Hello, I be tried to connect the bmi270 on my custom board, I ve verified the hardware and I ve done everything to get the software part working.
I even built my own custom target with the following defines but cannot detect the gyro .I ve tried everything, it's on spi 1 , I ve selected the spi bus and everything.
No matter what I do, I cannot get it working, tried setting every parameter, checked every resource , added it to DMA and everything

Post actual text files, not screenshots
And you still haven't provided any of the information I requested
The first two problems are you're missing the gyro define and your gyro config is incorrect
Have you read this?

Yes sir I read the manufacturer guidelines, they say use SPI 1 for it so I m connecting breakout to it, also set the spibus and mode for gyro 1 , set all the resources for cs ext and spi pins, added all the required defines and built my own target what else do I need , check the photo I post of target.h
The photo I posted above was when I was trying it with gyro 2 , I changed the gyro to use to second , I was just trying it out but it didn't work
I will again try it double checking the hardware once again let's see where it goes and I will post full CLI dump

SPI2 should work, but nothing else you have posted so far is correct so it's not surprising its not working
you need to include the BMI270 in the defines so Betaflight is compiled with the correct driver, and you need to set the gyro properly in the BF Config
FInd a similar config and flash a cloud build using BF Configurator to rule out issues with your build environment
And fix your config file

Hello , I tried a different gyro, mpu6500 which worked perfectly, I guess I have hardware issue, one more thing I wanted to ask you is bmi has a intial sequence that switches it from i2C to spi , does betaflight driver do that

Okay great it's my issue then

It's my first time soldering a lga package ,maybe it didn't get soldered properly. Yest I also got the baro working
