There is a boot anomaly for parallel booting that is descibed on the ADI 
web site.

I have never used a parallel flash boot for a 3rd generation SHARC. 
Frankly, I don't know why anyone would want to since all of these devices 
support booting from serial flash. The serial flash is a small 8 pin part 
versus 32 pins for a parallel flash.

Well actually 21369. We have a few boards that we are going to install 
21375 parts on soon. The 21375 and 21371 are just being released.

You are talking about ADSP-2137x?


Thanks for your help.

None, that I know about.

We use serial flash for booting.

And how many that are having problems? ;)

I have no problem now because I never use ADSP-2137x but I want to. :)
I asked this question, because someone told me that he had some problem
with a SHARC DSP. I don't remember exactly what he said, something about
not working a booting method. He said also, that this kind of problems are
typical for new SHARC (early revision).

Yes

What problem are you concerned with? We have many ADSP-21369 customers that 
are not having problems. My understanding is that the 2137x is working very 
well.

I have a few question about AD SHARC DSPs.

1. I read ADSP-21375 datasheet but I still don't know whether I can use
DATA port as General Purpose IO? This question concerns also
ADSP-21367/8/9.

2. I heard that all new SHARC DSP (early revision) have some mistake. Is
that true? I want to use ADSP-21375 which is quite new and I don't know
whether that safe is. I don't want a situation that I make PCB, bay
processors and it turns out then that for example some booting method
doesn't work.
