Programming and Debugging
14+
*************************
15+
16+
Prepare a TF card and follow the instructions in the `official SDK`_ to build
17+
and flash the image.
18+
19+
After that, you will get a ``fip.bin`` file at the root of the TF card, where
20+
the RTOS image is packed.
21+
22+
The following steps demonstrate how to build the blinky sample and update the
23+
``fip.bin`` file on the TF card.
24+
25+
.. zephyr-app-commands::
26+
:zephyr-app: samples/basic/blinky
27+
:board: milkv_duos/sg2000/c906_1
28+
:goals: build flash
29+
:flash-args: --fiptool /path/to/duo-buildroot-sdk/fsbl/plat/cv181x/fiptool.py --fip-bin /path/to/tfcard/fip.bin
30+
31+
Eject the TF card and insert it into the board. Power on the board and you will
32+
see the LED blinking.
33+
34+
.. note::

36+
Notes for the official buildroot SDK
37+
38+
1. The Linux running on the big core uses UART0 (A16/A17) for the console,
39+
while to avoid conflict, the Zephyr application (in the default board
40+
configuration) uses UART2 (A19/A18).
41+
2. Pin multiplexing can be handled either by U-Boot or Zephyr. To utilize
42+
Zephyr's pin multiplexing, enable :kconfig:option:`CONFIG_PINCTRL` and
43+
recompile U-Boot without the `PINMUX configs`_. Note that U-Boot boots
44+
several seconds after Zephyr.
