XDS100 on AM335x SK is very slow for big Applications

Hi everyone,

Im using XDS100 emulator on the AM335x Sk board. When the application is small the spped of the emulator was fine(but still much slower than Jlink/ST-link which I have used before). But as my application grew in size the emulator became slower and slower. Now it often cashes somtimes when I start to debug and I get the following error message.

FYI : I use IAR embedded workbench

Fri May 09, 2014 12:58:47: Fatal error: Failed to connect to the XDS100/200 emulator (connect CPU)... (Error -2062 @ 0x1FE) Unable to halt device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.114.0) Session aborted!

After I reset the board, I can start the debugger but cannot stop it. The debugger crashes again. I get the following error

Fatal error: (Error -2062 @ 0x1FE) Unable to halt device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.114.0)

How can I get rid of these errors and speed up the debugger? Any help would be much appreciated. Thnx.
