HPPCI + ADSP-BF533 EZLITE + Video: Problems
Started by ●April 16, 2005
Hi,
I'm trying to run a small demonstration aplpication on which I
capture images from a camera trough the video codec on the ADDS-
BF533-EZLITE (rev 1.1, silicon rev 0.1).
This behavior happens both with VisualDSP++ 4.0 and 3.5 Nov'04
update, and if using HPPCI emulator:
The program loads fine. I can start to run it. But the PPI interrupt
never comes back. If I try to halt the DSP, I get the following
messages:
JTAG scan failed - Check target power and emulator connection.
Failed getting full context from the target.
Error writing user opcode for breakpoint remove at address:
0xffa0327c.
JTAG scan failed - Check target power and emulator connection.
Failed getting full context from the target.
Error Getting PC after Halting.
JTAG scan failed - Check target power and emulator connection.
Failed getting full context from the target.
JTAG scan failed - Check target power and emulator connection.
Failed getting full context from the target.
The most strange thing is that it works absolutely flawlessly with
the slow EzKit USB link!!! I wanted to use the emulator to get the
processed images faster, but does not nork.
I am using the HPPCI in legacy mode. Will I need to change to High
Speed mode?
Has anyone experienced similar problems? Any workaround that you
know of?
Kindest regards,
JaaC
