Booting from the eMMC

surendradhobale — Mon, 06 Mar 2017 09:01:04 GMT

Hello,

We are developing the custom board based on the imx6ul with eMMC.

We are looking eMMC as bootable device in the board. i.e uboot, kernel and FileSystem on the eMMC.

We are not using SD card interface for the development.

My question is,

1) In development, How i can update the uboot, kernel and Filesystem.?

2) How I can make the eMMC partitions ( as very initial no any partition on the eMMC) ?

Is i need to make the partitions in uboot ? How ?

Regards,

Surendra

Hello Surendra,

for image deployment you can use MFG Tool. All the documentation comes in the archive with it. For eMMC operations from U-boot, please refer to the Linux User's Guide.

Also please refer to BSP porting guide as you are developing a custom board.

Best Regards,

Jan

Hi Surendra,

besides the MFG-Tool there is also a quite handy procedure described for the WaRP7 board here:

Warp7 Yocto : Part2 : Flashing Warp7 binaries | element14 | WaRP7

1) You use the small Linux tool imx_usb to download an i.MX6UL u-boot binary

2) With u-boot you manage the rest

The WaRP7 board has no SD-Card as well, so in the support forum for this board you will find also some information about eMMC partitioning or fixing boot problems.

Regards,

Bernhard.
