Spiflash, I use the cpio.gz root file system, I have three devices under i2C, iiO is hanging one device:
root@TinyLinux:~# ls /sys/bus/i2c/devices/
0-0040 0-004e 1-004e i2c-0 i2c-1 i2c-2 i2c-3
root@TinyLinux:~# ls /sys/bus/iio/devices/
iio:device0
But when I use flex-installer -b XXXXX -d /dev/mmcblk1 to install the system to the MMC device and boot with MMC, The I2C device and IIO device cannot be found. What's the reason for that ??
root@localhost:~# ls /sys/bus/i2c/devices/
i2c-0
root@localhost:~# ls /sys/bus/i2c/devices/i2c-0/
consumers device/ name of_node/ subsystem/ uevent
delete_device i2c-dev/ new_device power/ suppliers
Add new findings：
I with DTC decompiled /boot/fsl-lx2160a-dtb.dtb, found not I was using the device tree。why didn't I modified device tree why compiled into it ？ Do I need to replace the fSL-lx2160a-dtb.dtb file in the root file system? How do I replace it ?
