Yestoday I tested the earlyprintk stuff witout luck :-( I simply added this CMDLINE earlycon=uart,mmio,0x11100000,115200n8 console=ttyS0,115200n8 panic=1 The drivers/serial/8250_early.o is build in the kernel but without adding CONFIG_EARLY_PRINTK or CONFIG_SYS_HAS_EARLY_PRINTK. Maybe this is the problem. On the running kernel I see this. Serial: 8250/16550 driver $Revision: 1.90 $ 5 ports, IRQ sharing enabled serial8250.7: ttyS0 at MMIO 0x11100000 (irq = 0) is a 16550A serial8250.7: ttyS1 at MMIO 0x11200000 (irq = 8) is a 16550A serial8250.7: ttyS2 at MMIO 0x11400000 (irq = 9) is a 16550A The console is console=ttyS0,115200n8 .... Now I'll go more deep into the kernel. > > (Btw, which board? I'd love to get my hands on other alchemy boards to > test on). It is a customer board not available on the market. It is possible for you to connect me to this person. Maybe we can share some know how. At the moment I work on USB Analog/DVB stuff more deep on MIPS. Kind Regards, Frank
