For example, on the CPU86 board you include this code: ... #elif defined(CONFIG_CPU86) #define CONFIG_SERIAL_CONSOLE_PORT 2 #else ... which maps to SCC2. Do you really have your console port on SCC2? I think it is generally a BAD idea to copy some board-specific code without checking CAREFULLY what you're doing. You tried, and you got what you deserved: a non-working system ;-) Best regards, Wolfgang Denk -- Software Engineering: Embedded and Realtime Systems, Embedded Linux Phone: (+49)-8142-4596-87 Fax: (+49)-8142-4596-88 Email: wd at denx.de Weekends were made for programming. - Karl Lehenbauer ** Sent via the linuxppc-embedded mail list.

You don't need any patches when using our kernel; it has been tested with up to 6 x serial ports (2 x SMC, 4 x SCC, for example on MicroSys CR826/PM826 boards).

MPC8260 serial on SCC support
Hi, Is there support for serial console on SCC for MPC8260 in latest kernel distributions included in the ELDK or kernel version on the ftp://ftp.denx.de? I am using custom MPC8260 board that has serial on SCC. Also I am using ELDK with the kernel version linux-2.4.4-2002-08-09. I cannot find the SCC serial support. I also saw posts with the patches for serial on SCC for MPC8260 and downloaded the patch but could not patch the kernel sucesfully. Is there some other patch for this or how can I include support for this in my kernel? Thanks in advance. Dejan Jovanovic ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
