BMI 270 chip ID 0x26 and Internal status 3

[Lolo64240]

Hi,

I have stange issues with my BMI270. The first is that its chip ID is different than the expected one (0x26 instead of 0x24) and once changed in my code in order to continue configure it, so when all finished the Internal status return 3 (invalid driver)!!

I already use BMI270 on same cards without any troubles. 

What has changed? Is there new driver? I'm using the v2.63.1.

Thank you!

Hello Lolo64240,

When you read BMI270 chip ID via I2C or SPI, what is its actual HW communication waveform?

[Lolo64240]

Hello,

I use SPI and waveform seem to be perfect, 0-3V amplitude. at 1Mhz.

the marking is pretty strange : 5N, ON2

That doesn't match with datasheet...

Hello Lolo64240,

I mean the actual data in waveform.

0x26 is the chip ID of BMI220. By the way, where you got the stock?

Hello BSTRobin,

I got them from a brocker... 100 units.

Is the marking also indicates that is a BMI220??

I have difficulties to find its datasheet. Can you provide it to me?

I need its driver, where can I find it? Unless this is a new component without no datasheet available for the moment?

Thank you again very much,

Laurent
