ATWILC1000-MR110PB Linux SPI Driver and Communication

Tue Oct 02, 2018 3:35 pm

Hello;

I have been working on the IMX28 processor development kit and I want to implement atwilc1000-MR110PB wifi module with spi communication . I have done all the required spi connections and driver implementations. Driver successfully probed to the system.

Also for SPI communication, I implemented 2-parallel 2.2M Ohm for to get 1M Ohm pull-up resistor to the SDIO_SPI_CFG pin. Then make SDIO_SPI_CFG connection to the VDDIO pin. Because of the, all grounds are connected togather I just gave GND from just one pin. Also I have experienced the 30 ms dleay between CHIP_EN and RESETN pin. In that system , which everything should work fine, I cannot get the CMD response from the WIFI module. I think the SPI_CFG pin is not correctly configured. I cant talk with the module.

These are my logic analyzer outputs,

I really didnt understand what Am I missing ?. I would be very appreciated if you help me about that problem.
Thank you.

Best Regards

What kernel version are you using?
Which version of the WILC1000 driver are you using?
Where are the "images"?
