Hi,
I work with uClinux-dist-2009R1.1-RC4 on CM-BF548 module from Bluetechnix and I have problem when I enable RTS/CTS for UART in the kernel configs. The following message appears when kernel boots :
user.info kernel: Unable to attach BlackFin UART Modem Status interrupt.
Is anybody know this problem ? Has anyone heard about a patch that could fix this problem ?
Thanks in advance.
Cedric

Message: 89925 if you look at the driver you see that this error comes up when
request_irq() fails. that really only fails when the pin in question
has been reserved as something else. so check your /proc/interrupts
and /proc/gpio to make sure the pin in question hasnt already been
reserved.
