- Ok, I couldn't help it, just added 8K x 8 of ram (starting at $5000) to the
- hc11 eval board. The routine I just wrote controls a lcd display. I was
- suprised to see that I could use "load t" in this area. Now, I'm ready to load
- it to the eeprom at address $2000.
-
- I have a Superpro II device programmer. I thought it would be easy... but...
- I need the address of the routines to start at $2000 so the mpu can actuate it
- accordingly. I compiled the code using an "org" of $0000, but the as11
- compiler used the "local" branches and jumps instead of the extended ones.
- Needless to say, this really messed up the addressing to the eeprom.
-
- Superpro has the ability to address offset. Ok, but the starting address is
- higher than the last address of the chip. So if I compile it at org $2000, it
- doesn't load into the buffer to be loaded to the eeprom.
-
- I must be missing something... How is this done??
-
- Thanks,
- Eric.
