Hello, I ve been trying to get a bmi270 working, I ve designed my own board and wanted to work with 4 wire spi but it didn't work. I also got to know about the pulse needed on the CS pin at startup to get it into SPI mode but none of it works. I am also not able to access it on i2C mode. Is there any way to know I ve damaged my chip as the pins are not short seems fine. What am I missing here ?
