i am a new user of upsd333d.

I want to write an IAP program which located in the 2nd flash to changing the application program in the 1st flash, and i still have some questions:

psdsoft mapping:

2nd flash : code

1st flash : data

fs0: 0-1fff or page0 8000-ffff

fs1-fs7: 8000-ffff

csboot0: 0-1fff or page0 8000-9fff

csboot1: page0 a000-bfff

csboot2: page0 c000-dfff

csboot3: page0 e000-ffff.

but i do not know how to change fs0 from 0-1fff(program) to 8000-ffff(data)?

after changing vm, how can i control pc=0x0000 without restart, because my interrupt sector from 0x0000.

thanks!!
