Perhaps just brain fade but can someone double check me on this. I am using Keil on an 8052. I have a function pointer saved in a xdata structure. While I see the 3-byte pointer being saved, when I try to use the function the compiler goes to 0x000.


The pointer is saved like this:

pLongTrimSwitch->process = tr_process;

I can confirm the address of tr_process() is saved inside the xdata struct 'network.process' which pLongTrimSwitch was pointing to.

But when I call:

(*network.process)((unsigned int*)network.ca.cdata);

I get a lcall to 0x0000??
