Hi there, I am trying to use ELDK 4.0 on my TQM860L board.
I have compiled the included 2.6.15 kernel with reasonable options, but when I try to boot it, I do not get the prompt after the message "Uncompressing Kernel Image ... OK" Actually, I know that the system is not hanging because 1) I see there is network traffic between the board and the NFS server 2) There are messages written in /var/log/messages, and I see that the initialization is completed (even my /etc/rc.local has been executed) So I suspect that the problem comes from reading/writing on the console. As my /etc/inittab has the line ............................................... 3:2345:respawn:/sbin/mingetty --noclear console ............................................... I have put a wrapper around the binary "mingetty" and I have checked that indeed it is called... only that I do not see anything on the screen. I am pretty sure that this problem is related to the kernel because if I boot on a 2.4 kernel with the same root filesystem everything works fine. With the 2.4 kernel I had the following messages in /var/log/messages ................................................................. Jan 22 12:16:34 tqm kernel: ttyS0 at 0x0280 is on SMC1 using BRG1 Jan 22 12:16:34 tqm kernel: ttyS1 at 0x0380 is on SMC2 using BRG2 ................................................................. and with the 2.6 ......................................................................

I have tried to create these devices with the following characteristics: ...................................................................... crw-rw---- 1 root root 204, 46 mai 3 14:43 dev/ttyCPM0 crw-rw---- 1 root root 204, 47 mai 3 14:43 dev/ttyCPM1 ...................................................................... but to no avail. I have seen that there are many new options related to serial lines in the new kernel, so I guess that I am doing something wrong. Thanks in advance for any hint.
