Hello Stafno,

Thank you for the reply.
The strange thing is that although the OMAP L138 have the ability for using
more then one UART, it seems that in the u-boot, it is not well supported:
Only if I add in /common/serial.c the following line:
line 45: || defined (CONFIG_MACH_DAVINCI_DA850EVM), and same include in
/common/serial.h
then compiler error is solved. it is as if this file support several cpu's
but the OMAP is not one of them. Is It correct to add this flags in order to
support multiple serials in OMAP L138 EVM ? I tried to ask in TI forum, but
got no reply yet.

Thank you very much,

Ran
