I use keil and ulink tool, I want to test the LPC2468 code on EA LPC2468 OEM board, after the project is compiled correctly, I click the load button in keil, the screen display a message box, the content:"Cloud not stop ARM device! please check the JTAG cable".I am really sure that the ULink is ok, because I can use it debug the keil 2140 board. I check the jump on board. the Enable JTAG is closed, so it is correct. I don't know what is the reason. do i need change the ULINK to ULINK2?
anyone has any ideals? Thanks in advance.
Download the latest Eval Version MDK3.05 (www.keil.com/.../arm.htm).
For ULINK1 you need to reduce the JTAG Clock to 100KHz.
For ULINK2 you need to select RTCK as JTAG Clock (which uses the return clock of the device).
The setting is done under Project - Options - Debug - ULINK Settings.
