IMX53 MMC3 on u-boot

cristiansicilia — Mon, 02 Nov 2020 13:12:58 GMT

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

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.

I would suggest to check if emmc is working at all with standalone test

IMX53_QSB_OBDS "On-Board Diagnostic Suit for the i.MX53 Quick Start Board"

Thank you,

I try it now!

But when I start linux kernel (loading it from SD CARD), I can manage the internal emmc normally

// SDCARD

mmcblk0: mmc0:aaaa SU08G 7.40 GiB

mmcblk0:

p1 p2 p3

// internal eMMC

mmc1: new high speed MMC card at address 0001

mmcblk1: mmc1:0001 002G49 1.82 GiB

mmcblk1:


// And do some operation on it

root@nsip ~$ mount /dev/mmcblk1p1 /mnt/cdrom/
root@nsip ~$ ls /mnt/cdrom/
ciao  lost+found
root@nsip ~$ echo vvvv > /mnt/cdrom/test
root@nsip ~$ umount /mnt/cdrom/
root@nsip ~$ mount /dev/mmcblk1p1 /mnt/cdrom/
root@nsip ~$ ls /mnt/cdrom/
ciao  lost+found  test
root@nsip ~$ cat /mnt/cdrom/test
vvvv

I tryed to enable trace in U-BOOT:

I tried to do the mmcinfo on eMMC, but I get only 0:

Device: FSL_ESDHC

Manufacturer ID: 0

OEM: 0

Name: Tran Speed: 0

Rd Block Len: 0

MMC version 0.0

High Capacity: No

Capacity: 0 Bytes

Bus Width: 1-bit

Current Partition for boot: Not bootable

And analyzing the SEND_CMD:2 dump:



                                        000 - 77 4F FB 4C   
                                        004 - 77 4F FB 70

                                        012 - 77 82 19 EE

seems don't match with the eMMC datasheet (attached).

Re: IMX3 MMC3 on u-boot

igorpadykov — Mon, 13 Apr 2015 09:58:17 GMT

in Uboot SDHC1 corresponds to dev 0

SDHC3 corresponds to dev 2

Re: Re: IMX3 MMC3 on u-boot

cristiansicilia — Mon, 13 Apr 2015 12:28:31 GMT

With this command I get an error:

U-BOOT> mmc dev 2

MMC Device 2 not found

no mmc device at slot 2

Consider that this is a IM53 not an IMX6.

And when I reset it show:

...

Boot Device: SD

I2C: ready

DRAM: 512 MB

MMC: FSL_ESDHC: 0,FSL_ESDHC: 1

...

And the fsl struct is:


struct fsl_esdhc_cfg esdhc_cfg[2] = {  
  {MMC_SDHC1_BASE_ADDR, 1, 1},  
  {MMC_SDHC3_BASE_ADDR, 1, 1},  
};

Re: IMX53 MMC3 on u-boot

cristiansicilia — Thu, 16 Apr 2015 08:01:50 GMT

I tried to add the SDCH2 due to shift dev to 2, but the result is the same.

Also using the u-boot for loco board in mfgtool the read on internal mmc don't work.

Any other suggestion?

Consider that:

A - The u-boot on eMMC is loaded correctly by the IMX53 ROM loader

B - The eMMC is used successfully with the kernel
