Mfgtool source for 3.10.17

manjunathjoshi — Tue, 21 Jul 2015 04:53:49 GMT

Hello All,

can anyone tell me where is the source for Mfgtool 3.10.17 for u-boot.

In ucl2 file,

we have,

....

<CMD state="BootStrap" type="boot" body="BootStrap" file ="firmware/u-boot-imx6q%board%_sd.imx" ifdev="MX6Q">Loading U-boot</CMD>

....

This u-boot considers default 1GB ram but our board has 2gb ram. So i want to modify source code and use the MfgTool.

Regards,

Manju

Hi Manjunath

please look at attched Yocto User Guide sect.6.3 MFGTool.

The manufacturing defconfig is imx_v7_mfg_defconfig and this is required

for the fsl-image-manufacturing image for the manufacturing tools support.

Yocto building is described on

Freescale Yocto Project main page

Best regards

Hello Igor,

Thanks for your reply.

Building imx_v7_mfg_defconfig will give us uImage with Mfgtool support. That's fine.

But for our board each time we flash and reboot, the u-boot is default 1GB ram which is same as the Mfgtool's u-boot. But if you see the Mfgtool directory structure, "files" directory contains the images to be flashed.

That's exactly not happening for "u-boot" only.

uImage and filesystem are flashed okay but not u-boot.

My guess was that, once the DDR is initialized with 1GB ram, even though i tried flashing 2GB configuration u-boot, the MFGtool is not able to flash that.

That's why i wanted to try this method.

What i want is, the source for u-boot with which the MfgTool u-boot is configured with.

Hi Manjunath

uboot can be built separately please refer to attached Porting Guide

Chapter 1 Porting U-Boot. DDR configuration is defined in

..include/configs/mx6qsabresd.h,mx6qsabresd_mfg.h,mx6_common.h
