Hi Fabio,

I'm seeing some issues with some of the i.MX6 devices with the latest stable release. It loads the SPL and then just seems to loop:

U-Boot SPL 2017.09 (Sep 25 2017 - 18:42:10) Trying to boot from MMC1

U-Boot SPL 2017.09 (Sep 25 2017 - 18:42:10) Trying to boot from MMC1

U-Boot SPL 2017.09 (Sep 25 2017 - 18:42:10) Trying to boot from MMC1

This is built on Fedora with latest gcc7 so I'm not sure if that's a possible issue. Is this something people are aware of and I've missed the fix.

I haven't tested it with gcc7 yet, but if I use gcc6 I do not see the problem:

U-Boot SPL 2017.09 (Sep 25 2017 - 15:55:59) Trying to boot from MMC1

U-Boot 2017.09 (Sep 25 2017 - 15:55:59 -0300)

So maybe this issue could be related to gcc7?

I've tested building U-Boot for Wandboard using GCC 7 from linaro.org: https://releases.linaro.org/components/toolchain/binaries/

I've used this package: gcc-linaro-7.1.1-2017.08-x86_64_arm-linux-gnueabi.tar.xz

I could not reproduce your error. It seems to work on my board, here is the log:

I tested a build with 6.4 from Fedora 25 and I saw the same issue so I'm not sure where the problem is coming from but I'm also travelling/meetings so haven't had time to dig further into the issue

In the meantime I have also built U-Boot 2017.09 for wandboard with gcc7.2 from Buildroot and it boots fine.

If you find out more about the problem, just let us know.
