Yasdishell Assertion [SOLVED]

[frank]

When I run "yasdishell /etc/yasdi.ini", I find all 4 devices, but then it aborts with the following error message:

yasdishell: /usr/local/src/core/netpacket.c:319: TNetPacketFrag_AddHead: Assertion on '(1 == 0)' failed.

My yasdi.ini:

Driver0=yasdi_drv_serial

Device=/dev/ttyUSB0
Media=RS232
Baudrate=19200
Protocol=SunnyNet

I use Raspbian and connect via USB (PL2303) to a SMA Sunny Boy Control.

Edit: The USB-adapter works fine on a Windows PC. I also reinstalled Raspbian. The error remains.

Edit2: The protocol is the problem. YASDI works now after switching to SMANet in YASDI and the Sunny Boy Control. => YASDI does not work (well) with SunnyNet
