Zehn and Main Page: Difference between pages

Revision as of 09:03, 22 June 2019

Welcome to you on Hackspire, the TI-Nspire Hacking wiki. The goal of this wiki is to federate all research efforts about the Texas Instruments's TI-Nspire calculator series.

Feel free to add your contribution, the more details we get, the better software the community can create. TI Software is great for mathematics, physics, ... but independent developers are needed for all the rest, because TI does not have time for it!

Site news

June 21, 2019 - (Jim Bauwens): The Hackspire wiki is back online after a downtime of over a month due to a server failure
July 2, 2017 - (Jim Bauwens): The Hackspire wiki is 10 years old today! Many thanks to all the contributors for making Hackspire what it is today!
June 15, 2016 - (Jim Bauwens): hackspire.org is now the main domain name
March 10, 2016 - (Jim Bauwens): hosting on new server

+Welcome to you on Hackspire, the TI-Nspire Hacking wiki.
-* Full relocation (No "-fpic" or similiar needed)
+The goal of this wiki is to federate all research efforts about the Texas Instruments's TI-Nspire calculator series.
-* Every kind of section in an ELF file (E.g. ARM unwind information for C++ exceptions)
-* Executable files up to 16MB in size (can be larger if no relocations after 0xFFFFFF)
-* Various flags and extra information about the executable:
-** Maximum and minimum version and revision of ndless needed to run (https://cloud.githubusercontent.com/assets/1622084/3762493/a7ed3a22-1897-11e4-8d94-77f82ecfa239.png)
-** HW types (Clickpad/Touchpad/CX/CM) supported
-** Application name, version, author, description (these can be viewed by holding down the "catalog" key when opening the executable: https://cloud.githubusercontent.com/assets/1622084/3762440/0d70af1a-1897-11e4-860b-cf07b6521634.png)

+== Site news ==
-== Format ==
+* '''June 21, 2019 - ([[User:Jim Bauwens|Jim Bauwens]]):''' The Hackspire wiki is back online after a downtime of over a month due to a server failure
-The main header file (https://github.com/ndless-nspire/Ndless/blob/master/ndless-sdk/include/zehn.h) contains everything needed to parse a Zehn file.
+* '''July 2, 2017 - ([[User:Jim Bauwens|Jim Bauwens]]):''' The Hackspire wiki is 10 years old today! Many thanks to all the contributors for making Hackspire what it is today!
-The Zehn header (identified by ZEHN_SIGNATURE) may be everywhere (4-byte aligned) in the first 4KiB if the file starts with "PRG\0" to support backwards-compatibility.
+* '''June 15, 2016 - ([[User:Jim Bauwens|Jim Bauwens]]):''' hackspire.org is now the main domain name
+* '''March 10, 2016 - ([[User:Jim Bauwens|Jim Bauwens]]):''' hosting on new server
-== genzehn tool ==
+== Pages ==
-The "genzehn" tool (https://github.com/ndless-nspire/Ndless/blob/master/ndless-sdk/toolchain/genzehn/genzehn.cpp) converts ELF files with embedded relocation info (needs to be linked with "--emit-relocs") to relocatable Zehn files. Run "genzehn --help" to get version and usage information.
-For basic conversion it's sufficient to only specify "--input input.elf" and "--output output.tns". The resulting executable will open on every version of OS, ndless and type of hardware and the version will be 1.
-== make-prg tool ==
+<div style="overflow-x:auto">
-The "make-prg" tool (https://github.com/ndless-nspire/Ndless/blob/master/ndless-sdk/bin/make-prg) adds zehn_loader.tns at the top of the file, so that older versions of ndless without native support for Zehn. "zehn_loader.tns" is also used to boostrap ndless_resources, which is a Zehn file itself. It doesn't support any of the flags, so your executable may be executed on unsupported hardware or significantly too old OS versions! To use it, execute "make-prg <input> <output>".
+{| style="min-width: 700px; width: 100%; line-height:1.5em; border-spacing:20px 0px; margin-top: 1em;"
-It compiles zehn_loader.tns if needed.
