I am experiencing an issue with the I2C device on the nRF5340(our custom board) where it is unable to read/write to the sensor, resulting in a return value of -5.(EIO)
Details:
- SDK Version: v2.6.1
- Custom Board : nrf5340-nrf7002
- Temperature sensor : SHT302x
Build Configuration in vs code: board = nrf7002dk-nrf5340-cpuapp-ns
- prj.conf:
CONFIG_I2C=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_PSA_WANT_ALG_HMAC=y
I2C project file
#include <zephyr/sys/printk.h>

const struct device *const i2c = DEVICE_DT_GET(I2C_INST);
int main(void)

bool retValue = false;
printk("Hello World! %s\n", CONFIG_BOARD);
static const unsigned char string[] = "Hello world!";
int len = strlen((const unsigned char *) &string);
if (!device_is_ready(i2c)) {
printk("i2c is not ready!\n");
} else {
printk("i2c is ready\n");
}
uint8_t command[2] = {0};
command[0] = DEVICE_ID_COMMAND_MSB;
command[1] = DEVICE_ID_COMMAND_LSB;
uint8_t command2[2] = {0};
int transferedData = 0;
transferedData = i2c_write_read(i2c, 0x44, &command, 2, &command2, 3);
printk("transferedData %d\n", transferedData);
return 0;
}
