Nspire Color EVT到手

六合江山QQ

一个月前在X宝买的原型机。
3.0.0.1503系统。
Boot1:3.0.0
Boot2:3.0.0
没有开发机标识。
型号显示为TI-Nspire TM CX
不过，开机画面还是绿色进度条。
只能在插USB的情况下开机，我推测电池损坏。

On the back of this calculator the series number is :

May I try to install a CX OS to this EVT?

感谢去年朔雪的帖子，我没把主板连接口拆坏。
初步断定这台原型机就是去年出现过的型号，甚至更早一些。

Can not install any OS apart from which dumped from itself.

{:021:}想当个买菜计算器用，还得插着充电宝。
Can be used as a primary calculator, with external battery plug in.

内存是micron的128MB SLC+32MB LPSDR MCP，和CM上的相同，也与之前的color原型机相同。
如果没有问题，这台机子没法安装别的系统。
不过critor有提到，他的color原型机上有一个tsop封装的nor flash，厂商是MXIC，不知道你这个有没有。

扫描仪的图太小了，完全看不清……

有，在主板屏幕一面。
机身也是光滑的。
完全是去年出现过的那台一样型号。

Hi!
Nice find - thank you for the pictures and the dump.

Your 3.0.0.1503 is a development OS which was built on 8th February 2011.

The 3.0.0 Boot1 and Boot2 flashed in your TI-Nspire Color are development images: they'll only accept to run development OSes and not production OSes released on TI website.

For now, we've only dumped two other TI-Nspire CX development OSes and they are quite similar:
- 3.0.0.1045 built on 6th december 2010
- 3.0.0.DEVBUILD built on 14th february 2011

Note that the oldest one, 3.0.0.1045 is interesting as it includes an official builtin theme editor which was removed on later versions:

To install production OSes on your TI-Nspire Color, you'll either have to:

- Reflash the Boot1: this is possible as the Boot1 here is not in the proprietary ET-NS2010A-0 ASIC but on a publicly documented external Flash-NOR chip by MXIC you'll find on the other side of the board behind the J04 connector. We could achieve this on TI-Nspire ClickPad prototypes. You'll need to adapt our code for the different chip.


- Port Nlaunch CX for the 3.0.0 Boot2: You'll need to fix all syscall addresses, and other fixes are required to make Nlaunch CX run with only 32MB SDRAM instead of 64MB.

New prototype found on Taobao.

You may notice the wire attached to the top of this NS CX CAS.

Could you check your TI-Nspire Color Diagnostics version?

Diagnostics is started by holding the Esc+Menu+Minus keys while pressiong reset.

If it's version 3.00.102, you'll get a picture at the end of the "2. LCD" test, picture which has been removed on production diagnostics.
