I'm setting up a Linux system on a CycloneV on Atlas-SoC, and I'm using Yocto Pyro to build. I'm using meta-altera from https://github.com/kraj/meta-altera to build the kernel. The preloader and u-boot is built using Quartus 17.1 and EDS. I'm using meta-linaro and use Linaro GCC 6.3.
If I select KERNEL_PROVIDER="linux-altera-ltsi" which is now at 4.1.33, everything boots fine. However if I select KERNEL_PROVIDER="linux-altera" and version 4.12 or 4.11, I get failures in MMC, which ultimately fails the boot. Any ideas to why?
