Overview
On the leaked versions of the updates files, the 'firmware.zip' archive contained :
- the Operating System (v0.26, v0.30)
- the Boot Code (v11+)
- an USB tool to install the above versions (having an interface letting you read/write images from/to any memory address - which is clearly not the final interface)
The several files for the calculator side are : APPSDISK.DAT, armfir.elf, BESTAARM.ROM, BXCBOOT0.BIN, MASTER.DAT.
Analysis
APPSDISK.DAT
A 32MB disk image, contains a FAT16 partition at offset 8K.
armfir.elf
ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, stripped. There's a copy in APPSDISK.DAT/programs/misc/.
BESTAARM.ROM
Seems to be part of the bootloader.
BXCBOOT0.BIN
Seems to be part of the bootloader.
