12How to build
13============
14
15From OP-TEE build repository:
16
17 $ make PLATFORM=stm32mp1-157A_DK1 all
18or
19 $ make PLATFORM=stm32mp1-157C_DK2 all
20or
21 $ make PLATFORM=stm32mp1-157C_EV1 all

23How to write the microSD card
24=============================
25
26Once the build process is finished you will have an image called
27"sdcard.img" in directory ../out-br/images/ (relative to build
28repository root path).
29
30Copy the bootable "sdcard.img" onto an microSD card with "dd":
31
32  $ sudo dd if=../out-br/images/sdcard.img of=/dev/sdX \
33	    conv=fdatasync status=progress
34
35Boot the board
36==============
37
38 (1) Insert the microSD card in connector CN15
39
40 (2) Plug a micro-USB cable in connector CN11 and run your serial
41     communication program on /dev/ttyACM0.
42
43 (3) Plug a USB-C cable in CN6 to power-up the board.
44
45 (4) The system will start, with the console on UART. Both secure
46     and non-secure console consoles are on the same UART bus.
