- Subject: [ECOS] dual uart driver
Hi,
I am implementing a 2nd uart driver in eCos on the
Broadcom BMC91112 mips chip. The first uart driver
is working fine which is provided by Broadcom. I have
the following questions on the 2nd uart driver:
1. I plan to use a different uart base address and a
different interrupt number for the second uart. Can
I share the same ISR routine for both uarts?
2. In which situation should I use polling and
interrupt method? I plan to use the interrupt
method.
3. Where can I get sample implementation for 2 uart
driver?
Thanks.
Chi Lam
