Hi Wolfram
Thanks for your reply.

Ups, forgot to attach.
The bootlog is below. There is no output or error msg of the kernel.
Its just gone: no network no nothing. There is a jtag interface but
i haven't figured out how to use that.
There is only one pcf8574 connected to the i2c bus and nothing else, so
i think that dumping the i2c bus should do no harm?
Best regards
ST
