计算器程序
程序名称: Nover
平台: TI-Nspire 
系统/软件要求: OS3.1 & ndless 3 >=r611 (2012年4月之后版本)
版本号: 2.1
类型: 其他 
作者: Critor
大小(K): 243
更新日期: 2012-04-09
描述: Nspire 超频工具,All series 适用
已知缺陷: 风险大,容易造成数据丢失(尤其是CX,Classic Nspire好像没有多大问题)
源代码: 闭源
/*
先说一点废话
其实这个程序我在刚刚发布那会就拿到了
不过一直没有时间进行详细的测试
而且,测试期间经历了3次OS丢失,2次Format(丢失一切数据)
不过,还是把基本的用法找出来了

先把原来的说明文档贴出来吧:
+-----------+
| 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

11) Thanks to:
    ---------
The TI-Planet community for their encouragements. (   http://tiplanet.org   )

下面说说我发现的比较安全的用法(for CX)
CX和Classsic Nspire 相比复杂很多
默认CX是运行在这个状态的:

Boot Loader Stage 2 (3.10.16)I_OS_INSTALL_VERIFYING_IMAGE
Build: 2011/7/6, 14:38:40                        
Copyright (c) 2006-2010 Texas Instruments Incorporated incremental update (57)                              
Using production keys
TI_OS_INSTALL_VERIF
Clocks:  CPU = 132MHz   AHB = 66MHz   APB = 33MHz                                    
TI_OS_INSTAL
Checking for NAND: NAND Flash ID: Generic 1 GBit (0xA1)   

(用USB2TTl,连接RS232输出看的,这个是启动过程中BOOT2的信息)
切记:不要让AHB显示dangerous!否则重启是必然的。
如果超频失败设备会自动重启,当然有时候会有特殊情况需要自己捅reset

初始以系统默认频率为例,其他情况请自调整

首先进入界面,可以看到有3个进度条,分别代表Base frequency,CPU frequency,AHB frequency
然后,上下是切换进度条(可以明显看出哪个进度条有焦点)
左右就是调节频率了
如果想小小的超一下调节Base frequency就可以了
不过事先请切换AHB,然后按一下左(降低AHB频率,防止重启导致超频失败,重启有时候会造成数据丢失)
然后再回到Base,按右不断增大就可以了,可以看到,AHB和CPU随Base的值进行变化
这样最大可以开到 CPU 189 AHB 63 Base 378
然后按enter就可以生效了。
这个时候相对稳定,同时可以发现,速度有一定改善,比如说进入“我的文档”载入时间变短

还有一种是调CPU的

先切换到CPU,按一下右,此时会发出Dangerous的警告,不用理会
然后调整AHB直到AHB不报警
接下来,调整Base,减小至240以下(此时CPU频率和Base相同)
246及以上必然失败
同时,虽然在240时AHB可以到80,不过,非常不稳定(xpi_lua测试未通过)

此外,每次调整时可以按var保存当前设置,若重启可以按shift直接载入然后进行进一步微调。
