Hi,
I am trying to write a simple application that uses I2C on a nrf5340 DK, assigning SCL to P0.9 and SDA to P0.10, using the app core ns .
The application builds without issues and after being written to the board I get the following messages
Pins have been configured as secure. GPIO port: 0x00000001 Pin: 0x00000000 Pin: 0x00000001 [Sec Thread] Secure image initializing! Booting TF-M v2.0.0-ncs2 [DBG][Crypto] Initialising Mbed TLS 3.5.0 as PSA Crypto backend library... complete. FATAL ERROR: BusFault
My nrf5340dk_nrf5340_cpuapp_ns.overlay file has the following content
&i2c1_default {
group1 {
psels = <NRF_PSEL(TWIM_SDA, 0, 10)>, <NRF_PSEL(TWIM_SCL, 0, 9)>;
};
};
&i2c1_sleep {
group1 {
psels = <NRF_PSEL(TWIM_SDA, 0, 10)>, <NRF_PSEL(TWIM_SCL, 0, 9)>;
low-power-enable;
};
};
&i2c1 {
compatible = "nordic,nrf-twim";
status = "okay";
pinctrl-0 = <&i2c1_default>;
pinctrl-1 = <&i2c1_sleep>;
pinctrl-names = "default", "sleep";
};
I assume it is a configuration issue rather than code, since my app doesn't get to start and do its thing.
What am I missing ?
