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.
Regards,
