Yes, this turned out to be the case.  Now the chip appears to be powered up and i
get nice and very promising:

[   33.960683] wfx-spi spi0.0: started firmware 3.17.0 "WF200_ASIC_WFM_(Jenkins)_FW3.17.0" (API: 3.12, keyset: C0, caps: 0x00000000)                                               
[   33.991401] wfx-spi spi0.0: sending configuration file wfx/wf200.pds                                                                                                            
[   34.006885] wfx-spi spi0.0: enable 'quiescent' power mode with wakeup GPIO and PDS file wfx/wf200.pds
[   34.007212] wfx-spi spi0.0: MAC address 0: 84:fd:27:71:72:f7

[   34.045198] ieee80211 phy0: Selected rate control algorithm 'minstrel_ht'

However, when i do "ip link set dev wlan0 up" i get:

[  118.481024] wfx-spi spi0.0: timeout while wake up chip             
[  118.501051] wfx-spi spi0.0: timeout while wake up chip        
[  118.521142] wfx-spi spi0.0: timeout while wake up chip            
[  118.541059] wfx-spi spi0.0: max wake-up retries reached   

Could this be an issue with:

"enable 'quiescent' power mode with wakeup GPIO and PDS file wfx/wf200.pds"

from the kernel log?


thanks,
