- The microSD card should be larger than 8GByte, and prepared by Lophilo OS card partition tool.
- The prepared card has two partitions: boot (1GByte, MSDOS FAT), linux (from 7GByte to card size limit, Linux EXT4).
- Insert the SDcard to PC's card reader, and mount the "boot" partition (on Windows, only "boot" partition is recognized and automatically list in "My Computer").
- Copy the generated excutable binary "boot.bin" (File name is sensitive) to the "boot" partition.
- Also copy "boot.ini", "zImage" and "grid.rbf" (File names are all sensitive) to the "boot" partition.
- DD the OS filesystem to the "linux" partition.
- Put microSD card to the card holder on XEM, and we are done.
noinitrd mem=128M console=ttyS0,115200 root=/dev/mmcblk0p2 rootfstype=ext4 rw rootwait
- Only for booting Linux on Lophilo's hardware platform.
- Running directly from micro SDcard, no need to program any special flash on hardware.
- Initially developed with Keil MDK, then the project was converted for developing with gcc.
- Final excutable binary size should be limited under 55kByte to fit into SAM9M10's IRAM.
- Some code is based on ATMEL's at91lib.
