Hello Sergei,

yes, I did some tests with my hardware:
* read / write to flash memory
* selfmade C++ project with gcc
* UART1, some debug LEDs and CAN are working

further tests I've done:
* built the same eCos examples for the AT91SAM7X256-EK (also homebrew 
hw), running correctly
* now trying to toggle a debug LED in my tests to see something without 
the UART

As I went through the HAL's startup-code, I am quite sure that not even 
the function hal_reset_vsr() gets called. I can not set a debug LED 
inside at least.

Brg,
Bernhard
