BHI260AP i2C interface

[mmgg]

Hello

BHI260AP is being implemented on the board.

I confirmed that I read the register such as i2c communication and chip id.

The error occurs while loading firmware as shown below.
(We changed the firmware name to the one we used before.)

Is there a sequence for firmware loading or if the way I did it is wrong?

Hi mmgg,

Ensure that you are not interrupted while downloading the firmware.
Where is your picture?

[mmgg]

Hi, BOSCH

Error in Read Post Mortem portion while downloading firmware.
I wonder what the reason is.

The picture of the error part looks like the red square below, is that right?

This is causing a lot of delay, so if you can reply quickly.

Thanks

Hi mmgg,

Could you strictly refer prevous reference code and see it again? Currently we can't reproduce your problem with reference software code.

[mgchoi]

HI, BOSCH

I don't know what it means to be proactive reference code.
I only have the code I gave you up there, but there is no other code.

Thanks

[BSTRobin]

Hi mmgg,

If you think the code doesn't any problem, you could capture hardware communication waveform with logic analyser and check the actual whether the actual software execution meets the software code expectations.
