hi,
Has any one make u-boot-1.1.6-2008R1.5 to BF531 board successfully?
My board is bf531-0.4
and i turn on the serial_early_puts functon in cpu.c
but i can only get the message of:
UBOOT> go 1000000
## Starting application at 0x01000000 ...
Early:start.S: Init Registers
Early:start.S: Relocate
Early:start.S: Zero BSS
Early:start.S: Lower to 15
Early: NOP Slide
Early: L1 Relocate
Early: Board init flash
there is no message any more !!!
if my config correct, following the docs
docs.blackfin.uclinux.org/doku.php?id=bootloaders:u-boot:debugging
u-boot will run to step 3:
U-Boot initializes important services: lib_blackfin/board.c:board_init_f()
Initialize the Instruction and Data CPLB tables
Initialize exception callbacks
Turn on Instruction and Data caches (if enabled)
Initialize the global and board data structures
Initialize IRQ callbacks
but there is no message any more ........
my sdram is 32Megs, and flash is amd 28f160
who can give me some suggesstion???
thanks

Ch:
Maybe if you asked in the U-Boot forums - you might get some answers to your U-Boot question...

thanks, Robin Getz
I have found the question, which is in the file of lib_blackfin/board.c
int the func of board_init_f()
when call this func init_cplbtables() -->
icplb_add(CFG_MONITOR_BASE & CPLB_PAGE_MASK, SDRAM_IKERNEL);
dcplb_add(CFG_MONITOR_BASE & CPLB_PAGE_MASK, SDRAM_DKERNEL);
the program will die(~.~),
my CFG_MONITOR_BASE is 0x1fc0000,
can you give me some suggestion??

Ummm...
Like I said - no one is going to suggest anything on this forum - since it is not a Linux question. Go to the front page, on the table there - there is a U-Boot help forum. Go there - ask your question.
