pca953x 2-0032: failed writing register

Question asked by controlx on Oct 9, 2014
Latest reply on Apr 16, 2015 by Inho Jeon

i tried to build a new image via Yocto. i build base-core-image with iproute2, i2c-tools, libsocketcan and canutils included (same with fsl-image-gui). On Start-Up there is always a failure "pca953x 2-0032: failed writing register". But on the schematic of Sabre AI i can't see any pca953x Controller. The i2c Portexpanders are max7310!

 

Same failure comes up if i type "ip link set can0 up type can bitrate 125000"

In my opinion it seems like that the Controller will write to a Portexpander but there is an other configurated?!

 

BB_VERSION = "1.20.0"

BUILD_SYS = "x86:64-linux"

NATIVELSBSTRING = "Ubuntu-14.04"

TARGET_SYS = "arm-poky-linux-gnueabi'

MACHINE = "imx6qsareauto"

DISTRO = "poky"

DISTRO_VERSION = "1.5.3"

 

I've seen this failure too on posts in the Forum but there were no Solution for it!

 

Hope anyone can help me
