Thanks, the different is between the 61th and 62th commit. I have to type "iw wlan0 scan" for the 62th commit firmware to connect after running wpa_supp.
They all had: 
wlan0: CTRL-EVENT-SCAN-STARTED
wlan0: SME: Trying to authenticate with 04:f0:21:0e:38:be (SSID='ath10k' freq=5280 MHz)
wlan0: authenticate with 04:f0:21:0e:38:be
wlan0: direct probe to 04:f0:21:0e:38:be (try 1/3)   
wlan0: direct probe to 04:f0:21:0e:38:be (try 2/3)
wlan0: direct probe to 04:f0:21:0e:38:be (try 3/3)
wlan0: authentication with 04:f0:21:0e:38:be timed out

But the first firmware continue to do this: 
wlan0: SME: Trying to authenticate with 04:f0:21:0e:38:be (SSID='ath10k' freq=5280 MHz) 
wlan0: authenticate with 04:f0:21:0e:38:be    
wlan0: authenticated
 wlan0: Trying to associate with 04:f0:21:0e:38:be (try 1/3)
 wlan0: associate with 04:f0:21:0e:38:be
 wlan0: associated  

While the second one keeps saying:
wlan0: CTRL-EVENT-SCAN-STARTED
