Ultra96v2 Modprobe wilc3000 failed

thomas-schulik

Hello,

 

I have built a new Petalinux 2018.3 image with the usage of the BSP from https://github.com/Avnet/Ultra96-PYNQ  from image_2.4_v2 and added my own hardware design from Vivado 2018.3.

 

petalinux-config --get-hw-description /path-to-sdk-folder

 

When I have booted Petalinux successfully, I would like to connect to the WiFi and I initially executed following command:

 

modprobe wilc-sdio

 

After this I get the response:

 

[   62.466155] wifi_pm : 0

[   62.468637] wifi_pm : 1

[   62.764959] wilc_sdio mmc1:0001:1: wilc_sdio_disable_interrupt

 

What is wrong with my wilc3000 firmware or the connection to the wilc3000 module?

Why the firmware can't be loaded successfully?

 

In the attachment you can find a complete UART Trace from the startup sequence.

  • I guess this is an obvious question, but have you tried using the the ultra96-pynq-image-v2.4_v2 before doing your hardware design mods?  I haven't used that particular image, but the I've used the ultra96v2-pynq-image-v2.5 and the wifi works in that image.  If the released image works, that would verify that your board is okay and that you should look at your design changes.
