On uboot 2009.08 is ok,when I update to uboot 2015.04,is report this issue.

[igorpadykov]

please refer to sect.6.2 Manufacturing Tool, MFGTool attached Yocto

Guide from L4.1.15_1.1.0 package (uses uboot 2015.04)

Hi

please check that is used correct version of MFG Tools

Programmers (Flash, etc.) (12)

IMX6_M6.0.1_1.0.0_MFG_TOOL (REV M6.0.1_1.0.0)

i.MX 6 Family Manufacturing Toolkit for M6.0.1_1.0.0 (3.14 kernel)

http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/i.mx-applications-process...

Then use appropriate *.vbs file for each boot device and processor, for example for i.MX6Q Sabre SD SD card:

mfgtool2-android-mx6q-sabresd-sd.vbs

for eMMC:

mfgtool2-android-mx6q-sabresd-emmc.vbs

Best regards

igor

Hi igorpadykov:

Mfgtools version is correct.the boot device is emmc , double click mfgtool2-android-mx6q-sabresd-

emmc.vbs under mfgtools to flash the firmware .I also modify the cfg.ini

name = eMMC-Android 

mmc = 3

modify the Device Configuration Data in the bootable/bootloader/uboot-imx/board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg that verify on the uboot 2009.08.

what should I do another?

[igorpadykov · Accepted solution]

if you changed mx6q_4x_mt41j128.cfg, then it is necessary to rebuild mfg tools:

bitbake fsl-image-mfgtool-initramfs

The document Manufacturing Tool V2 Linux or Android Firmware Development Guide V2.docx say

How to Configure U-Boot and Kernel Image for MFG.

On the android 4.4.2 ,it can do like this :

make mx6q_sabresd_mfg_config

make

To build the uboot.bin for mfgtools.

On the android 6.0.1,what should I do to build the uboot u-boot-imx6qsabresd_sd.imx for mfgtools without yocto?

what is the different between the config,Could you give the patch?Thank you !

How to build MFG Firmware for i.MX6Q  I find that this is the method build uboot(v2009.08) for mfgtools,but how to rebuild mtftools firmware on the new uboot (2015.04)?
