Got it.
If the address is not word aligned, the CPU outputs it as two 8 bit bytes instead.!!
Now just need the see if the LCD will respond now that the data is appearing on the bus.

Breakpoints not working
Hi all,
I have a simple test application just now and I can't get the debugger to stop at break points. The code is compiled as debug and I can see the debugger starting but it just carries on even if I insert break points.
Am I missing something in my build?
Cheers,
Dave...

Re: Accessing the external bus
Thanks Thomas, My databus is indeed connected to DB16-31 as this is what is brought out to the IO pins. I used to work with the MC68332 many years ago so learned to know about the use of the bus. At that time it was all in assembly!! :) I thought about using the word alignment. This is the confusing...

Accessing the external bus
Hi All, I have copied some code from the MOD5234 demo and tried to modify it for my memory configuration but I am not seeing the correct information on the logic analyser. This is the code I used. #define BASEADDRESS ( 0xA0000000 ) static volatile WORD *pDisplayCommand = ( WORD* ) (BASEADDRESS); sta...

Re: QSPI on the MOD5213
I don't have the MOD5213 but when I looked in the MOD5234\system directory I found a file called qspi.cpp and there is references within that to the MOD5213 so I guess this should also be in your installation too. Try looking in the Netburner installation directory under the MOD5213 directory. Good ...

Re: Coldfire Data bus.
Hi there, The issue with memory on the ISA bus is the lack of addressing range. As this is normally an IO bus, there is limited memory addressing range so you will have to do some trick work to do this. Most addresses are only 256 byte wide and there is only limited IO available, usuallly around add...

Re: Coldfire Data bus.
Dual port RAM but to be honest, this seems like overkill to have to design for ISA bus or even PCI for that matter. The ISA bus is only 8Mhz and PCI is 33Mhz but for PCI you need FPGA or use one of the PCI to ISA bus IC's out there to migrate easier to your ISA bus design. You still need to develop ...

Re: DisablePHY() gives error when compiling
It kind of makes sense too as you use the Ethernet for debugging but it would have been nicer to have a compiler pragma or error if debug is enabled?
I'll trying building a release version to test it out.

DisablePHY() gives error when compiling
Hi all, I have a small test programme from the forum to do power reduction but I can't get the Ethernet power functions to compile. If I use EnablePHY or DisablePHY in the code I get the following error when compiling. undefined reference to 'DisablePHY()' ethernet.h is included. I am using a MOD523...

Re: Lcd Code
Hi, you can run this LCD as 4 bit and you can ignore my first posting as I hadn't realised it was a text display. There is hundreds of drivers out there for these displays. They are easy to hook up to micros so you should be able to get it going quite quickly. The driver is based around the Hitach H...
