Hi,

I am trying to port linaro u-boot on custom omap4 board. I can see it's booting and hanging after sdram_init. We are using different ram from panda. Panda uses Elpida we are using Samsung.

Following is the error I get

SDRAM : identified size is not same as expected size identified : 0 expected : 40000000

I checked in code and I could see that it is carrying quick memory test.

Previously I was using omapzoom u-boot and it was having following memory configuration

.sdram_config_init = 0x80000eb2, .sdram_config = 0x80001ab2, .ref_ctrl = 0x00000618, .sdram_tim1 = 0x10eb0662, .sdram_tim2 = 0x20370dd2, .sdram_tim3 = 0x00b1c33f, .read_idle_ctrl = 0x000501ff, .zq_config = 0xd00b3215, .temp_alert_config = 0xd8016893, .emif_ddr_phy_ctlr_1_init = 0x049ffff5, .emif_ddr_phy_ctlr_1 = 0x049ff408

This configuration is for Samsung 4G_S4 memory which is 1GB with only 1 chip select on each emif.

Please suggest inputs to debug.
