ROM booting - raja nayaka - Oct 28 8:49:00 2002




We are using Tms320C6211 DSP under 8 bit ROM boot configuration
CE1 space,ie HD[3]-HD[4] being {1,0}.
Iam testing the CE1, Data Bus and Address bus of ROM
I have the following observations.

(1) Once I make the #RST low , the CE1 and Address
bus of the ROM remain high and Data bus remain low.
(2) Once I remove the #RST , I find CE1 going low and then
high , while the the status on ROM address bus goes low but
thers no change in the status of Data bus

As the DSP makes a load of 1k from the ROM
to the on -chip memory the address and data bus
should pulse to make the necessary load, but thats
not happening. Pls provide some valuable suggestions in this regard.
Also provide some info abt the reading material
regarding the BOOT PROM and writing the linker files
for the same.
