Hi,
After updating to uVision 4.53 I noticed that the debug sessions did'nt work properly with the SAM-ICE emulator from Segger: -If I set a breakpoint at line n sometimes the code execution stops at line n-1. -If I use the step-over function (F10) it does the same as the step-into funtion (F11), and I have to manually force a step-out (Ctrl+F11) on every function.
The firmware of the SAM-ICE was correctly updated after connecting it to the PC and starting a debug session with uVision. I also tried to download and update to the latest version of the Segger tools (V4.50j), wich actually replaces the DLL's provided by Keil, so if I check the system it says:
DLL version V4.50j, compiled Jun 26 2012 09:19:07 Firmware: J-Link ARM V6 compiled Jun 20 2012 19:43:26 Hardware: V6.00
Is there a patch or workaround for this issue? Maybe a specific configuration whether of uVision or Segger Tools?
Thanks.
Sebastian.
Optimization is set to Level 0 (-O0). By the way the code is compiled in Thumb Mode, using Cross-Module Optimization and MicroLIB. Using the same code and the same configuration with MDK 4.23 I had no issues while debugging with SAM-ICE.
I'll follow Mr. Bradford's recommendation and send this to Keil Tech Support.
Just to close the thread: I contacted ARM support and there was effectively a problem with J-LINK and THUMB mode (ARM works fine). A patched version of JLTAgdi.dll that solves the issue will be included in the next release.
Best regards.
