adsp2181 boot from PROM - Steve Conner - Sep 26 8:57:00 2003

>PROM..

It looks like you're doing all the right things with the assembly and
linking. I used the same command line options as you on my last project
(except I used spl21 -i for Intel hex format)

*These are the exact commands I used
asm21 intvec -2181 -c
asm21 main -2181 -c
asm21 uart -2181 -c
asm21 codec -2181 -c
asm21 utility -2181 -c
asm21 command -2181 -c
asm21 selftest -2181 -c
ld21 -i linklist -a ezmon -e ezmon -g -x
spl21 ezmon ezmon -loader -2181 -i
*

Then I renamed the ezmon.bnm to ezmon.hex and loaded it into my prom burner.
The DSP booted first time :-0 So it might be something else..

Are you generating the same format of hex file that your prom burning
software expects? spl21 gives Intel hex with the -i option and Motorola
S-Records without.

Do you have the BMODE and MMAP pins on the 2181 tied to ground? BMODE must
be low to tell it to boot from ROM.

Is your PROM chip wired to the DSP correctly (no address and data lines
mixed up etc)

There were also some bug fixes.

What are the dates of your tools files? Al Clark
