I think i have to update the device tree. But i cannot find the files:
Hardware fragments: arch/arm/boot/dts/digi/ccardimx2/*.dtsi
Board DTS: arch/arm/boot/dts/imx28-ccardimx28js.dts
This is what i get:
[ 0.000000] Kernel command line: console=ttyAMA0,115200 root=/dev/mtdblock3 rootfstype=jffs2 rw mtdparts=gpmi-nand:0x300000(Bstrm-U-Boot),0x80000@0x300000(NVRAM),0x500000@0x380000(Kernel),0xbe00000@0x880000(RootFS),0x2f80000@0xc680000(UserFS),0xa00000@0xf600000(Device-Tree)
[ 0.151709] 80074000.serial: ttyAMA0 at MMIO 0x80074000 (irq = 233) is a PL011 rev2
[ 0.426840] console [ttyAMA0] enabled
[ 0.763651] 8006a000.serial: ttyAPP0 at MMIO 0x8006a000 (irq = 231) is a 8006a000.serial
[ 0.778549] 8006c000.serial: ttyAPP1 at MMIO 0x8006c000 (irq = 232) is a 8006c000.serial
I found in the tmp directory some identical files of "arch/arm/boot/dts/imx28-ccardimx28js.dts"
I dont know which especialy its in the tmp-directory.
