For 824x the detection code for the on-chip UART does NOT currently detect it as a 16550A. There is a patch that Tom Rini and I are working on getting accepted by the serial maintainers, that should fix this.
However, its not clear to me from your email if you also have a ST16C2552 in addition to the DUART on the 8240. - kumar On Wednesday, September 17, 2003, at 08:37 PM, Yuxiao Xi wrote: > > Hi,all, > Does Linux support UART ST16C2552 ? > There is a UART ST16C2552 on my board with CPU ppc8240. > While the linux system booting,sometimes function autoconfig(struct > serial_state * state) in ./drivers/char/serial.c detected ST16C2552 as > 16450,sometimes as 8250,can anyone tell me why? > > !!!!!!!!!!!!!!!!Yuxiao Xi > !!!!!!!!!!!!!!!!xiyuxiao at harbournetworks.com > !!!!!!!!!!!!!!!!!!!!2003-09-18 > ** Sent via the linuxppc-embedded mail list.
