Hi @keven.wu-Q
Thanks for your reply.
I am able to operate GPIO.
Currently, I am stuck at I2C operation. I want to enable SENSOR_I2C to interface another i2c device. Cloud please help me to how to add it.
When I go through the “Pepheral” document I found the below notes.
1. TrustZone opens only 1 I2C for customers to use by default, that is Q UPV3_0_SE2. If you need to
enable or disable other I2Cs , refer to the methods in Chapter 7.2 for I2C configuration. Please
contact Quectel Technical Supports to obtain tz image file before I2C configuration.
2. Each SE core can only support one of UART, SPI, or I2C simultaneously.
When I apply the command “ls /sys/class/i2c dev/” I got “i2c-0”. I go through document and I thing pins for I2C-0 are “TP_I2C_SCL” and “TP_I2C_SDA”. Please current my understanding.
Please help me to add support for “SENSOR_I2C”.
