|

|
+**********************
|
|
|
+
|
|
|
+This file documents the Buildroot support for the i.MX 93 FRDM
|
|
|
+(Freedom) board. For more information on this board, see [1].
|
|
|
+
|
|
|
+
|
|
|
+Build
|
|
|
+=====
|
|
|
+
|
|
|
+First, configure Buildroot for the i.MX 93 FRDM board:
|
|
|
+
|
|
|
+ make freescale_imx93frdm_defconfig
|
|
|
+
|
|
|
+Build all components:
|
|
|
+
|
|
|
+ make
|
|
|
+
|
|
|
+When this command completes, the generated image containing everything
|
|
|
+to boot from the SD card is located in "output/images/sdcard.img".
|
|
|
+
|
|
|
+
|
|
|
+Create a bootable SD card
|
|
|
+=========================
|
|
|
+
|
|
|
+To determine the device associated to the SD card have a look in the
|
|
|
+/proc/partitions file:
|
|
|
+
|
|
|
+ cat /proc/partitions
|
|
|
+
|
|
|
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
|
|
|
+directory, ready to be dumped on a SD card. Launch the following
|
|
|
+command as root:
|
|
|
+
|
|
|
+ dd if=output/images/sdcard.img of=/dev/<your-sd-device>
|
|
|
+
|
|
|
+*** WARNING! This will destroy all the card content. Use with care! ***
|
|
|
+
|
|
|
+For details about the medium image layout, see the definition in
|
|
|
+board/freescale/common/imx/genimage.cfg.template_imx9.
|
|
|
+
|
|
|
+
|
|
|
+Boot the i.MX 93 FRDM board
|
|
|
+===========================
|
|
|
+
|
|
|
+To boot your newly created system (refer to the i.MX 93 FRDM
|
|
|
+Documentation [2] for guidance):
|
|
|
+- insert the SD card in the SD slot (P13) of the board;
|
|
|
+- Configure the SW1 boot switches as follows:
|
|
|
+ SW1: 1100 SW1[1-4] ("USDHC2 4-bit SD3.0" Boot Mode)
|
|
|
+- connect a USB Type-C cable into the P16 Debug USB Port and connect
|
|
|
+ using a terminal emulator at 115200 bps, 8n1;
|
|
|
+- power on the board by connecting a USB Type-C cable into the P1
|
|
|
+ Power USB Port.
|
|
|
+
|
|
|
+Note 1: the board boot switches default configuration is:
|
|
|
+SW1: 0100 SW1[1-4] ("USDHC1 8-bit eMMC 5.1" Boot Mode)
|
|
|
+and the board is also pre-flashed with a reference Linux demo
|
|
|
+image. It is important to change the boot config switches to make
|
|
|
+sure the system will boot on the SD Card.
|
|
|
+
|
|
|
+Note 2: the debug USB connector presents 2 UARTs (for example
|
|
|
+/dev/ttyACM[0-1]), the Cortex-A55 UART should be the 1st one (in the
|
|
|
+previous example, /dev/ttyACM0). Refer to the documentation [2] for
|
|
|
+more details.
|
|
|
+
|
|
|
+Enjoy!
