Re: [Bluez-users] bt3c_cs time out - no firmware loaded?

Hi Ben,
Hrm... The problem isn't simple. You are just not supposed to tap IOs
that way from userland, especially since PPC arch doesn't have anything
like "PIO" instructions. The IO space of your card is actually mapped
somewhere in physical memory, that "somewhere" not beeing generally
available to userland.

Can you tell me more about the card ? Is it a 16 bits PCMCIA device or
is it a cardbus (PCI) one ? Why can't you tap the IOs solely from within
a kernel driver ?
this is a 16 Bit PCMCIA card. We need to load the firmware from
userspace, because we can't distribute it within the kernel driver due
the legal issues. At the moment we don't even distribute the firmware
file with our userspace firmware loader program.

Regards

Marcel
