Hello,
I have a board with an SD card and an MMC on board. The SD card work good, but with MMC I have some problem. U-Boot list the MMC but can't do anything on it:
I2C: ready
DRAM: 512 MB
MMC: FSL_ESDHC: 0,FSL_ESDHC: 1
In: serial
Out: serial
Err: serial
i2c: I2C3 SDA is low, start i2c recovery...
I2C3 Recovery success
Serial reinitilized!
Net: No ethernet found.
Hit any key to stop autoboot: 0
...
U-Boot>
mmc dev 1
mmc1(part 0) is current device
U-Boot> mmc part
## Unknown partition table
mmc read ${loadaddr} 0 1
MMC read: dev # 1, block # 0, count 1 ... MMC: block number 0x1 exceeds max(0x0)
0 blocks read: ERROR
I'm sure that the mmc have a partion, I have done it from kernel (where the mmc work good).
I have this MMC:
The config is:
#ifdef CONFIG_CMD_MMC
#define CONFIG_MMC 1
#define CONFIG_GENERIC_MMC
#define CONFIG_IMX_MMC
#define CONFIG_SYS_FSL_ESDHC_NUM 2
#define CONFIG_SYS_FSL_ESDHC_ADDR 0
#define CONFIG_SYS_MMC_ENV_DEV 0
#define CONFIG_DOS_PARTITION 1
#define CONFIG_CMD_FAT 1
#define CONFIG_CMD_EXT2 1
/* detect whether ESDHC1 or ESDHC3 is boot device */
#define CONFIG_DYNAMIC_MMC_DEVNO
#define CONFIG_EMMC_DDR_PORT_DETECT
#define CONFIG_EMMC_DDR_MODE
/* port 1 (ESDHC3) is 8 bit */
#define CONFIG_MMC_8BIT_PORTS 0x2
#endif
The for esdhc_gpio_init is:

Have any suggestion?
Hi Cristian
this error may be caused by wrong image, generated for
other board. Had you tried with FSL BSP
L2.6.35_11_09_ER_SOURCE 
: Linux 2.6.35 Source Code Files and documentation
11.09. Supports MCIMX53-START and MCIMX53-START-R.
L2.6.35_11.05_ER_SOURCE : Linux 2.6.35 Source Code Files and documentation
11.05 for i.MX53 SABRE Tablet.
Best regards
igor
Hello,
I'm not sure if I understand your suggestion.
I have a custom board, based on LOCO (one ram bank etc), but there is mounted on an MMC as in the schematic posted.
I tried all u-boot present in MFGTOOL profiles, but only loco start, but the emmc don't work.
The IMX connection to MMC are:
And is really close to quick start board:
The Quick start board mount an mmc, and have WP and CD pins.
Regards
