Please can you explain me where the u-boot starts execution ? meansnot address. In source code which line or file executes first?
U-Boot starts at the reset vector; in code, see label _start in arch/powerpc/cpu/mpc8260/start.S
To enable console on SMC( There are 2 SMC in MPC8280, we using SMC2 means Pin no. PA9 ( Tx ) and PA8 (Rx) ). I modified as follows
+ /* PA9 */ { 1, 1, 0, 1, 0, 0 }, /* SMC Tx */ + /* PA8 */ { 1, 1, 0, 0, 0, 0 }, /* SMC Rx */
*/ +#define CONFIG_CONS_ON_SMC /* define if console on SMC */ +#undef CONFIG_CONS_ON_SCC /* define if console on SCC */ +#undef CONFIG_CONS_NONE /* define if console on something else */ +#define CONFIG_CONS_INDEX 2 /* which serial channel for console */
+#define CONFIG_HARD_I2C 1 +# define CFG_I2C_SPEED 50000 +# define CFG_I2C_SLAVE 0xFE
+/* system clock rate (CLKIN) - equal to the 60x and local bus speed */ +#define CONFIG_8260_CLKIN 100000000 /* in Hz */ + +#define CONFIG_BAUDRATE 115200
Still am not getting any think on console, The SMC ports are inbuilt, it needs any serial driver to modify or any other files? Please suggest me to come out of this problem.
