How did you configure wpa_supplicant for this? Assuming you are using
ap_scan=1 (which is the default), something as simple as this should
allow connection to a mixed WPA/WPA2-Personal AP:

network={
    ssid="foo"
    psk="12345678"
}

since the defaults enable both options. More explicitly, you could use
these parameters to enforce the stronger option if you know the AP
enables WPA2-Personal/CCMP (which it will ,in mixed mode configuration):

network={
    ssid="foo"
    psk="12345678"
    proto=RSN
    key_mgmt=WPA-PSK
    pairwise=CCMP
    group=TKIP
}


Please send wpa_supplicant debug log showing the issue if you cannot get
the connection working based on these notes.
