We have a custom designed board(tx2),everything is ok when the version of JetPack is 3.3.
Now we try to port it from JetPack3.3 to JetPack4.2. We use Pinmux file(Version1.05). And the usb,i2c,spi all ok. Follow "Sensor Driver Programming Guide" of "NVIDIA_Tegra_Linux_Driver_Package"(version 4.2) . We has
tried “Version 1.0” and “Version 2.0”.But boot failed.
Now we try to use "Version 1.0". we port the sensor driver file from Jetpack3.3 to Jetpack4.2,just delete:
priv->subdev->entity.type = MEDIA_ENT_T_V4L2_SUBDEV_SENSOR;
and modify function from “media_entity_init” to “tegra_media_entity_init”
From the minicom.txt,It seems the ar0134 has been recongnized at time 3.537111 and time 3.635036 . We just don't know why tegra-vi4 crashed.
