My fault. sorry :( Really no problem! I rather try broken stuff than nothing at all. So also wrong tries are greatly appreciated! And besides... also failures serve a purpose: You learn how not to do it ;) > This should have been: > s3c2410_gpio_cfgpin(S3C2410_GPF1, S3C2410_GPF1_EINT1); OK, here we go: It does not "crash" anymore but it also does not help either. The interesting thing is that supposedly also during run-time the interrupt handler should at least printk() that the wake-up int has occurred, which should assumingly happen when calling the NEO. But even at run-time exactly nothing happens. That leads to two assumptions: 1. The modem still needs to be configured to assert the modem wakeup signal - How? 2. The wakeup irq GPIO is still wired incorrectly? I think at this point we need help from someone who knows more about the modem or the wiring... > Arnaud Cheers nils faerber -- kernel concepts GbR Tel: +49-271-771091-12 Sieghuetter Hauptweg 48 Fax: +49-271-771091-19 D-57072 Siegen Mob: +49-176-21024535 --
