Hi,everyone.
That's very starnge that UART1 works well but
UART2 didn't work at all...I added the similar
code in the kernel.And also see both of them in
the booting information:
/dev/ttyS2 at MMIO .....(I checked, it's right.)
The problem is I couldn't see the wave in the
hardware pin D2,D3 in UART2 so I couldn't receive
any data.
I tried to exchange the irq between UART1 and
UART2,then both of them didn't work..Maybe the irq
of UART2 has something wrong?
Maybe this is caused by the "Autoflow Control"
of UART2 seems UART1 doesn't have it?
My case in arch/arm/mach-davinc/clock.c is
case DAVINCI_LPSC_UART2:
PINUMUX1 |= 0x4;
Anyone else had enabled the UART2??Could you
kindful to show me the mistake of mine??
Thanks a lot...
