microchipc bootloader question
PostPosted: Tue Feb 07, 2006 3:07 pm     Reply with quote
Code:


#include <16F877.h>
#fuses NOWDT,NOPROTECT,HS
#use delay(clock = 20000000)
#use rs232(baud=19200, xmit=PIN_c6,rcv=PIN_c7,errors)

#org 0x1F00, 0x1FFF void loader16F876(void) {}

void main()
{
   while (true)
   {
   printf("hello\n\r");
   delay_ms(500);
   }
}


I get an error of invalid ORG range, this code works on my older compiler. Whats the problem?

What's your compiler version? It compiles OK with PCM vs. 3.242.

Also, are you using a LVP programmer ? If not, you need to add NOLVP
to your #fuses statement.

Are you using an In Circuit Debugger like the ICD2? These device are using a small memory area at the end of RAM, this might be conflicting with your #org.
