Platform: Mac OS X 10.9 Eclipse: Luna These are my plugin versions: GNU ARM C/C++ Cross Compiler GNU ARM C/C++ Documentation (Placeholder) GNU ARM C/C++ Generic Cortex-M Project Template http://developer.mbed.org/teams/ST/wiki/Nucleo-Firmware And use the latest version of StLink Utility. Lower the Max Clock frequency in the ULINK USB-JTAG/SWD Adapter section. I've attached the debugger log. http://www.keil.com/forum/17744/cannot-access-memory-error-on-mcb1700-amp-example-project

Keil Cannot Access Memory Stm32

I compared my project with Blinky and found out that in my project I didn't enable "Embedded Flash Configuration" in STM32_Init.c! Preferably, copy-paste the error message.

So I check the system_stm32f4xx.c and find out the default clock setting isn't 84Mhz,then I changed PLL_M=4 PLL_N=168 PLL_P=4. However when I tried the same board with an external ST-link dongle it worked.

After enabling everything works fine! Brought to you by: ilg-ul, justxi Summary Files Reviews Support Tickets ▾ Bugs Feature requests Support requests Beta versions News Discussion Git ▾ Second Edition Experiments Files ReadMe QEMU QEMU Tests But another problem is, and was, that the Keil compiler halts the execution of the program (no breakpoints are set) and I have manually make it run again. http://www.keil.com/support/man/docs/ulink2/ulink2_errors.htm I can compile it there, and download it to the board with ST-Link and it runs.

In some cases, the target's debug block not functioning properly raises this error. I think I will send my uLink2 back to Keil! Download the program to Flash. Will see if I have a 401 Nucleo to hand...Share PostEdited: 12/26/2014 7:08 PMView Properties/AttachmentsReplymajerle.tilen Posts : 101Frequency matches, like I said, it works with external debugger (F429-Disco and ULINK2).Also,

Keil Cannot Access Memory Stm32 Read-Only AuthorJohn Linq Posted19-Oct-2010 01:48 GMT ToolsetARM RE: Cannot access memory error on MCB1700 & example project John Linq Hi Côme MAESTRACCI, I think you are using Keil MDK v3.50 and Ulink - Cortex-m Error Cannot Access Memory Flashing Cannot Load Flash Device Description Flash description cannot be loaded from the built algorithm (corrupted).

After deactivating or changing it to 0x8000000 it seemed to work because there were no Error messages left! get redirected here Select the SW port in the ULINK USB-JTAG/SWD Adapter section of the Target Driver Setup - Debug dialog. As a side effect of this behavior the connection dialog often is not closed. but after read all the discussions on this page,I realized maybe it's the swv clock setting didn't match the trace setting as Clive1 mentioned.

Once you have the board, connect it to your board and use the Debug Port Unlock utility on the Other Utilities tab of LMFlash. navigate to this website The edit button didn't seem to work so I changed the .cproject file directly:

This target device only supports two data access breakpoints Too many data access breakpoints have been defined.

Avoid accessing invalid memory areas on the target system. The message is raised when the target's Flash was not programmed with the code being debugged. Cannot read ULINK2/ME Firmware serial number Communication is lost or ULINK2/ME is not working. I assume this supports SWD?

This target device does not support any other breakpoints when: — one complex range breakpoint is defined. — two simple range breakpoints are defined. — two data access breakpoints are defined.
