| + | ====== About BOOT.INI ====== | ||
| + | In order to support easy boot loader setup, ODROID-C1 also support **boot.ini** as well as previous ODROID boards. So you can easily list up the commands what you want to executed in U-boot rather than the default. Here is the example to boot Ubuntu. | ||
| + | <file> | ||
| + | ODROIDC-UBOOT-CONFIG | ||
| + | setenv hdmimode "720p" | ||
| + | |||
| + | # HDMI BPP Mode | ||
| + | setenv m_bpp "32" | ||
| + | |||
| + | setenv bootargs "console=ttyS0,115200n8 root=UUID=e139ce78-9841-40fe-8823-96a304a09859 rootwait ro no_console_suspend vdaccfg=0xa000 logo=osd1,loaded,0x7900000,720p,full dmfc=3 cvbsmode=576cvbs hdmimode=${hdmimode} m_bpp=${m_bpp} mac=${ethaddr}" | ||
| + | setenv bootcmd "fatload mmc 0:1 0x21000000 uImage; fatload mmc 0:1 0x22000000 uInitrd; fatload mmc 0:1 0x21800000 meson8b_odroidc.dtb; bootm 0x21000000 0x22000000 0x21800000" | ||
| + | run bootcmd | ||
| + | </file> | ||
| + | ===== Board Identifier ===== | ||
| + | This is the keyword to identify the correct **BOOT.INI** as per board. For **ODROID-C1**, any **BOOT.INI** must contain **ODROIDC-UBOOT-CONFIG** and other commands must be below this. | ||
| + | ===== U-boot commands ===== | ||
| + | You can describe multiple commands of U-boot from the next line of **ODROIDC-UBOOT-CONFIG**. The commands are only restricted within the commands enabled by the running U-boot. | ||
