Before posting I read a lot of message in this forum and in others.
I run Dynamic C 10.11 with a RCM4100. Today, I have programmed several times the module on my own board composed of a 3V3 power supply, a LED connected to PE1 and nothing else. The /reset in is unconnected as it is tied-up by R27 on the module itself.
I wrote a simple program to flash the led and it works fine. After several programming cycle I can’t connect to the processor anymore. The IDE returns error while is sending Cold Loader.
If I remove the programming cable the led flashes as expected, so the module is running. Furthermore:
both primary and RTC clock are running
power supply is present
checked the PROG connector rather DIAG
checked the right COM port on laptop
turned off, turned on after 1h: same error
If I move the module from my board to the Rabbit DevBoard I can program it. Thus, I guess there is a problem with my board… But why I was able to program before?
The I/O lines were connected to a pin header for test purpose. Please note that nothing was connected to the header. The wires length was about 1,5 inch.
Well, I had to break wires that were the same of programming lines. Then it worked again.
hi this is swamy from India.i am working on RCM 3000 . it"s my own design .Based on RCM3100 core module. here i am getting one prob .
1.I am unable to programme the RCM3000 after few programing cycles . it is showing the error “while sending pilot bios target communication error” pls help me to come out of this prob .
a) one thing i have observed that same unit work for some times in that time the cs1 pin of the
RCM3000 is low. CS1(chip select of the RAM).
b)And same pin will be high when it is unable to programme.
pls my i know on which condition the cs1 pin will be high.
