<tt>Oh I see Vadim, I guess that code is running but I cannot see
that it is!<br>
As soon as it runs, it needs non standard speed and I'm screwed
with my cable!<br>
<br>
But do you know if some firmware (Hello world?) doesn't make use
of non-standard speed...<br>
If this is the case, I still don't understand why I don't see that
the code is running with such a firmware</tt><br>
<br>
<tt>btw i cannot make a decent cable with my FTDI cable - Tx is at
9V level! I'll burn my calypso chip.<br>
I bought a CP2102 USB to UART converter at 3.3V level.<br>

<div>non standard high speed setup after layer 1 is already loaded

can not communicate with it cause PL2303 not support non

Hello Harald and Lukas,<br>
<br>
In my opinion regarding non-standard speed, PL2303 based
cable should<br>
never succeed to load code into calypso ram...<br>
The wiki says that for some branch and/or firmwares it
works, I don't<br>
understand how it can happen.<br>
<br>
btw with my pl2303 cable what branch / firmware do i have to
use for<br>
loading a GSM layer1 into my C123... with succeed?<br>
<br>
Ps. I bought a RS232 / Jack adaptator. I wait for it... (I
already have<br>
a FTDI RS232 / USB cable) - If i have a little time I can
braze a jack<br>
on the RS232 as explained on the wiki<br>
<br>
Sorry for my late answer and thank you both for your help.<br>
I didn't had time to work on my problem :(<br>
(right now I have trouble with my soft raid 10 in dual boot
who drives<br>
me crazy!)<br>
