we use an i.mx6ul on our custom board. till now we used a 512MB micron chip. now we changed to the MT41K512M16VRN-107 IT:P. It is a twin die chip with only one CS. But wenn u-boot calculate the memory automaticly it shows correct 1GB but the kernel didnt start. Kernel hangs after:
Starting kernel ...
Uncompressing ........ done, booting the kernel.
When we set the memory fix to 800MB it worked fine.
Where is here the problem?
We think something in uboot isnt correct?
