    I get firmware error -16 (BCME_BUSY)




      We are using a Broadcom BCM4339 (SP-ZZ1CK-E, Tentative P/N :LBEE5ZZ1CK-TEMP) and we have issues when we are connecting to networks.


      My method to reproduce the issue is to connect to a certain AP then connect to another AP, then again, again, usually after 5-6 connection I can get the error


      [ 2128.810878] brcmfmac: brcmf_fil_cmd_data Firmware error: BCME_BUSY (-16)

      [ 2128.810888] brcmfmac: brcmf_run_escan: error (-52)

      [ 2128.810892] brcmfmac: brcmf_fil_cmd_int_set ifidx=0, cmd=10, value=0

      [ 2128.810896] brcmfmac: brcmf_proto_bcdc_set_dcmd Enter, cmd 10 len 4

      [ 2128.810899] brcmfmac: brcmf_cfg80211_scan: scan error (-52)


      I would like to know what could cause the firmware to return an error and that -52 is an Invalid Exchange. I don't know if that's between the AP and the chip or something else?


      If you need any more details, I can provide Netlink monitoring packets.
