Error while inserting the STM Linux driver #6

Closed SPrab3 closed 3 years ago

SPrab3 commented 3 years ago

hello,

I am trying to get the LSMDSO32 to work with https://github.com/STMicroelectronics/STMems_Linux_IIO_drivers branch 4.19 built on 5.4 kernel.

I am able to build the kernel image on 5.4

But when i try to insmod the modules i get the following errors.

insmod st_lsm6dso32.ko

[ 3073.698696] st_lsm6dso32: Unknown symbol devm_iio_kfifo_allocate (err -2)

[ 3073.706025] st_lsm6dso32: Unknown symbol devm_iio_triggered_buffer_setup (err -2)

insmod: failed to load st_lsm6dso32.ko: No such file or directory

insmod st_lsm6dso32_i2c.ko

[ 3079.860966] st_lsm6dso32_i2c: Unknown symbol st_lsm6dso32_probe (err -2)

insmod: failed to load st_lsm6dso32_i2c.ko: No such file or directory

device tree:

lsm6dso32@6a {

compatible = "st,lsm6dso32";

reg = <0x6a>;

};

Hi, st_lsm6dso32 ko exports some symbols for the st_lsm6dso32_i2c module but it need iio framework to be already loaded into the kernel so I suggest to use modprobe st_lsm6dso32_i2c instead of insert each modules
