If the JTAG Device ( or SW Device) list box contains an ARM Device Name and IDCODE, continue with the next step. Before you start testing ULINK2, ensure that: Only one ULINK2 is connected to the PC. Check if the target is powered. Thanks! have a peek here

This attempt can be made after initializing the connection, or while resetting the target, or through a stop/step command while debugging. To rectify just open the Memory window 2 and clear the address filed (and close the memory window 2) and close the project so that the settings are saved. http://www.keil.com/support/man/docs/ulink2/ulink2_errors.htm
Could Not Find An Cortex-m Device In The Jtag Chain
As a side effect of this behavior the connection dialog often is not closed. This is a warning (not an error), which occurs when no Flash algorithm has been found for a certain address range. Firmware is corrupted or cannot be downloaded due to hardware problems.
So my question is if the ulink2 or the mcbstm32 causes the problem? I have tried to connect with all posibilities (JTAG, SW, different connect & reset options) but everytime I get the same error! Additionally debugging this or all other projects worked fine in the past, so I don't think this can be the failure! No Cortex-m Device Found In Jtag Chain ULINK2 is not connected to the target system.
It is the example project within KEIL v3.50, or it is the example project from NXP? Cannot Access Target Shutting Down Debug Session Execute a Power-on-Reset. Too Many JTAG Devices in Chain Either too many JTAG devices have been detected in the chain (maximum 64 devices are allowed), or the JTAG communication is corrupted and it behaves his comment is here Zero Device Size Occurs when the device size is defined as 0 in the Flash algorithm.

Preferably, copy-paste the error message.
Reduce the number of these breakpoints.
The following breakpoint combinations are supported: When executing from volatile (RAM) memory: unlimited address breakpoints and one data access breakpoint two data access breakpoints When executing from non-volatile memory, for example

Enable the SWJ switch in the ULINK USB-JTAG/SWD Adapter section of the Target Driver Setup - Debug dialog.

Missing Flash Algorithms. Is it the uLink2 correct installed under Human Interface Devices with following 2 entries: *HID-compliant device *USB Human Interface Device ?? Macro Sequence Error Internal driver error. No Cortex M Device Found In Jtag Chain Jlink Breakpoints (Cortex-M) It was not possible to disable all breakpoints Occurs when breakpoints cannot be disabled while the target is running.
Target not connected or not powered, or JTAG interface is not working. Occurs when more Flash algorithm are defined for an address range. There is now address displayed together with the error! Avoid accessing invalid memory areas on the target system.
