the Blackfin Linux UART driver already takes care of all DMA/PIO transmissions.  use it like any other serial device from userspace and dont worry about managing kernel issues like interrupts or MMRS.

Mike,

 

Thanks for your reply. I am working on the BF537 which does not have an operating system. do you have any suggestions?

 

Thanks.

this is a Linux forum.  typically bare metal questions go in the toolchain forums as you'd be using the bfin-elf compiler.

 

you are using the bfin-elf compiler right ?
