kingplayer — Wed, 22 Aug 2018 07:48:40 GMT

hi nxp,

I want download zImage from ftp,and use nfs,but only Image build on imx8mq by defalut Yocto Project;

I changed imx-base.inc, KERNEL_IMAGETYPE_mx8 = "Image"
to KERNEL_IMAGETYPE_mx8 = "zImage", then build error!

build log:

Hello Kingplayer,

You would need to setup zImage as KERNEL_IMAGETYPE on the MACHINE configuration file for your board. The zImage is not defined for the i.MX8m which is why it’s prompting an error. I haven’t tried enabling it though, but it should be possible.

I hope this helps!
Regards,

Hi,

No, it isn't possible to build a zImage for ARM64 platforms (such as the i.MX8MQ).

That is because it was decided in Linux not to add zImage support, so there's no way around it.

An alternative is to compress the Image file (Image.gz) and then have the bootloader uncompress it before jumping into it.

Regards,

Gary
