you mean it's not the problem of my console configuration but the u-boot
program?
But I thought it might at least output some message of the board before it can
output the prompt "=>",is that right? Listing all my chang in the TQM860L.h
may help:
#define CONFIG_CLOCKS_IN_MHZ 50 /*50Mhz osc connected to 860_EXTCLK*/
#define CONFIG_BOARD_TYPES 0 /*It's a simple board ,supported?*/
#define CFG_OR0_PRELIM 0xfff80920 /*boot flash is AM29LV040B,512k*/
#define CFG_BR0_PRELIM 0x40000401 /* magic numbers of my modify take
/*reference from a working vxworks
BSP's
/* romInit.s of the same board*/
/* #define SDRAM_BASE2_PRELIM 0x00000000*/
#define SDRAM_BASE4_PRELIM 0x00000000 /*cs4 is sdram*/
#define CFG_OR4_PRELIM 0xfe000f60
#define CFG_BR4_PRELIM 0x00000081
#define CFG_MAMR_11COL 0x10924111 /*11 col,here is the value I write to mamr
in tqm8xx.c*/
#define CONFIG_SCC1_ENET 1 /*should add a number?*/
/*#define CONFIG_FEC_ENET*/ /*no FEC*/
and in tqm8xx.c,I did like this:
1.changed upm_table according to my sdram;
2.modify the register's value in the function initdram()
