@veye_xumm 对的，所以我感觉很奇怪。下面是我修改的install_driver.sh
echo "Add cma=128M to /boot/firmware/cmdline.txt "
echo "--------------------------------------"
sudo sed 's/cma=128M//g' -i /boot/firmware/cmdline.txt
sudo sed 's/[[:blank:]]*$//' -i /boot/firmware/cmdline.txt
sudo sed 's/$/& cma=128M/g' -i /boot/firmware/cmdline.txt
echo "Installing the $driver_name.ko driver"
echo "--------------------------------------"
sudo install -p -m 644 ./driver_bin/$(uname -r)/$driver_name.ko /lib/modules/$(uname -r)/kernel/drivers/media/i2c/
sudo install -p -m 644 ./driver_bin/$(uname -r)/$driver_name.dtbo /boot/firmware/overlays/
sudo /sbin/depmod -a $(uname -r)
echo "reboot now?(y/n):"

谢谢！

@homer 正常来说是会进入probe的。

@veye_xumm 你好！ log 如下，我debug 其他I2C设备时，没有外接i2c设备是可以进入probe的，只是I2C read or write failed而已，但cssc132.ko发现进入不了cssc132_probe.

@veye_xumm 你好！目前发现cssc132.ko进入不了probe，是必须外接cssc132 camera module才能进入probe吗？谢谢！

@homer said in CSSC132 driver load 问题:

系统重新启动后，系统会自动insmod cssc132.ko吗? 谢谢！

是的

@homer 执行安装脚本之后，系统会自动插入module，不需要再手动操作了。
