ποΈ Introduction
Version 1.0
ποΈ Boot the Mars CM
Mars CM has two versions based on storage, one is Mars CM with eMMC storage, and the other is Mars CM Lite without eMMC storage. The Lite version can only be accessed through SD card on the base-board. If the base-board you are using does not have a SD card interface, you cannot use the Lite version. In addition, the eMMC version shares the hardware interface with the SD card, so they cannot be used at the same time. In other words, when using the eMMC version of Mars CM, you cannot insert a storage card into the SD card slot on the base-board.
ποΈ Setting Up
Use Serial Console
ποΈ Extend Partition
The default capacity of the official Debian image root file system is about 4GB. When installing software or other data increases, there will be insufficient space. We can expand the file system to the full capacity of the SD card or eMMC.
ποΈ Bootloader Update
Whether Mars CM starts the system through the SD card or the eMMC module, it must be started through the Bootloader boot program. This boot program is stored in an SPI Flash on the board and contains two parts: SPL and U-Boot.
