WL1835MOD: Connect this wifi module with raspberry pi

Hi Dien,

We don't have a guide for the connecting these two devices because there is no public hardware that exists that allows both to communicate. Are you building a custom board with these two devices? Can you please mention specifically which Raspberry Pi board you are using?

We need access to the Raspberry Pi's SDIO port, and I'm not sure how feasible this is. 

Hi Sabeeh,

Thank you so much for your quick response. Yes I am trying to build a fixture with these two devices. The Raspberry Pi that I am using is version 1B+ with the chip BCM2835. 

Hereby I send you the picture shows the pinouts of the raspberry pi that I have. kindly feel free to let me know your further question. 

Thank you!

Dien

Hi Dien,

Ok, looks like you can use those pins for SDIO to the WL18xx. You will also need two more gpios for WL_EN and WL_IRQ. Lastly, you will need to configure the DTS to enable the SDIO port. Do you have any example DTS that can configure the SDIO port on these lines?

Hi Sabeeh,

Frankly speaking I do not have any example DTS on hand. Can you share with me the way how can I set the DTS in raspberian?

So far I have a glance on dts files as saved in the following link:

git.ti.com/.../dts

path: root/arch/arm/boot/dts/bcm2835-rpi.dtsi. I figure out that there is the dtsi file there but I do not know how to set this file in Raspberian in my case. I make a snapshot bellow for your reference.

Hope that it would give you a hint. Thank you!

My best regards

Dien

Hi Sabeeh,

I have turned to use the beagle bone black to follow to the instruction. Unfortunately the instruction seems to be overwhelmed with me so far. 

I have built the image on the micro SD card, but I do not know how to build the SDK. Can you give me a hand on this step?

Thank you in advance!

Dien

Hi Sabeeh,

Thank you so much for the helpful image. It does help me a lot. In the future what should I do to pursuite the idea that make the driver for the raspberry pi which helps to communicate with this wifi module.

My best regards

Dien

Hi Dien,

Sorry for the delay. We don't have an example to connect the cc33xx device to the raspberry pi. You would need to work with the raspberry pi forums to enable SDIO in DTS.
