Would you have a git tree with all the required Buildroot patches to get a bootable imx8mm image? Thanks, Fabio Estevam

What board are you exactly asking for? the nxp imx8mm evk? I have a tree for the kontron pitx-imx8m [1] that has an i.MX8MQ. Maybe this also answers your question ;-/ [1] https://github.com/hthiery/buildroot/tree/uboot-imx

Here we use a boot script. But other than that can use e.g. extlinux. I think this is not a candidate we can make generically. > board/kontron/pitx-imx8m/post-image.sh This calls the genimage. This could be removed and added directly into the defconfig as BR2_ROOTFS_POST_IMAGE_SCRIPT. > board/kontron/pitx-imx8m/genimage.cfg Here I', not sure. Because it depends on the used bootmethod how the image should look like. E.g. do we need to have a boot partion on not.

I've tried this series with our U-Boot (2020.07 based) and it doesn't work for me as using UBOOT_FORMAT_CUSTOM isn't sufficient as it only copies the binaries selected but doesn't use it as target [1]. So I wonder, which U-Boot version are you using? Is the flash.bin created automatically when issuing 'make all'? In my version of U-Boot it requires to use 'make flash.bin' otherwise it simply doesn't generate flash.bin. I believe we would still need a new U-Boot target name [2] but I'd like to understand how it worked for you Regards, Gary [1] https://github.com/buildroot/buildroot/blob/master/boot/uboot/uboot.mk#L135 [2] http://patchwork.ozlabs.org/project/buildroot/patch/20201125183017.15585-5-xroumegue@gmail.com/

So in your case when you use the "old" u-boot way of creating this output we have to add a new u-boot target in buildroot.

Indeed I just saw in your U-Boot tree how the binman description was done, it's pretty neat. So do you know if the flash.bin target is here to stay in U-Boot or is binman to new way to go and flash.bin becomes an outdated target? I know it's more of a U-Boot question than Buildroot but just to understand if it even makes sense to add the target if it's going to disappear in upcoming releases. Regards, Gary

As far as I understand the goal is to switch to binman for all boards. That would mean the flash.bin target will disappear. But what about having a custom build target in buildroot?
