BDI2000 with PPC405EP

BDI2000 with PPC405EP

[Albert David]

Friends,
I have been trying to find a solution to fix "PPC: timeout while
waiting for freeze" for my custom board.
BDI2000 keeps resetting the system with the following message...

TARGET: processing user reset request
TARGET: resetting target passed
TARGET: processing target startup ....
*** TARGET: core #0 startup failed # PPC: timeout while waiting for freeze
TARGET: target will be restarted in 10 sec

I tried all the possible solutions provided at
http://www.ultsol.com/faq-P206.htm for this perticular behaviour but
the problem remains same!

I have ensured that my Board's JTAG interface is properly working by
boundary scanning the pins of PPC405EP using UniversalScan software
with Altera-ByteBlaster MV.

for your information: twice i could succeed connecting BDI2000 with my
target! somehow it happen to work while i was trying to execute low
level JTAG commands such as 'rir' rdr'  and then after exiting(JTAG
command shell of BDI) it worked, but there is no consistency!

looks like my cpu core is not halting after asserting HALT line.
has anyone faced similar problem??

please help!
BR,
Albert David.

In _all_ cases I saw this problem it was a hw bug. Ask your hw 
engineers to help you. Start with the usual suspects: power, clocks, 
strapping, etc.

I don't think working boundary scan is an indication that hw design is 
OK.

Dear Eugene,
Thanks for your suggestion! This was indeed a hardware bug! I found a
problem with my cpu strapping pins! UART0_TX was never driven
externally(it was left open),
Thanks again for your reply,
with best regards,
Albert.
