Migrating from nrf5_SDK to nrf connect sdk

[kclauah]

Hello,

I am migrating code from nrf5_SDK_17.0.2 to nrf connect sdk v1.6.1. The board i am using is nrf52dk(nrf52832) connected with adafruit LSM6DSO.

Everything works fine on nrf5_SDK which based on modified example twi_sensor. But when I run lsm6dso example from zephyr\samples\sensor\lsm6dso, it says

Cannot set sampling frequency for accelerometer. -134

I have tried manually write register to i2c address like what I does on nrf5_SDK but hard fault occurs.

    //uint8_t buf[2] = {0x10, 0x10};
    //int ret = i2c_write(dev, buf, 1, 0x10);
    int ret = i2c_reg_write_byte(dev, 0x6a, 0x10, 0x10);
    if (ret < 0){
        printf("cannot i2c_burst_write");
    }else {
        printf("custom i2c_burst_write");
    }

Any help would be appreciated.

Hello,

And the suggestion from @anangl works for me.

How can I report a bug here?

Thanks for the feedback! I’m glad to hear you could solve the issue. I will report this internally.

Hello again,

I got some feedback from our development team:

• There is a commit in Zephyr that adds a possibility to handle flash-located buffers to i2c. However, I’m not quite sure yet in which NCS release this will be included.
• Handling DSP310 requires an extra entry in the devicetree that creates an additional buffer in RAM for a specific i2c instance: flash-buf-max-size; so still an action is required from the DPS310 driver user prior to using it

Regards,

Markus
