真有趣，识别为网卡是正常现象。联机最坑爹的还是plt，使用了和84一样的vid/pid，但是协议却不一样

修改1.0.59的驱动安装信息后，驱动可以装上，具体的通信方式我再试试

我是宝贝

求购买链接~

Could you ever try the dumping method I've shared some posts ago ?

On TI-Planet, we are currently developing a way to upgrade the oldest TI-Nspire CAS+ like EVT/DVT prototypes running a 1.0.1.0.XXX Boot1 image - since such Boot1 images don't check the Boot2 signature.

But it is very important to dump your calculator first.
For historical/collector reasons, and also since we need to be able to put your calculator back in its original state in case something goes wrong.

The usual process is to dump the OS first, and then dump the Boot1, Boot2 and Diags if present.


Let's dump the OS.
First, you would need to check if your calculator is running a DHCP server.



1) get your handheld IP:
- check that the handheld is still on and connected to the computer
- type 'ipconfig' in a Windows command prompt
- you should get a local network with an IP like 172.16.xxx.xxx and a mask of 255.255.255.252
- add 1 to that IP - 172.16.xxx.(xxx+1) - this is your handheld IP

If you could find such IP, then we can go on with the easy OS dumping process.
Older prototypes, like the TI-Phoenix 1 P1-EVT1, don't start a DHCP server and thus don't get an USB IP.But yours should have an USB IP, based upon the network drivers Windows did associate to it.



2) Using the calulator keys, create a 1st level folder in your documents and name it to something easy, 'ndless' for example.



3) telnet your handheld IP on port 10002 to copy OS image to the visible filesystem
in a Windows command prompt, adapt and type :

1. telnet 172.16.xxx.xxy 10002

复制代码

you should get a 'TI_PN_' prompt

The OS image file can be in 2 different locations, /phoenix/install/phoenix.img or /phoenix/phoenix.raw
I think it's going to be /phoenix/install/phoenix.img
So type the following command to copy the OS image file to the visible filesystem :

1. fm_xfer(127.0.0.1, pn_fm_fput, "/phx/documents/ndless/phoenix.tns", "/phoenix/install/phoenix.img", 0, 0, 0) )

复制代码

A file 'phoenix' should appear in your 'ndless' folder.
It may need some time before reaching its final size - which can be up to 8MiB.

If it errors, you may try the other OS file location :

1. fm_xfer(127.0.0.1, pn_fm_fput, "/phx/documents/ndless/phoenix.tns", "/phoenix/phoenix.raw", 0, 0, 0) )

复制代码

4) get the OS image on the computer
In a Windows command prompt, adapt and type :

1. telnet 172.16.xxx.xxy 10001

复制代码

That's what TI-Nspire Computer Link 1.0 is using to transfer files.
Then, typing one of the following command should transfer the file to the computer, I don't remember :

1. fget ndless/phoenix.tns
   
2. fget /ndless/phoenix.tns
   
3. fget /documents/ndless/phoenix.tns
   
4. fget /phx/documents/ndless/phoenix.tns

复制代码

5) Share the OS image, and we'll get back to you with specific instructions for dumping the Boot1/Boot2/Diags.


If anything doesn't work, please tell us.*
Thanks.

I' sorry.Until today I didn't check my bbs massage box. This month I have many exams, so I had to review the lessons. In this summer holiday, I will try to dump the calc. If I have a result ,I will send message immediately.
