Anyone using Talon Mirage IoT card, or another WL18xx - based device with MangoH Red WP7607/ 8/9 board?

Hi ,

Anyone verified Talon Mirage WiFi IoT card, or another WL18xx - based device with MangoH Red WP7607/ 8/9 board ?

I need to add WiFi feature to MangoH Red WP7607/ 8/9 board for video streaming. It seems onboard WIFi chip has limited through put with UART interface .

The WiFi uses SDIO not UART. I have verified that the WiFi works although I have not done any throughput testing as we don’t need it at the moment.

Hi,
You mean Talon Mirage WiFi IoT card (WL1831, SDIO interface ) with MangoH Red WP7607/ 8/9 board ?

If yes, Let me know how to disable on board wifi module (uart interface)and enable external Talon Mirage WiFi IoT card .

Hi,

Let me know how you got linux driver for talon mirage wifi module . Is it part of deault BSP package of mangoH Red board?

The Talon WiFi IoT card based on the TI WL18xx chipset supports WiFi on mangOH Red without much difficulty. Off the top of my head, I think the only thing you would need to do to make it work is comment out this line in the mangOH Red system definition file:

If you run into any issues with the card, please let us know and I’m confident that we can work through them. I have used the card many times in the past.

HI Dfrey,

Thanks for reply. Will reply after checking the same .

In between I have one query about Hardware setting of mangoH Red board IOT connector (CN306) SDIO signals. .

It seems IOT connector SDIO data signals are connected to UART1 control signal (DTR/DSR/DCD/RI) of Wp76XX module (J200) .

Did you isolate those SDIO signals from UART1 port control signals while do testing WL1831 based IOT WiFi card . There is an option to isolate with resistors (R584 to R587) .

Hi Dfrey,

Attached the resistor isolation of option between SDIO data signals and UART1 control signals in MangoH red board.

Did you isolate those SDIO signals from UART1 port control signals while do testing with WL1831 based IOT WiFi card ?

Hi Dfrey,

With reference to the above reply for enabling TI WL18xx driver on the MangOH Red board, the yocto has the wl18xx driver support.

Downloaded the legato 19.02.0, but i dont find the red.sdef file. There is only default.sdef file.

Can you help me understand where i am going wrong.

The red.sdef that i am referring to comes from the mangOH git repository: https://github.com/mangOH/mangOH

If you have the “HL_MODE” dip switch in the off position (which you should for WP modules), then the connections to the UART1 signals shouldn’t matter.

Hi dfrey,

I did follow the steps mentioned in the link provided in mangOH git.

I get wifi.sinc file not found when “make red_wp76xx”. Request your input here.
