booting from SATA works very well on my iMX6 based board, however if I do
#define CONFIG_ENV_IS_IN_FAT
#if defined(CONFIG_ENV_IS_IN_FAT) #define CONFIG_FAT_WRITE #define FAT_ENV_INTERFACE "sata" #define FAT_ENV_DEVICE_AND_PART "0:1" #define FAT_ENV_FILE "u-boot.env" #endif
nothing is loaded as the SATA has not been initialised.
Looking at board_r.c I can see lots of inits, for mmc, nand and other stuff, but not sata.
Following the format I have added a function
#ifdef CONFIG_CMD_SATA static int initr_sata(void) { puts("SATA: "); sata_initialize(); return 0; } #endif
and inside init_fnc_t init_sequence_r[] = { after
#ifdef CONFIG_GENERIC_MMC initr_mmc, #endif
I have added
#ifdef CONFIG_CMD_SATA initr_sata, #endif
So this compiled and booted and to my surprise worked. Is this the best way to achieve this. I can see potential problems if sata_inialize() depends on other sub-systems being initialized first. I am perhaps lucky that it works for me.
