| Nover 2.1 |
+-----------+
by Critor
http://tiplanet.org
1) Introduction:
------------
Nover is a program to downclock / overclock your TI-Nspire.
2) WARNING:
-------
NOTE THAT THIS PROGRAM IS DANGEROUS AND HAS THE POTENTIAL TO PERMANENTLY BRICK YOUR CALCULATOR.
ACCORDING TO THE LICENCE, USING THIS PROGRAM DOES VOID YOUR CALCULATOR WARRANTY.
Use it wisely.
3) What you need:
-------------
- You need a TI-Nspire, TI-Nspire CAS, TI-Nspire TouchPad, TI-Nspire CAS TouchPad, TI-Nspire CX or TI-Nspire CX CAS calculator.
- You need to install Ndless 3 on it or a compatible kernel.
4) Installation:
------------
Send Nover.tns to /ndless/startup/
//注：实际上这一步是让nover开机自动启动，实际使用过程中任意目录均可。建议先运行一次看看会不会重启，否则.......
5) How to use:
----------
On the nover screen you can modify 3 parameters in the following order:
- base frequency (direct setting)
- cpu frequency (set through the base frequency divider)
- ahb frequency (set through the cpu frequency divider)
6) Controls:
--------
Left/right arrow or +/- to increase/decrease a parameter value.
Up/down arrow to switch to another parameter.
Enter to set the new configuration.
Var to store current configuration to a file.
Shift to load configuration from a file.
Esc to go back to the OS.
7) The maximal values:
------------------
On a TI-Nspire or TI-Nspire TouchPad, you should be able to increase those parameters as much as you want.
On a TI-Nspire CX, the maximal cpu frequency is usually something between 220 and 240MHz.
A "warning" is displayed to tell you that you're near/over the limit.
A too high value should just freeze/reboot your system.
On a TI-Nspire CX, be very carefull with the AHB frequency.
A "warning" is displayed to tell you you should immediatly STOP increasing the value and go back to a safe value.
A too high value generates random read/write failures in the NAND ROM chip and can corrupt it permanently.
To determine the maximal values on a TI-Nspire CX, you should:
- start with a stable config:
* increase cpu to the maximum
* decrease base until the warning on the cpu disappears
* decrease ahb until its warning disappears
* press var to store this stable config
- look for a better stable config:
* increase base value by one step (ignore the cpu warning - it's not dangerous and will just reboot if it is too high)
* if a warning is shown for the ahb, immediately decrease it by one step
* set this config by pressing enter
* exit the program by pressing esc
* try to use your TI-Nspire CX normally
* if there are no problems
-> restart Nover press VAR to store the configuration
-> retry to increase base value...
8) Recovering from a permament boot "System error":
-----------------------------------------------
//遇到开机进不去系统的看这个
You set a too high AHB value on your CX and are now stuck with a permanent system boot error?
Access the maintenance menu:
- Use a pin to press the reset button on the back and keep it pressed.
- Press and hold the 3 following keys: Home Enter EE
//注：此处有误，应该是Doc+Enter+EE 同时捅reset， CX-C的Doc为“文档”键
- Release the reset button but keep holding the 3 previous keys.
When the loading bar reaches 50% you should get a menu.
//实际上就是恢复模式
Use option 4 to completly reformat the NAND ROM.
You'll then have to reinstall an OS.
If you still get the "system error", access the maintenance menu again and use option 2 to remove the OS.
If you still get the "system error", access the maintenance menu again and try to use all 2-3-4 option in a various order and several times.
9) Licence:
--------
GPLv2. Source code is included.
You may modify the source code according to the included licence and my copyright.
//源代码就不发了，需要的可以和我联系
10) Release history:
----------------
09.04.2012: 2.1 - can now save/load config to file, and be automatically started by Ndless at boot time
19.01.2011: 2.0 - added CX support
08.01.2011: 1.1 - added touchpad & OS 2.1 support
28.12.2010: 1.0 - initial public release
