provided SPL prevents Linux from booting

Hello all, I'm attempting to do some work at the SPL/U-Boot level, and am finding that when replacing the SPL preloader, it boots U-Boot OK, but when U-Boot passes control to zImage, it hangs. ...

Sorry I don't have a debugger script for you. However, if you have the SoC-EDS Arm DS-5 license, you should be able to debug this problem using the HPS JTAG port.

It looks like the SPL source code base is the exact same version (2013.01.01) but I suppose when you rebuilt it, the environment was a bit different (no CLOCK setting printed out). Maybe you can turn on debug prints for another SPL build? I tried it once and the image turned out to be too big so it failed. Maybe it will work for you? You can also add in your own printf statements.

So, at the point where Uboot says "Starting kernel", there's no indication that the zImage file was located (or not). Can you verify it's in the right place based on your BSP editor settings? I'm wondering what Uboot says when it can't find the zImage. Maybe try deleting the image on purpose to see what happens?
