jtango

I try to work with JTANGO break piont analyser , but I can't do it.
I have two questions about it:

- I know Iptr address must be between BPAddL and BPAddH ,
but where are BPAddL and BPAddh placed in the RAM or flash ROM.


- Defult Break trap handler address is between 401FFF30 and
401FFFF0 , but this is EMI bank 0 address in my receiver /STI5518 micro/.
What is Break trap handler address? It must be in RAM only?


My receiver has micro STI5518 ,flash ROM 2MB base add. 7FE00000-7FFFFFFF
RAM 8MB add. C0000000-C0800000.

Address 800008000 is R/W trap handler address.

If you thinking about debugging receiver firmware with JTango - it my opinion it is impossible.

you must look for address that its not used by firmware, jtango write traphandler code to memory from this address
