the chip put 96k sram for both instruction and data.
It is from 0x0000_0000 -to 0x0001_8000
Set device as ARMCM3
set irom1 from 0x0000_0000 -to 0x0000_7fff
set iram1 from 0x000_8000 -to 0x0000_ffff
After compile all the code , I start debug simulation, but the code did not go to main, and the run, step are all gray, seems the cpu is in a dead loop or go to error state.
I switch back to normal option
irom1 from 0x0000_0000 -to 0x0000_7fff
iram1 from 0x200_8000 -to 0x2000_ffff
now the debug simulation is ok. The code can go to main and step is valid.
