The problem is here, the rest are just other problems because of this. The driver should abort the initialization at this point. The ucode does not start after it was loaded onto the device in brcms_ucode_download(). I never had such problems when using b43. >> [ 80.240000] ieee80211 phy1: wlc_coreinit: txfifo mismatch: ucode size >> 111 driver size 28518 index 5 >> [ 80.380000] ieee80211 phy1: wl1: wlc_suspend_mac_and_wait: waited >> 83000 uS and MI_MACSSPNDD is still not on. > > In several scenarios the driver puts the d11core in suspended state. > This message indicates d11core does not end up in suspended state. > Normally, means the d11core got stuck.

On b43 I am using firmware version 666.2 from wl 5.100.138, but also older versions are working. On brcmsmac I am using bcm43xx-0.fw and bcm43xx_hdr-0.fw from the linux-firmware git repo. Does the ucode you provide in bcm43xx-0.fw and bcm43xx_hdr-0.fw support rev 17 ieee80211 cores? For b43 it is the same file for all n-phy based cores rev >= 16, so for wl it should be the same, but have you added some special handling into this firmware for brcmsmac?
