Topic: [Setup & Troubleshoot] Bitmain AntMiner S1 180GH/S miner - page 69. (Read 452359 times)

Wow so fast? And how much is it to pay at costums? I saw some complaints that its more to pay as before...

Around 3 working days

How long does it take on average to get Antminer S1 to europe?

Nice

Heh. You do know that I wrote the original USB support code in cgminer right?

Anyway, the way it works is there is custom hardware on the WRT daughter board that converts one or two 'blades' to a USB device for cgminer to access it.

Yes I asked about this when they first came out - if they could make a daughter board that is just purely a USB connection to the two 8 cable board connectors.
I never got a reply about that.

Found that device id in Bitmain's cgminer repo, so I can confirm that is correct.  Since we have two blades and only one device ID, I think we can conclude that the blades are not USB.  I think there must a separate controller chip that is communicating with the SOC using an on-board USB interlink.  Probably some custom serial hardware, so much for rolling my own controller :-(  Sure hope Bitmain replies soon.

Thx. I'll hit them with this mod if they act up again.

I'll at least just extend the fan cable myself, but that's a good observation.

When switching the fan around you'll notice there is one screw that is not a hex, you'll need to swap that one also so that the fan fits snugly on the other side 

This is the mining 'blade':
Bus 001 Device 004: ID 4254:4153

got four antminers in the mail today.  One of them has a bad controller, the chains are not found.  

I noticed in the log that there's a problem with the USB:
Wed Dec 31 19:00:11 1969 kern.err kernel: [   11.870000] usb 1-1.1: device descriptor read/64, error -32

And this in dmesg:
[    7.150000] usb 1-1.1: unable to read config index 0 descriptor/all
[    7.150000] usb 1-1.1: can't read configurations, error -32
[    7.260000] usb 1-1.1: new full-speed USB device number 6 using ehci-platform
[    7.290000] usb 1-1.1: device descriptor read/all, error -32

When I run lsusb on a good miner I get:
Bus 001 Device 002: ID 0409:005a
Bus 001 Device 001: ID 1d6b:0002
Bus 001 Device 004: ID 4254:4153

But with the bad controller I only get:
Bus 001 Device 002: ID 0409:005a
Bus 001 Device 001: ID 1d6b:0002

Does anyone know anything about the interface of the mining blades?  If they're just a USB interface then I should be able to build my own controller and compile the software from bitmains repos.  Kind of strange that there's only one missing USB device though, if they are USB.

I cant wait to get home and try this....  i have 3 whinning at full speed..  the sound drowns at 40 others

I don't think it affects anything else.
But I wouldn't rule it out.

I disabled NTP on my Ants and I have no problems with my speeds 

Nice to hear, glad to help 

I fixed it

Apparently I didn't notice the cnt=0 before all the rest.
That has to be commented out as well for it to work.

So if you want to manually remove the NTP in the v1.5 Ant you should comment out all the following:

cnt=0
 if [ ! -f /tmp/cgminer-ntpd-done ]; then                               
               while [ "$NTPD_RET" != "0" ]; do                               
                       ntpd -d -n -q -N \                                     
                           -p 0.openwrt.pool.ntp.org \                       
                           -p 1.openwrt.pool.ntp.org \                       
                           -p 2.openwrt.pool.ntp.org \                       
                           -p 3.openwrt.pool.ntp.org                         
                               cnt=$ (($cnt+1))
                               if [ $cnt -gt 2 ];then
                                        echo cnt
                                        break
                              fi
                                                                             
                       NTPD_RET=$?                                           
               done                                                           
                                                                             
               touch /tmp/cgminer-ntpd-done                                   
       fi 

OK,
I have checked both version of my /etc/init.d/cgmirer file and THERE IS a difference.

The older version is like this:

#       if [ ! -f /tmp/cgminer-ntpd-done ]; then                                
#               while [ "$NTPD_RET" != "0" ]; do                                
#                       ntpd -d -n -q -N \                                      
#                           -p 0.openwrt.pool.ntp.org \                        
#                           -p 1.openwrt.pool.ntp.org \                        
#                           -p 2.openwrt.pool.ntp.org \                        
#                           -p 3.openwrt.pool.ntp.org                          
#                                                                              
#                       NTPD_RET=$?                                            
#               done                                                            
#                                                                              
#               touch /tmp/cgminer-ntpd-done                                    
#       fi  


The New one:

       if [ ! -f /tmp/cgminer-ntpd-done ]; then                                
               while [ "$NTPD_RET" != "0" ]; do                                
                       ntpd -d -n -q -N \                                      
                           -p 0.openwrt.pool.ntp.org \                        
                           -p 1.openwrt.pool.ntp.org \                        
                           -p 2.openwrt.pool.ntp.org \                        
                           -p 3.openwrt.pool.ntp.org                          
                               cnt=$ (($cnt+1))
                               if [ $cnt -gt 2 ];then
                                        echo cnt
                                        break
                              fi
                                                                              
                       NTPD_RET=$?                                            
               done                                                            
                                                                              
               touch /tmp/cgminer-ntpd-done                                    
       fi  


Does anybody know how I can go about it?

That was a very good suggestion! Running the fan from the 2nd blade actually helps, it spins according to spec now. Thank you!
