Hello Group Members
I am trying to build a simple system consisting of PowerPC405, JTAG, UART, OPB DDR controller, and 16MB External DDR memory on a HiTech PPC board. No on-chip BRAMs. I use EDK 9.1/ISE9.1 versions.
If I try to launch XMD from EDK GUI, it prints messages detecting the programming cable and quits without printing any error messages.
I tried invoking XMD from cygwin shell and used the command ' connect ppc hw', it detects the JTAG chain, prints the ID code and then quits printing 'ERROR(0):'. I have no idea what might be wrong here.
Any help is very much appreciated.
Interestingly, If I use only on-chip BRAM and no external memory, i can print messages to UART by downloading code through XMD.
Thanks swamy
