Hi, Cody,

From the booting log you provided, I didn't find eMMC device, It should be /dev/mmcblk0, So you have lost it! Please check your kernel configuration!

Regards,

Weidong

Re: MX6DL:Waiting for root device /dev/mmcblk0p1...

Yuri — Thu, 17 Apr 2014 07:14:43 GMT

Some accuracy is needed when configuring U-boot environment after deploying

images for SD / MMC and eMMC. At first glance - practically the same thing, only

MMC numbers are different.

From "i.MX_6Dual6Quad_Sabre-SD_Linux_User_Guide.pdf", section 9.2 (Run the Image from MMC/SD) :

For SD / MMC.

U-Boot > setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc dev 2; mmc read

${loadaddr} 0x800 0x2000;bootm'

Please pay attention - mmc dev 2.

For eMMC.

U-Boot >setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc dev 3;mmc read ${loadaddr} 0x800 0x2000;bootm'

Please pay attention - mmc dev 3.

So, please try to setup correct environment for SD/MMC (or eMMC).

Have a great day,
Yuri

Dear Yuri ：

I come across the problem by my custom board which is something different from demo board.

my board should use "mmc dev 2",else it can not run.

the attachment is different between the eMMC Storage of mx6DL-SDP demo board and my custom board.

SO which codes should I change?

Re: Re: MX6DL:Waiting for root device /dev/mmcblk0p1...

cody — Thu, 17 Apr 2014 08:40:33 GMT

Dear weidong.sun:

Thank you very much for your suggestion.

I have check kernel configuration,it is ok.

The same image can run in mx6dl-sdp board.

I find the difference of urat log between mx6DL-SDP demo board and my custom board is as following :

mmc0: new high speed DDR MMC card at address 0001

mmcblk0: mmc0:0001 SEM08G 7.39 GiB

mmcblk0boot0: mmc0:0001 SEM08G partition 1 2.00 MiB

mmcblk0boot1: mmc0:0001 SEM08G partition 2 2.00 MiB

mmcblk0: p1

mmcblk0boot1: unknown partition table

mmcblk0boot0: unknown partition table

So there must be something wrong with mmc.

Moreover , the attachment is different between the eMMC Storage of mx6DL-SDP demo board and my custom board.

From that ,we can see my custom board used the SD3 PIN,while mx6DL-SDP demo board used the SD4 PIN.

So where should I change?

Thanks.

Hello, Cody,

Please try to modiy BSP source code to register uSDHC3 port firstly! This can ensure eMMC iNAND Flash to be /dev/mmcblk0.

Please check Linux configuration as Weidong recommended,
