[ECOS] Re: STM32 ROM .bin does not start

[Bernhard Gebert]

Now the problem is solved.
The following extracts are working corectly.

Thank you, Sergei. From now on I'll use arm-none-eabi-objdump more often!

I feel not fit enough to create a new CDL variant for the STM32 
single-chip so I am not able to contribute this to the repository, maybe 
later.

Brg,
Bernhard
