Cedric Marin (FRANCE)
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.
