# kflash --help
usage: kflash [-h] [-p PORT] [-f FLASH] [-b BAUDRATE] [-l BOOTLOADER]
[-k KEY] [-v] [-t] [-n] [-s] [-B BOARD] [-S SLOW]
firmware
positional arguments:
firmware firmware bin path
optional arguments:
-h, --help show this help message and exit
-p PORT, --port PORT COM Port
-f FLASH, --flash FLASH
SPI Flash type, 0 for SPI3, 1 for SPI0
-b BAUDRATE, --baudrate BAUDRATE
UART baudrate for uploading firmware
-l BOOTLOADER, --bootloader BOOTLOADER
bootloader bin path
-k KEY, --key KEY AES key in hex, if you need encrypt your firmware.
-v, --verbose increase output verbosity
-t, --terminal Start a terminal after finish (Python miniterm)
-n, --noansi Do not use ANSI colors, recommended in Windows CMD
-s, --sram Download firmware to SRAM and boot
-B BOARD, --Board BOARD
Select dev board, e.g. kd233, dan, bit, goD, goE or
trainer
-S SLOW, --Slow SLOW Slow download mode
Maixgo with openec firmware, BOARD must choose -B goE
, and should choose
sencond com port.
With cmsis-dap firmware(before 2019.02.21), BOARD must use -B goD
.
You can update new cmsis-dap firmware, it is same as openec.
For K210 Trainer V0.01b, BOARD must choose -B trainer
.
For KD233, BOARD must choose -B kd233
, and the jumper for kd233 automatic
download circuit must be set.

python>=3 or python=2.7
pyserial>=3.4
pyelftools>=0.25
Python3 is recommended.
If your python version below python3.4, you need:
python get-pip.py
python -m pip install pyserial
python -m pip install pyelftools
# When you python version below python3.4
python -m pip install enum34
