Quote:"calculation" code is in amrif.elf(inside u can see references to SDKLIB.DLL and CORE.DLL, sounds unbelievable but it's real ELF, which use DLL libs). Also this code have some opensource libs for math.

So far, you've discovered nothing that we didn't already know (and is documented on the TI-Planet hpwiki, or is common knowledge, such as HP using some version of xcas).

But be sure to go on: it's pretty good to see someone else interested, and who has some time on his hands

As already outlined elsewhere, the first step towards Linux would be to replace armfir.elf with another ELF file, loaded at the same address (we know that it works), and drawing something onto the screen until the calculator is unplugged from a USB host and a battery is removed.

Ups I didn't see. What about hardware? How start bootloader?
