Hello,
I'm currently using two 16550s UARTs with a BF532 (in my case, FPGA
embedded UARTS). The 8250.c driver needs a slight modification that is
currently in the Blackfin uClinux CVS. An example of how the UART
addresses and interrupts are defined can be found, also in the CVS, in
arch/blackfin/mach-bf533/boards/H8606.c.
Regards,
Javier

Hi all,
I'm new here and don't know if this is the right place to ask about Blackfin
running uClinux and UARTs.
I need to add some kind of UARTs to a BF561 project. I would like to use a
quad UART (16554) with FIFO connected to the parallell bus in a way similar
to the Ethernet/USB extender board from ADI.
Is there a "standard" for which addresses and interrupts that should be used?
I have noticed that there are device drivers for these UARTs available. Do
they work "out of the box" with a Blackfin and an external UART?
Is there a better way?
TIA
