Hi Liu

We have finalized zephyr 1.6 version for our project

there is any patch available for zephyr 1.6 , which I can install and use ARC to directly access GPIO including AON_GPIO and SPI ?

Please help and reply

Best regards
Mahendra

Post 1.6. You need to use master. You do not need x86 at all.

Thanks

Hi Liu

As you have stated below

"Zephyr drivers for SPI and GPIO were updated recently to allow ARC to directly access GPIO including AON_GPIO and SPI. You do not need x86 at all"

Is this done in zephyr 1.6 ? Even AON_GPIO can I declare and use directly at ARC ?

Please Note we have connected bma255 at SPI lines of x86.


Best regards

Zephyr drivers for SPI and GPIO were updated recently to allow ARC to directly access GPIO including AON_GPIO and SPI. You do not need x86 at all.

Please see the updated driver and sample app for BMI160 (top of the free, master).

Hi

We have connected an Accelerometer to the x86 core of C1000 (Quark_se) through SPI interface.
Interrupt line of accelerometer is also connected to the AON_GPIO_3

Now I need to route the SPI connection of x86 to Arc core. Is that possible ?

Any sample code in zephyr I can refer for this activity ?

Best regards
Mahendra
