Hi Pascal, very interesting - with owhttpd or owfs connected directly to the busmaster I can access the BAE 910 chip and all its registers and even change the content of a user register (at least via owhttpd) - without any crash.
Further when I access a property with the "cat" command and with owfs connected to owserver I can also read and write a register - and no crash. But as soon I use any "dir" functions they crash So it seems to be a problem with the "dir" function when owhttpd and owfs are running as clients.
