ARM9 - Can't use Peripherals

Hi,
I'm using UV3 also UV4 with ARM7 (LPC2368/2478) with ULINK2 (Jtag). Everything works fine and I have the ability to debug the On-Board CPU.
I try to connect to LPC3250. It works (I Can program code and run) but The periperals menu is empty and I can't debug the LPC3250.

In the 'Target-Debug-Setting' the 'Jtag Device Chain' has:
0x1b900f0f - Unknown JTAG Device
0x17900f0f - ARM926EJ-S Core

Maybe the 'Unknown JTAG' is the problem - But how to solve it?

  • Doron,

    Do you have other devices on this JTAG chain -- perhaps a CPLD?

    Also -- I don't know if Keil uVision supports the LPC3250 peripherals yet... this might be coming in a future release, you could take a look at their release notes for the past several versions and see if there is any mention of the LPC3250.
