using twi on bootloader

[Luccas]

Hi there!

I'm working with secure_bootloader example (SDK 12.1.0) and trying to use i2c communication on bootloader. I'm using the debug code and checking via LOG (uart), but when I added the initialization process of twi (nrf_drv_twi_init) I receive an error: :ERROR:received an error: 0x00001001!

What that error means? Is it possible to use i2c on bootloader?

Thanks, Luccas Casagrande.

It seems this error was because of one configuration of twi, in my case I was setting the priority level with wrong values. I'll try to communicate and report if success. Thanks

I am having similar problem, if you have new developments please post. Regards

My problem was solved by correcting the priority level to APP_IRQ_PRIORITY_HIGH. My config ended like:

    const nrf_drv_twi_config_t twi_config = {
   .scl                = I2C_SCL, //scl pin
   .sda                = I2C_SDA, //sda pin
   .frequency          = NRF_TWI_FREQ_100K,
   .interrupt_priority = APP_IRQ_PRIORITY_HIGH,
   .clear_bus_init     = false
};
