Use I2C RTIO driver with nrf5340

[raghuveer]

I am trying to use the ICM42688 sensor on I2C BUS with nrf5340 Application core. In the configuration, the HAS_I2C_RTIO config couldn't be enabled. Is this an MCU limitation?

Thank you.

Hi,

Rather than an MCU limitation, I would say it's not a standard Kconfig symbol related to I2C in Zephyr or Nordic SDKs. Please make sure that you use Kconfigs appropriate to the SDKs.

I found that symbol when I tried to enable I2C_RTIO. HAS_I2C_RTIO is listed as a dependency.

Maybe it is relevant: I am using SDK version v2.7.99-cs1

I see that the symbol is introduced in this commit github.com/.../06e025aeee7d145c47a4f0b3efba88b58f255eba

Hi Raghuveer,
Apologies for the delay as I got held up with another case. Do you still face the issue?

Hello, yes I still have this issue. I am using the NRF SDK commit 17ce98c9 at the moment.

Hi Raghuveer,

I have asked this internally with experts and will get back to you as soon as I get a response.
