Hello,
I need to use gprs modem with ppp over uart0, but something blocks the communication. The uart0 runs well over minicom, but not over ppp. When I use another uart, the ppp runs well. But I have to use uart0. The uart0 is set like debug port in u-boot and I think, that this is the reason. I don't know how to disable it.
Maybe disable CONFIG_REQUIRE_SERIAL_CONSOLE in u-boot config file ?
Thank you
Tomas
