Where is my uart? Digi Linux -> Yocto Linux


I am chaning from Digi Embedded Linux to Yocto Linux. I created i using bitbake but now wondering, where do i find the previous used uarts?

Previously I used “/dev/ttySP4”.

Thank you!

dmesg | grep tty
should give you an idea

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)

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.
