Hi. I wrote my own console driver based on the ARC console driver (to keep it simple). When I am booting my modified 2.4.3 kernel, I get an "unable to open initial console" error (code: No such device). I have tracked it down to the point where the kernel searches for a valid TTY device with major and minor ID 4:64. All devices that are present at this time are: 3:0-3:256 2:0-2:256 5:0 5:1. Obviously there is no 4:64 device. I mount root via NFS and my devices are as follows:. crw------- 1 root tty 5, 1 Mär 4 17:49 console crw------- 1 root tty 4, 0 Mär 4 17:49 tty0 crw-rw-rw- 1 root tty 4, 1 Mär 4 17:49 tty1 ... crw-r--r-- 1 root root 4, 64 Mär 5 08:26 ttyS0 crw-r--r-- 1 root root 4, 65 Mär 5 08:26 ttyS1 I also add a "console=ttyS0,9600" to the kernel command line. Am I missing anything? Why is there no device 4:64? (My console driver identifies itself as 4,64) Any help would be appreciated. best regards -- Andre Messerschmidt Application Engineer Infineon Technologies AG
