[microblaze-uclinux] Why does open("/dev/ttyS0",...) fail in my user app?

[Brettschneider Falk <fbrettschneider@xxxxxxxxxxxxxxxxx>]

Hi,

Following the hint of John Williams I think now I prevent the blocking of
the serial port by the ucLinux console as I commented out the code lines in
function "void xmbrs_console_init(void)" of file
uclinux_dist/linux_2.4.x/arch/microblaze/kernel/xmbserial.c and recompiled
the kernel.

But anyway, this posix code in my user app still fails with return value 0.
	int fd = open("/dev/ttyS0", O_RDWR | O_ASYNC, 0666);

Any idea?

Mit freundlichen Grüßen / Best regards
