Q7-IMX6 # version

U-Boot 2013.07.Q7_IMX6-13.12.01 (Nov 29 2013 - 17:51:25)
arm-poky-linux-gnueabi-gcc (GCC) 4.7.2
GNU ld (GNU Binutils) 2.23.2

I have tried to modify MEMSIZE parameter. Kernel doesn't boot if I force 
a value greater than 1024. My module contains 2GB of RAM.

I have tried to add in my kernel conf :

#
# Relocate loaded kernel to second GB of memory.
#
no makeoptions  KERNEL_BASE_PHYS
no makeoptions  KERNEL_BASE_VIRT
no makeoptions  BOARDTYPE
makeoptions KERNEL_BASE_PHYS="0x80000000"
makeoptions KERNEL_BASE_VIRT="0x80000000"
makeoptions BOARDTYPE="cubietruck"

I only obtain :


 Q7-IMX6 # go 0x80000000 




## Starting application at 0x80000000 ... 




  PC=0x80000020 




  SP=0x8f733e08 




CPSR=0x600001d3 




<cortex_init>@ABC12-</cortex_init> 




<mmu_init_table></mmu_init_table> 




<arm_cpuinit>FG01H1IJKL

	If I add MEMSIZE=2047, kernel hangs with exactly same message.

	Best regards,
