Hi, I am working on an 8260 based board and currently cannot get the serial (running on SMC 1) to work using the 2.6.11 kernel. The last message I see in my console is: "Now booting the kernel".
I currently use NFS root for mounting the root filesystem. Despite not seeing any output from the serial console, the board does actually boot up and I can telnet in okay. Here is what I see in: /proc/interrupts: CPU0 4: 0 CPM2 SIU Edge cpm_uart 32: 23184 CPM2 SIU Edge fenet BAD: 793 /proc/devices: Character devices: 1 mem 2 pty 3 ttyp 4 /dev/vc/0 4 tty 5 /dev/tty 5 /dev/console 5 /dev/ptmx 7 vcs 10 misc 13 input 128 ptm 136 pts 204 ttyCPM 254 devfs Block devices: There are no block devices installed. In /dev, I see: crw--w--w- 1 root root 204, 46 Jan 1 00:32 ttyCPM0 And when I do "dmesg", I see: ... ... Serial: CPM driver $Revision: 0.01 $ ttyCPM0 at MMIO 0xf0011a80 (irq = 4) is a CPM UART ... ... I currently do not specify the "console=ttyCPM" in my boot command line. Would this be an issue? I have tried to add "console=ttyCPM" to my boot command line but in such cases, the kernel would fail to boot. Using some LEDs as debug, I tracked down the hang which seems to happen during cpm_uart_console_write. This is as far as I got. I am running with devfs enabled in the kernel. Does the cpm_uart driver work with devfs? As an aside, I have ported the 2.6.5 kernel to my 8260 based board and both ethernet (FCC 1) and serial (SMC 1) worked okay using this particular kernel. Any suggestions/ideas would be much appreciated. Thanks, Chi
