This target device supports only data access breakpoints with range: size = 2^n; n = 0..31 start must be 2^n aligned Change the breakpoint definition. Select one ULINK2/ME from the Serial No drop-down list in the Target Driver Setup dialog. Unplug ULINK2/ME from the USB port and plug it back in. Cannot read ULINK2/ME Firmware serial number Communication is lost or ULINK2/ME is not working. http://www.keil.com/support/man/docs/ulink2/ulink2_errors.htm
In some cases the error may have more parameters in Ulink Cortex-m Error Cannot Access Memory format .This additional hexadecimal code are the address of the memory locations where the instruction(s) Select a lower frequency from the drop-down list. It can also be caused if your computer is recovered from a virus or adware/spyware attack or by an improper shutdown of the computer. No Cortex-m Device Found In Jtag Chain I don't know which MDK-ARM Tool Chain version you are using but maybe this could be a problem in uVision itself...

The only thing which seems to be strange is that the uLink2 is installed under Human Interface Devices with following 2 entries: *HID-compliant device *USB Human Interface Device => Reinstalling the This is required! Could Not Find An Cortex-m Device In The Jtag Chain Occurs when more ULINK2/ME adapters have been detected, but none has been selected. Keil Cannot Access Memory Stm32 Lately I'm getting a Cannot access memory error while debugging the VI.
Has it not worked since you boot up your computer this current time? have a peek at these guys Avoid Deep-Sleep modes while debugging. 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 Related Knowledgebase Articles ULINK: No ULINK Device Found ULINK: Could Not Stop Cortex-M Device Products Development Tools ARM C166 C51 C251 µVision IDE and Debugger Hardware & Collateral ULINK Debug Flash Download Failed Cortex M0

Before you start testing ULINK2, ensure that: Only one ULINK2 is connected to the PC. Breakpoints (Cortex-M) It was not possible to disable all breakpoints Occurs when breakpoints cannot be disabled while the target is running. No ULINK2/ME is selected No ULINK2/ME adapter has been selected for debugging. No Cortex M Device Found In Jtag Chain Jlink After checking I saw that memory window 1 was also initialised with 0x10000000!

Correct the address ranges and ensure they are discrete. ULINK2/ME is not connected to the USB port, or the USB driver is not installed properly, or ULINK2/ME is not working properly. This target device does not support conditional breakpoints Remove all conditional breakpoints. Reduce the number of these breakpoints.

This attempt can be made after initializing the connection, or while resetting the target, or through a stop/step command while debugging. All rights reserved.
So I am kind of out of ideas at this point, any help/suggestions would be really helpful! Reduce the number of these breakpoints.

Device is not connected, or not powered, or the debug interface is not working.
basic features: (repairs system freezing and rebooting issues , start-up customization , browser helper object management , program removal management , live updates , windows structure repair.) Recommended Solution Links: (1) Once the project is reopened the problem will go away. Execute a Power-on-Reset.
