uImage in Yocto project not generated

disheng — Wed, 07 Apr 2021 08:05:27 GMT

Hello,

I have the Yocto project for L3.14.52_1.1.0_ga setup for imx6qsabred board and by running:

bitbake fsl-image-mfgtool-initramfs

I can see there is zImage_mfgtool generated but no uImage,
and I added

KERNEL_IMAGETYPE = "uImage"

to imx6qsabresd.conf and manage to generate a uImage.bin file, but not "uImage" which I can use in the mfg tool.

Question:
1. is the uImage.bin same as "uImage"? Can I use it directly in the mfg tool?
2. if not, how do I generate a "uImage" file in Yocto project?

Thank you,
Di

why do you need to use uimage? mfgtool can download zimage directly

Hello Joan,

I figured that out afterwards... Thanks.

Now when we try to use mfgtool to flash, it gets stuck in the kernel and it seems to have unmatched machine id.

The id passed by uboot is f8c which is correct for imx6q, but the ids in kernel seems strange, all "ffffffff", do you know what can be wrong?

Regards,
