Hi thanks a lot for the info.
One question regarding the TTL to USB device, should I get one using3.3V or 5V signals ? I see both model exist ...
Thanks
You should use 3.3V.

Method 1:
First turn off the scope and connect the scope to your computer.
Press F1 and power button ...
Both solutions are not working.
As soon as it get some power from USB or battery the scope is starting.
I can see the DFU mode in windows device manager but it stay less than a second and the scope is automaticaly booting.
Any other idea?
Why do you need an oscilloscope, if you can not program the CPU ?

Hello,
I've tried to follow the procedure described in "Program Arm1" but the Flash Loader demonstrator keeps on saying that there is no response from the target (I see a brief led flashing on the USB to TTL board).
I've checked that I've installed the proper drivers for the USB to serial device and this part seems to be working ok (device is detected, USB port is created).
I did put a jumper between the 2 pins as described and then I plug in the USB cable in the computer.
the Flash loader states "Verify the boot mode configuration" and the flash protection status (see screenshot); I've only set the jumper, is there anything else to do on the scope (hit a combination of keys to start it in the proper mode ? I've tried power+F1 with no success).
Thanks for any advice ... I'm quite stuck here :(

Connect RX to TX and connect TX to RX
Thanks for the hint (I should have thought of that ...) unfortunately it did not solve my problem. Still the same error from the software (I still have a led flashing briefly on the USB to TTL device and that's it).
Any other hint I could try ?
