Parameter -ADARM missing.

Is /dev/ttyUSB0 assigned to the used COM-Port/USB-UART-converter by the 
system?

The crystal is 32kHz (k not M), the PLL will generate the core-clock 
(ca. 45MHz IRC). If remembered correctly the frequency is not needed by 
the ADuC702x-bootloader.

Also try with lower "baudrates" during tests (start with 9600). Use 
-debug parameter to get verbose outputs.

From the ADUC7026 manual: "The ADuC702x will enter serial download mode 
after a reset or power cycle if the BM pin is pulled low through an 
external 1kOhm resistor." On Olimex P7026 BM is connected to button SD. 
Just read the schematic and the manual.

If there are still problems try with the download-utility from Analog 
Devices on a MS Windows system to check if hardware and connections are 
o.k.

The lpc21isp yahoo-group might be a better place to ask.

Thank you for your time...

1)yes the board is ADuC-P7026

2)Parameters -ADARM was trying but it also doing nothing

3)I dont properly understand
Is /dev/ttyUSB0 assigned to the used COM-Port/USB-UART-converter by the
system?
I you mean if the board should be on ttyUSB0 than yes I typed the
-ls /dev/ttyUSB* and it is showing me USB0.

4)and was as well trying lower baudrate but also no luck

5)And as you said to look into manual this is the problem the olimex 
does not present any manuals to this board only schematics and examples 
but no such a ting like how I should use the buttons and all..


any other idea?  :-) Thank you
