Failed to use MfgTool for i.MX6 with Yocto Project

[yuhuiliu1]

We want to upgrade from i.MX6 DualLite to i.MX6 QuadPlus.

In i.MX6DL, we used i.MX Yocto Project BSP with imx-4.1.15-2.1.0.

In i.MX6QP, we also used the same setting.

We built image in the following commands:

$ DISTRO=fsl-imx-wayland MACHINE=imx6qpsabresd source fsl-setup-release.sh -b build-image

$ bitbake fsl-image-qt5-validation-imx

Then flashing image to sdcard:

        $ sudo dd if=fsl-image-qt5-validation-imx-imx6qpsabresd-20191209095719.rootfs.sdcard of=/dev/sdb bs=1M conv=fsync

We used this sdcard on i.MX6QP but didn’t work. (nothing happened on i.MX6QP)

We used another way – MfgTool but stock at loading U-boot for a long time.

Hi yuhuiliu@luxvisions-inno.com ,

We are able to build  L4.1.15-2.1.0 image for  i.MX 6QuadPlus Sabre board and boot i.MX 6QuadPlus Sabre board using L4.1.15-2.1.0 sdcard image. So can you please try to compile u-boot image and try to boot board using only u-boot image. make sure that your boot mode switches are correct to boot from sd card.

Regards,

Radhika Somaiya.

Hello,

It seems that the image is missing uboot, please try by copying the bootloader directly to your SD

$ sudo dd if=<u-boot image> of=/dev/sdx bs=512 seek=2 conv=fsync

Hope this helps,

Regards,

Aldo.
