Generate a signal on MOD5234 druing start up   Message List  
Reply | Forward Message #6207 of 6234 |
Hello there.

I have few questions about MOD 5234.

I am using MOD5234 to program my FPGA.
For this, I generate the PROGRAM PULSE so that the configuration process will
begin inside FPGA.

I am successfully able to do that.

However the problem is :
1. It takes 5-6 seconds before the PROGRAM pin goes low for 1 second.
I want this PROGRAM pulse to occur as soon as NB is powered up.
Does NB takes 5 seconds to boot up?
Because generating the PROGRAM pulse is the first thing I am doing
in my code.(thats what I think). Maybe there is something I am
missing.
(I am using MOD5234 J2-pin38 as PROG PIN which is connected to
FPGA PROG pin.)


2. Also the CCLK, (again generated by NB on J2-pin29) going to the FPGA is about
200Khz. How can I generate a clock in MHz using the NB timer or is there any
other method to generate a clock (which will act as CCLK for FPGA in the range
of 2-5MHz)

NOTE: The FPGA is being programmed here as in SLAVE SERIAL MODE.

Any help in this regard will be appreciated.
Thanks.

Hello, The 5-6 second delay from power up to the start of execution of your code is the time the NB monitor program is running. It waits 5 seconds to give you...
