Hey Portisch,

Thank you very much! I fixed it with your "standard-fixed-uboot". I had to understand that the uboot-file is not loaded from the sd (so not the FILE u-boot.bin) but from sector 0 on the sd. after dd-ing the ...sd.bin on the sd it booted rightaway and I burned the u-boot.bin (from you) to the flash as discribed in the post from BUMERC

Is the new U-Boot you provided above any better?

The PCB was green and the lable said "CZ | 2G - 16G | 9377" (from memory since my case is already closed)!

So thanks again, now I will test the Poweron-Issue!

As far as I understand it, the u-boot might use the wrong RAM-timing, right? Any suggestions how to fix it?

Thanks in advance!
