This is my serial debug messages , I use the uboot and uImage in the mfgtools.

I want to know whether I should rebuild uboot and uImage again! if not why I cant not partition my eMMC and always failure

Hi jun,

Would you please tell us which board and which BSP are you using? You want to download image to board, using the default uboot and uImage in mfgtools is ok. I wonder what have you modified when you download. So It's hard to detect where's the problem.

Hi Dan,

Thank you for your responding.What I have changed is that my emmc use USDHC-3 but not USDHC-4,so I config the CFG2_4:CFG2_3=10, I think it wil be ok. and my board is reference SabreSD, my cpu is i.MX6DL.

Hi Dan,

When I was reading the "Manufacturing Tool V2 (MFGTool2) Linux or Android Firmware Development Guide" in the MFGTools document,I cant found something. There is one chapter say "How to Generate U-Boot and Kernel Image for MFG Please refer to the BSP User Guide, chapter Build Manufacturing Firmware." My problem is that i cant find where is the document which name is "the BSP User Guide".Because I really want to read more details about Building Manufacturing Firmware,I also search it on freescale's website,but I still cant find.Could you please tell me where I can get the docoument which introduce how to building Manufacturing Firmware.Thank you!

Best Regards

Hi Jun,

The document is in the L3.0.35_4.1.0_LINUX_DOCS. Here I can attach to you. The document name is i.MX_6Solo6DualLite_SABRE-SDP_Linux_User's_Guide.pdf. And the 3.9 Building Manufacturing Firmware is what you need. By the way, you also can select Build mfg firmware in LTIB.

Hi Dan;

     I hava the same problem, my board's emmc connect to  SD4_DATA0 - SD4_DATA7,SD4_CMD,SD4_CLK, and I download Mfgtools-Rel-4.1.0_130816_MX6DL_UPDATER,

     in the ucl2.xml, I add the command;

     <CMD state="BootStrap" type="jump" > Jumping to OS image. </CMD>   

     <CMD state="Updater" type="push" body="$ ls -l /dev/mmc* ">ls /dev/*</CMD>

     but there is no /dev/mmcblk0 device

     In my Android bsp, I used mx6dl_sabresd_mfg_config to generate mfg uboot, used imx6_updater_config to generate mfg uImage

     Is it correct? and how to modify the code to adapt to my board?

     thanks!

Hi jun,

As you are not using freescale's boards, so you have to build uboot and uImage according to your own board. I thought you are using freescale's board. So you can have try after you build the BSP according to your boards.
