Hi, In my project, I have defined two io memory ressources as devices. I want connect these two devices to vbus. "io_bus.gpt2" is actually connected to vbus. But is it possible to also connect "io_bus.intc" to vbus ? local name = "l4rtos"; local DeviceFile = "beagle.devs" local IOFile = "beagle.io" local loader = L4.default_loader; local io_bus = { gpt2 = loader:new_channel(); intc = loader:new_channel(); }; loader:start({ caps = { gpt2 = io_bus.gpt2:svr(), intc = io_bus.intc:svr(), icu = L4.Env.icu, sigma0 = L4.cast(L4.Proto.Factory, L4.Env.sigma0):create(L4.Proto.Sigma0), }, }, "rom/io rom/" .. DeviceFile .. " rom/" .. IOFile); loader:start( { caps = { vbus = io_bus.gpt2, icu = L4.Env.icu, log = L4.Env.log:m("rws"), }, }, "rom/" .. name); Regards, Pierre Larus
