With current git (and 2.6.23-rc1), nothing shows up on the serial console on IP32. Ricardo Mendoza commented on this on IRC: > I think it was that using iobase member in the plat_serial8250_port > struct was not working, swapping to membase gave console messages > but kind of stopped printing messages at some point (further in than > first line of C tho) He also sent me a patch to test. With this patch, I get serial console output - but only until: | Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled | serial8250.0: ttyS0 at MMIO 0x0 (irq = 53) is a 16550A | console [ttyS0] enabled Maybe Ricardo can post his patch for comments and someone can look into the second issue. -- Martin Michlmayr http://www.cyrius.com/
