Dear All,
I meet a wired UART problem on linux-2.6 with MPC8241 chip. My Environment is as following: CPU: MPC8241 Linux: 2.6.12.3 COM1 offset: 0x4500, COM2 offset: 0x4600 When I booting my rootfs, it hangs at following message: RAMDISK: Compressed image found at block 0 VFS: Mounted root (ext2 filesystem) readonly. Freeing unused kernel memory: 104k init EXT2-fs warning: checktime reached, running e2fsck is recommended I had add printk in tty_write() of drivers/char/tty_io.c, the message from rootfs have printed. The conclusion is that message can be printed by printk() in linux kernel, but can't be printed by printf() in user mode. I think it must be something wrong for my UART configurations, does anybody know it?? Best Regards, Johnson Cheng -------------- next part -------------- An HTML attachment was scrubbed...
