Bug#495351: [Ecls-list] ECL sigill on debian armel (lenny)

[Detlef Schmicker]

Hi,

as there is no simple well documented way to install a standard
armel-omap kernel on the N800 (at least I could not find one) I have
problems to install a more recent kernel than 2.6.21-omap1 (with maemo
patches), which is the most recent kernel nokia offers at the moment. I
will test as soon as I have a more recent kernel availible on N800. As
another difference between working debian and not working debian is the
processor / gcc

Processor	: ARMv6-compatible processor rev 2 (v6l)

it might still be a processor problem, but as I understood it should be
backward compatible. Does anyone have ecl with an ARMv6 running?
