Fabio, Vincent,

The freescale_imx31_3stack_defconfig in Buildroot no longer builds, because the Linux kernel version used in this defconfig is too old, and doesn't build with gcc 5.x.

Has one of you access to this platform, and be willing to update this defconfig?

See
http://free-electrons.com/~thomas/pub/buildroot-defconfigs/freescale_imx31_3stack_defconfig.log.FAIL
for the full build log.

Thanks!

Thomas

I think we should be able to use the latest mainline on mx31pdk.

I will try to get access to a mx31pdk and will give it a try with latest mainline.

Thanks

Great, thanks!

Bonus point for other improvements to the defconfig, such as adding the build for the bootloader, etc :)

Thanks,

Yes, I thought about that as well. Mainline U-Boot should also boot fine on this board, so hopefully I will be able to test it next week.

Thanks

Hi Thomas and Fabio,

I am sorry to say that I don't have access to an i.MX31 PDK anymore. The one I used by the time was already a "rare" resource in Freescale France :)

I will try to help repair the build at least.

If this platform is difficult to get access to, and rarely used, then maybe we should just remove the defconfig in Buildroot? It doesn't make a lot of sense to have defconfig for platforms that are not in use.

Best regards,

Thomas

Yes, even for me it will be difficult to get access to a mx31pdk board, so I am OK with removing its defconfig from Buildroot.

PATCH 1/1 configs: freescale_imx31_3stack: bump kernel version to 4.1.15_2.0.0_ga

In reply to Thomas Petazzoni

From: Vincent Stehl? <[email protected]>

Switch to the kernel of release 4.1.15_2.0.0_ga, as it builds properly with gcc 5.x, which is now the default.

We add a linux config fragment to disable the framebuffer, to repair the build for imx_v6_v7_defconfig.

Hello Thomas and Fabio,

My friend Julien got the i.MX31 PDK and he could kindly test a few buildroot configs!

His experiments show that mainline kernel will not boot "as is" on the PDK. What he proposed instead is that we switch to a recent NXP/Freescale release based on kernel 4.1, which does boot on the PDK.

Is that proposal fine with you, please?

Best regards,

Vincent.

Thanks a lot! I've applied to master, with one minor change.

It is more conventional to write this as:

# CONFIG_FB_MXS is not set

which is what kconfig generates in a defconfig for an option that is disabled.

Thanks!
