Can not see any infomation on the console when using U-Boot 1.0.0 booting my board
hi,
I am now porting U-Boot 1.0.0 to my custumized board with mpc8240.
My reference board is Sandpoint X2.
First I created my u-boot.bin for Sandpoint X2 as following:
$make Sandpoint8240_config
$make all
and Sandpoint X2 was booted smoothly.
Then I modified the serial port information in~~/u-boot1.0.0/include/configs/sandpoint8240.h because the serial port address on my board is different from that on Sandpoint X2. Below are my modification:
#define CFG_NS16550_CLK 24000000 /* 1843200 */
#define CFG_NS16550_COM1 0xff600000 /*(CFG_ISA_IO + CFG_NS87308_UART1_BASE)*/
#define CFG_NS16550_COM2 0xff600040 /*(CFG_ISA_IO + CFG_NS87308_UART2_BASE)*/
Other parameters are not modified.
After "make" and "burn u-boot.bin in flash" I reset my board
and I saw nothing on my console:(
Any suggestion? Thanks in advance.

You should rather create your own board config file.

Well, what do you expect? Remote debugging through a telepathy link?
Obviously your changes are wrong and/or insufficient to make U-Boot work on your baord.
Attach your BDI2000, fire up GDB and check what's going on there.
