Subject: Re: Configure RAM size on iMX53 board
To: barebox@lists.infradead.org

Thanks Sascha, but something I do wrong

I tried set fixed size to 512M, but neither works.

With these changes does not work or 512MB board  or 1GB board.

=========<cut lowlevel.c>===============

#include <common.h>
#include <mach/imx53-regs.h>
#include <mach/esdctl.h>
#include <mach/generic.h>
#include <asm/barebox-arm-head.h>
#include <asm/barebox-arm.h>

void __naked barebox_arm_reset_vector(void)
{
    imx5_cpu_lowlevel_init();
    arm_setup_stack(MX53_IRAM_BASE_ADDR + MX53_IRAM_SIZE - 8);
//    imx53_barebox_entry(NULL);
    barebox_arm_entry(MX53_CSD0_BASE_ADDR,SZ_512M,NULL);
}

Thanks in advanced.
