I used the u-boot code from ftp://micrel.com/ethernet/8692/8692-uboot.bz2

Changes made:

In my board am having two 32MB DDRs each with data width 32 bit. Total DDR memory will be 64MB

i run the command make ks8692_micron_166_config

Then i modified the include/config.h file as below ( since config.h is generated as read only, i changed the file permission before editing)

#define MICRON_166_DDR #define PHYS_SDRAM_1_SIZE 0x04000000 /* 64MB*/ #define KS8692_DDR_ROW_COLON_CONF DDR_256MBIT_BY_16 /* each IC is 256Mb with 16 bit data width */ #define KS8692_DDR_BUS_SIZE_CONF DDR_BUS_32BIT

/* Automatically generated - do not edit */ #include <configs/ks8692.h>

I made similar changes in include/configs/ks8692.h

Changed CONFIG_CONS_INDEX to 2 in include/configs/ks8692.h as i am using UART2

Changes in lowlevel_init.s (

1. Changed all UART1 to UART2

2. Changed ldr r4, =0x03000000 /* somewhere in DDR RAM */

to ldr r4, =0x01000000 /* somewhere in DDR RAM */

3. Changed ldr pc, =0x3000000 /* jump to DDR instruction */ to ldr pc, =0x1000000 /* jump to DDR instruction */

I compiled and dowloaded the u-boot.bin to flash. I am not able to see any prints in hyperterminal.

Hyperterminal was set for baudrate: 1152000

For debugging purpose i added the following lines just after serial init in lowlevel_init.s ldr r1, =KS8692_IO_BASE+KS8692_UART2_TX_HOLDING ldr r2, =65 /* alphabet A */ str r2, [r1]

ldr r1, =KS8692_IO_BASE+KS8692_UART2_TX_HOLDING ldr r2, =66 /* alphabet B */ str r2, [r1]

Now am able to continuous stream of ABABABABABAB......... in the hyperterminal.

Please help me to debug and fix the issue.
