MCU

The MCU of the Nokia is based on ARM architecture. Most of the code uses Thumb instructions. For those interested in ARM specifications the site www.arm.com has detailed information.

Memory map

Section Start addr End addr
I/O (??) 0x20000 ??
RAM 0x100000 0x10FFFF
Flash 0x200000 0x2FFFFF

I saw other addresses accessed, but I don't know what they are, so I didn't include them here. Maybe someone reading this pages can help me with this.

Flash zones
Section Start addr End addr
MCU 0x200000 0x2AFFFF
PPM 0x2B0000 0x2FFFFF

The MCU is the main program of the phone. The PPM (Post Programming Memory - if I'm not wrong) contains the text in different languages, the ring tones, the fonts and other info that I'm not very sure what it is.
