Olimex ARM-USB-OCD and SAM7x flsh programming problems

Hello,

I’m working on a Sam7x256-ek board with a FreeRtos-based application.

I use the olimex ARM-USB-OCD to debug it and this version of yagarto tools:

  • yagarto-tools-20070303

  • yagarto-bu-2.18_gcc-4.2.2-c-c++_nl-1.16.0_gi-6.8.50_20080408

  • openocd-r657-20080516

When I program flash on my device I receive these messages from console and the LED on the olimex jtag interface start to blink green/orange:

After that I can’t start GDB.

Please, there ise someone which can help me to solve this problem ?

Thank you in advance
