Hi Koichi,
Did you try to test the SPI and I2C separately on your board?
Is the SPI and I2C working if just have one module?
How did you configure both I2C and SPI, and when the SPI is stuck? Please post some code about it.
Because I don't have the Edison and MPU-9250 on my side, then you should test it and tell me the result.
Waiting for your reply!
Have a great day,
Kerry
