Booting from SD Card
Booting from the SD card is useful in several situations, e.g. if the board does not start anymore due to a damaged bootloader. To boot from SD card,
switch S1 position 1 has to be set to ON.
There are two ways to create a bootable SD card. You can either use:
A single, prebuilt SD card image
The four individual images (
-, kernel- and device tree image, and root filesystem)
u-boot
Single, Prebuilt SD Card Image
The first possibility is to use the SD card image built by
, a tool integrated in
. This image has the ending
and can be found under
Bitbake
Yocto
*.sdcard
buil
. It contains all BSP files in correctly preformatted
d/deploy/images/phyboard-pollux-imx8mp-1/phytec-qt5demo-image-phyboard-pollux-imx8mq-1.sdcard
partitions and can be copied to the SD card easily using the single
command
.
Linux
dd
