Hi,
I have a problem with an Enery Micro µC EFM32G200F64 and uVision V4.14.4.0: 1st error: SWD communication failure 2nd error: Error: Flash Download failed - ... I have tested the following: - The ulink2 works fine with an other harware via JTAG. - The target hardware with the EFM32G200F64 works fine with an other link device and an other development system too. The ulink2 doesn't work with the EFM32G200F64 target hardware. It is a standard 20 pin JTAG connector used on the target hardware and the ulink2 also. I have tested several settings in the project options - debug - ulink cortex debugger - settings menu, but nothing help: Debug: - ulink serial number is shown - SWJ not marked Port: SW - Max. Clock 1MHz - Connect: Under reset - Reset: Autodetect - Reset after connect is marked Trace: - off Flash Download: - Erase full chip - Program, Verify, Reset and run all marked - Ram for Algorithm: 0x20000000 0x0800 - Programming algorithm: EFM32G / on chip flash / 128k ...
Can anybody help?

I've solved the problem. It is necessary to make a power cycle after each change in the settings. My actual settings are:
-> project - options - debug - ulink cortex debugger - settings menu: Debug: - ulink serial number is shown - SWJ not marked Port: SW - Max. Clock 1MHz - Connect: normal - Reset: Autodetect - Reset after connect is marked - Cache Options both marked - Download Options both not marked Trace: - off Flash Download: - Erase Sectors - Program, Verify, Reset and run all marked - Ram for Algorithm: 0x20000000 0x0800 - Programming algorithm: EFM32G / on chip flash / 128k ...
