How to use U-Boot on Freescale MX6SXSCM boards
----------------------------------------------
- Build U-Boot for MX6SXSCM EVB board*:
$ make mx6sxscm_1gb_evb_defconfig
$ make
This will generate the u-boot image u-boot.imx.
- Flash the u-boot image into the micro SD card:
sudo dd if=u-boot.imx of=/dev/sdX bs=1k seek=1; sync
*Other defconfigs availabe are:
mx6sxscm_1gb_evb_defconfig
mx6sxscm_1gb_evb_m4fastup_defconfig
mx6sxscm_1gb_evb_qspi2_defconfig
- Jumper settings for fix mode images to boot from the top SD3:
SW2: OFF OFF OFF OFF OFF OFF OFF OFF
SW3: OFF OFF ON ON OFF OFF OFF OFF
SW4: OFF ON OFF OFF OFF OFF ON OFF
Additional configurations
==========================
For custom configurations like 512MB or ePOP, the CONFIG_SYS_EXTRA_OPTIONS option on the defconfig
file can be modified according to the customization needed.
Here are some examples for some combinations among the different supported options:
512mb evb
---------
CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx6sxscm/imximage_lpddr2.cfg,MX6SX,512MB_LPDDR2"
epop evb:
---------
CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx6sxscm/imximage_lpddr2.cfg,MX6SX,512MB_LPDDR2,MX6SXSCM_EMMC"
epop evb qspi2-boot:
--------------------
CONFIG_SYS_EXTRA_OPTIONS="IMX_CONFIG=board/freescale/mx6sxscm/imximage_lpddr2.cfg,MX6SX,512MB_LPDDR2,MX6SXSCM_EMMC,SYS_BOOT_QSPI"
