I am making a program that uses MINISASTOCSI (OV5640) and cortex-M4 to communicate by I2C with iMX8MminiEVK.
However, I cannot confirm the response from the I2C camera.
The I2C driver uses MCUexpressoSDK (SDK_2.7.0).
When I use an oscilloscope to look at the I2C SDA and SCL lines, I have confirmed that the OV5640 does not respond with an ACK to the I2C slave ID but becomes a NACK.
Slave address is set to 0x3c.
"PWDN" and "RESETB" of OV5640 are controlled by referring to "ov5640_probe" of "ov5640_v2.c" of "i.MX Linux Rev. L4.19.35_1.1.0, 11/2019".
Is there anything else to be aware of?
