Posted by Dexter on June 5, 2003, 10:33:10, in reply to "how to run both the kernel and my appl in RAM for debugging?" As for HMON reflashing your chip you are correct here. The 100 write/erase are guaranteed at full temp range, in practise it is many many more, I have used an EDK for millions of re-writes at room temp. I am sure you will not have a problem. Shadow vectors. As you know when an interrupt occurs the CPU branches to an address stored in the vector table. For a monitor it is handy to keep the address of the vector the same, this way the vector table doesnt change. Instead each vector points to a shadow table in RAM. Then then shadow table can redirect the CPU to the correct address, it does this by adding a H'5A000000 to the address, this then makes a JMP instruction to the new location. Changing the address of the ISR only changes the RAM contents not flash.

I have not used the tutorial that you are mentioning so I can not comment on this. If you tell me more maybe I can help.
