter.
### dfu-util on Linux
* Install the DFU USB tool (dfu-util).
* Convert firmware from ELF to BIN: `arm-none-eabi-objcopy -O binary kirdy kirdy.bin` (you can skip this step if using the BIN from Hydra)
* Connect to the USB Type C connector to kirdy above the RJ45.
* Add jumper to kirdy v2.0 across 2-pin jumper adjacent to JTAG connector.
* Cycle board power to put it in DFU update mode
* Put STM32 into DFU Mode. You can either
* Connect to the USB Type C cable to kirdy next to the RJ45 Jack. After that, add BOOT0 jumper to kirdy near programming headers and then cycle board power to put it in DFU mode. OR
* Plug in RJ45 cable, which connect to a network that is accessible by your computer and send the corresponding dfu json command via TCP Socket to kirdy. Please see the python test script for the command.
* Push firmware to flash: `dfu-util -a 0 -s 0x08000000:leave -D kirdy.bin`
* Remove jumper
* Cycle power to leave DFU update mode
* If you plugged in the BOOT0 jumper, you will need to
1. Remove BOOT0 jumper
2. Cycle power to leave DFU update mode
* If you plugged in the RJ45 cable, the MCU would start its application code automatically. No power cycle is needed.
