No programming to Board

我正使用 mini2440 时遇到问题.

A: 并口连接>
1. 打开 H-JTAG 可以找到 ARM920T 0x0032409D
2. 打开 H-Flasher, Load H-Flasher_mini2440.hfc
3. 到 Programming, Check
4. 有以下错误. Error: Can′t halt target and make it enter DEBUG state, for USB H-JAG, please reduce the TCK speed and try again.
5. 试图 Load H-Flasher_SST39VF1601.hfc, 然后 Check. 得到同样错误.

B: USB 连接
1. 用 SEGGER J-FLASH
2. Open Project mini2440.jflash
3. 试图 Connect
4. 得到错误 Unable to halt ARM core Failed to connect.


目前无法使用开发板. 如何解决?

动作要快一些，可以在手册中搜"快"查找相关说明

I solved the problem so far.

The board is switched to start at NAND, in order to avoid the wrong programming in NOR. Then I can stop the ARM core and erase NOR and so on.

I just wandering that in this case ARM core runs dead and JTAG command can not stop it.
