Hi:
I use i.MX6 Series SABRE, u-boot-2009.08,linux-3.0.35
I had modified mx6q_sabresd.h in uboot:
#define CONFIG_CMD_SATA
#undef CONFIG_FSL_ENV_IN_MMC
#define CONFIG_FSL_ENV_IN_SATA
after uboot boot,printf:

It's wrong use SATA in-uboot, but I had tested mount filesystem on SATA in Linux.
WhereI need modify in u-boot?
Best Regards,
Solved! Go to Solution.
please check GPR13 in linux:
linux source code(arch/arm/mach-mx6/board-mx6q_sabresd.c)
and make the same settings in UBoot:
board/freescale/mx6q_sabresd/mx6q_sabresd.c
Also in Uboot check CCM CG2 register CCM_CCGR5 so sata clock
will be enabled.
Hi William
I think below may help

May be useful to check GPR13 in Uboot and Linux.
Best regards
igor
I have sata cmd in u-boot,but sata init faied
MX6Q SABRESD U-Boot > sata init

The same SATA can mount in Linux.
please check GPR13 in linux:
linux source code(arch/arm/mach-mx6/board-mx6q_sabresd.c)
and make the same settings in UBoot:
board/freescale/mx6q_sabresd/mx6q_sabresd.c
Also in Uboot check CCM CG2 register CCM_CCGR5 so sata clock
will be enabled.
