hi
the bootloader that i use is for custom board. the memory registers are 
all set up as on IDTsim.there is no real interrupt handling mechanism on 
the boot loader. The processor is actually 1dt 332 but ive mangaed to 
make necessary changes (port control widths etc etc).also CPU speed is 66 
The memory on board is 8MB SDRAM using bank 0 and bank 1. the board is 
based on the IDT board however.



i have made all necesarry changes to the support the board in all the idt 
header files itself. However im still no able to get redboot running. As 
of now im compling redboot with the ROMRAM option. Does redboot expect 
any initialisations before it runs..because i just use the redboot.srec 
image and burn it into my flash AMD flash.

my bootloader doesnt support any gdb tracing either.

Thanks,
Avinash
ps: here is a mem map....... of the board
--------------------------------------------------------------------------

* Region A (000000): Used by SDRAM
 * 		Width set to 10b (32 bit)
 * 		
 * Region B (000001): Not used
 * Region C (000010): Not used
 * Region D (000011): Not used
 * 		Width set to 10b (32 bit)

 * Region E (000100): Used by NVRAM, LED, EPLD
 * 		Width set to 00b (8 bit)
 *
 * Region F (000101): Used by Flash
 * 		Width set to 01b (16 bit)
