Hello,
I'm still struggling to get our AM335x/TiWi-R2 board working properly. The wifi chip gets detected but continually fails with SDIO errors (wl1271_sdio mmc1:0001:2: sdio read failed (-84)). One thing I noticed that seems different to other descriptions of what to expect is that I can not see a wl1271 GPIO interrupt listed under /proc/interrupts.
All of the initialisation succeeds - I set the am335xevm_wlan_data.irq to the correct value using 'am335xevm_wlan_data.irq = gpio_to_irq(GPIO_TO_PIN1, 13);' and the subsequent call to 'wl12xx_set_platform_data(&am335xevm_wlan_data);' succeeds but, as above, I cannot see the interrupt listed.
Is there something extra I need to do to properly register the interrupt with the kernel? I'm not sure if this interrupt issue would cause the sdio problems I'm seeing, but it might be the case, so I'd like to get everything into the correct state before proceeding.
Any suggestions on ensuring the interrupt gets properly registered?
Regards,
Andrew.
