EMMC BOOT

[jeffery]

Now we are developing android 8.0.0 using imx6q board,and is successful to build the android image.

But  usiing mfgtools to download images,it appear to " Jumping to OS image. "

Because we use emmc boot ,so I think we should modify u-boot to emmc boot in android o source code,but it doesn't work.

How to modify to emmc boot?

thanks!

Hi 贻才 林 

such error happens when manufacturing firmware (files in mfg tools /firmware folder)

were not rebuilt for custom board. Steps are described in sect.6.2 Manufacturing Tool, MFGTool

attached Yocto Guide. Also had board passed ddr testi.MX6/7 DDR Stress Test Tool V2.90 

and boot linux. New calibration coefficients found from test should be put in uboot/board/..mx6sabresd

/mx6q_4x_mt41j128.cfg file and image should be rebuilt.

Best regards
igor
