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.)

Since then, the log below has continued to appear.

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