There must be something wrong with the CHIP_ID read section, since I could get the correct chip_id using a custom code ? Also maybe the SPI has a maximum burst length, sending the 8K config bytes at once ? ... View more

Hello, The chip ID returned is not correct. It looks like the code writes the config before checking that CHIP_ID is accurate.  rslt = bmi2_soft_reset(dev); // bmi2.c:line 1753 write the config before chip_id Here are hardware specs. Here are pinout layouts ... View more

Hi BSTRobin, A big thank for the code example you provided, I learned a lot from it. I tried to run you example along with the BMI270-Sensor-API, I built everyting using STM32CUBEIDE 1.13.0, and could not make it run with a BMI270 sensor on a flight controller. The configs of my flight controller can be found here . The logs I get from UART : SPI Interface Error [-3] : Device not found error. It occurs when the device chip id is incorrectly read bmi270_wh_init() failed, error code: -3 I hope you can enlighten me about what I did wrong, I spent a long time trying to develop a custom driver following the BMI270 datasheet, and gave up. ...
