Tool/software:
Hey Team ,
We have some statistical bring up issue with the TCAN4550.
its appeared that the Linux drive not success to detect the TCAN4550 correctly and then the initialization is failed with the below printing from dmesg
tcan4x5x spi0.0: interface-name can2
tcan4x5x spi0.0: no clock found
tcan4x5x spi0.0: Not a tcan device ffffffff
We thought that issue around the crystal can be the route cause , and we tried to reproduce it by removing the crystal itself and connected OSC2 to gnd ( without external clock) but we got different printing from the dmesg as below
then its look that the crystal is not the rout cause of "Not a tcan device ffffffff "
do you have any idea on what may cause the detection issue ?
