eMMC:

|

|
ROM supports booting from eMMC from boot0 partition offset 0x0
|
||||||
|
|
||||||
|
Flashing images to eMMC:
|
||||||
|
|
||||||
|
The following commands can be used to download tiboot3.bin, tispl.bin,
|
||||||
|
u-boot.img, and sysfw.itb from an SD card and write them to the eMMC boot0
|
||||||
|
partition at respective addresses.
|
||||||
|
|
||||||
|
=> mmc dev 0 1
|
||||||
|
=> fatload mmc 1 ${loadaddr} tiboot3.bin
|
||||||
|
=> mmc write ${loadaddr} 0x0 0x400
|
||||||
|
=> fatload mmc 1 ${loadaddr} tispl.bin
|
||||||
|
=> mmc write ${loadaddr} 0x400 0x1000
|
||||||
|
=> fatload mmc 1 ${loadaddr} u-boot.img
|
||||||
|
=> mmc write ${loadaddr} 0x1400 0x2000
|
||||||
|
=> fatload mmc 1 ${loadaddr} sysfw.itb
|
||||||
|
=> mmc write ${loadaddr} 0x3600 0x800
|
||||||
|
|
||||||
|
To give the ROM access to the boot partition, the following commands must be
|
||||||
|
used for the first time:
|
||||||
|
=> mmc partconf 0 1 1 1
|
||||||
|
=> mmc bootbus 0 1 0 0
|
||||||
|
|
||||||
|
To create a software partition for the rootfs, the following command can be
|
||||||
|
used:
|
||||||
|
=> gpt write mmc 0 ${partitions}
|
||||||
|
|

Kernel image and DT are expected to be present in the /boot folder of rootfs.
|

To boot kernel from eMMC, use the following commands:
|
||||||
|
=> setenv mmcdev 0
|
||||||
|
=> setenv bootpart 0
|

=> boot

help

|
On some platform we have sufficient memory available early on to
|
||||||
|
allow setting up and using a basic BSS prior to entering
|
||||||
|
board_init_f. Activating this option will also de-activate the
|
||||||
|
clearing of BSS during the SPL relocation process, thus allowing
|
||||||
|
to carry state from board_init_f to board_init_r by way of BSS.
