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); } ========================================= ==========<cut board.c>================== #include <common.h> #include <environment.h> #include <fcntl.h> #include <platform_data/eth-fec.h> #include <fs.h> #include <init.h> #include <nand.h> #include <net.h> #include <partition.h> #include <linux/sizes.h> #include <gpio.h> #include <mci.h> #include <generated/mach-types.h> #include <mach/imx53-regs.h> #include <mach/iomux-mx53.h> #include <mach/devices-imx53.h> #include <mach/generic.h> #include <mach/imx-nand.h> #include <mach/iim.h> #include <mach/imx5.h> #include <mach/esdctl.h> #include <asm/armlinux.h> #include <io.h> #include <asm/mmu.h> ........ other device init functions ...... static int myboard_init(void) { imx_esdctl_disable(); arm_add_mem_device("ram0", MX53_CSD0_BASE_ADDR, SZ_512M); return 0; } core_initcall(myboard_init); ======================================== Thanks in advanced. _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
