[GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning

[suchmoon]

What raspi are you guys using? I've never used one but contemplating it now.  If someone could provide an amazon link that would be great.

I bought this one:
http://www.amazon.com/CanaKit-Raspberry-Basic-Clear-Supply/dp/B00DG9D6IK

Includes power supply and case. If you don't need a case and have a spare micro-USB power supply, you can get a bare board for ~$40.

You will also need an SDHC card (full size, not micro), 8GB or larger.

How to get Scripta working as it was intended

Follow the instructions by Darkfriend77 below but when you get to step 6, go to directory opt/minepeon/bin and remove the original cgminer there (rm cgminer). Now copy the new cgminer into this folder to replace the original and chmod it as below.
Now go to directory opt/minepeon/startup and edit the file miner-start.sh with nano.
Change the line -

Code:

sudo /usr/bin/screen -dmS cgminer /opt/minepeon/bin/cgminer -c /opt/minepeon/etc/miner.conf

to

Code:

sudo /usr/bin/screen -dmS cgminer /opt/minepeon/bin/cgminer --scrypt --no-submit-stale --gridseed-options=baud=115200,freq=850 -c /opt/minepeon/etc/miner.conf

Lastly apply the stability fix.
Now you can close ssh and restart your pi and it should automatically fire up your gridseeds and start mining.

Step by Step Raspberry SCRIPTA Installation:

• 1 - SD Formatter (link) clean up your SD Card. At least a 4GB SD.
• 2 - Download the SCRIPTA Image (link)
• 3 - Win 32 Disk Imager (link) and write the scripta image on the SD Card.
• 4 - Put the SD Card into your Raspberry.
• 5 - SSH access on port 7722, user: root / psw: scripta
• 6 - Use WinSCP (link) to move over the latest rasp cgminer for gridseed (https://db.tt/UygLkqwd) or Use PuTTY (link)

Code:

wget https://db.tt/UygLkqwd -O cgminer

• 7 - Go to the location where you copied over your cgminer and do "chmod 777 cgminer"
• 8 - Go to the SCRIPTA Web GUI, under Miner hit Miner commands, STOP
• 9 - Go to the location where you copied over your cgminer and run it from there using these commands:

Code:

./cgminer --scrypt -o <miningpooladdress:port> -u <user> -p <pw> --gridseed-options=baud=115200,freq=850

Stability-Fix:

Code:

sudo nano /boot/cmdline.txt

Add the following code at the end of the first line (on the same line as the other text, DO NOT add new line!)

Code:

slub_debug=FP

Has anyone figured out how to overvolt yet?  I see this in the gridseed driver...

typedef struct s_gridseed_info {
   enum sub_ident   ident;
   uint32_t   fw_version;
   struct timeval   scanhash_time;
   int      nonce_count[8];  // per chip
   int      error_count[8];  // per chip
   // options
   int      baud;
   int      freq;
   unsigned char   freq_cmd[8];
   int      chips; //chips per module
   int      voltage;
   int      per_chip_stats;
}
Aand later on this method:

static void gc3355_increase_voltage(struct cgpu_info *gridseed) {
   uint32_t reg_value;

   // Put GPIOA pin 5 into general function, 50 MHz output.
   if (!gc3355_read_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_CRL_OFFSET, &reg_value)) {
      applog(LOG_DEBUG, "Failed to read GPIOA CRL register from %i", gridseed->device_id);
      return;
   }
   reg_value = (reg_value & 0xff0fffff) | 0x00300000;
   if (!gc3355_write_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_CRL_OFFSET, reg_value)) {
      applog(LOG_DEBUG, "Failed to write GPIOA CRL register from %i", gridseed->device_id);
      return;
   }

   // Set GPIOA pin 5 high.
   if (!gc3355_read_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_ODR_OFFSET, &reg_value)) {
      applog(LOG_DEBUG, "Failed to read GPIOA ODR register from %i", gridseed->device_id);
      return;
   }
   reg_value |= 0x00000020;
   //reg_value &= 0xFFFFFFDF;
   if (!gc3355_write_register(gridseed, GRIDSEED_GPIOA_BASE + GRIDSEED_ODR_OFFSET, reg_value)) {
      applog(LOG_DEBUG, "Failed to write GPIOA ODR register from %i", gridseed->device_id);
      return;
   }
}

Looks to me like we pass an int as the argument voltage and it will add it to the base voltage value(which i think is set to 0, if I'm reading the header right), maybe?  But then it also says gpio(general purpose input output?), which is usually a general purpose pin header on the pcb itself, right?  I'm no developer/hardware engineer, anyone want to comment?

You can set voltage=1 in your config, but it turns out that will actually lower the core voltage.

How to get Scripta working as it was intended

....

thx a lot .. will update this ... :-)

[thedue]

So is there any way to control the fans? (cgminer, wiibox...?) automatically or even manually?

[mrmining]

consider to use this asic..every body think it good??

[darkfriend77]

I posted this in another thread and did not get a response. Are some of the control units being sent out with a virus? I bought this one from atari02. It seems to be hashing okay in the wiibox but does not always show up as hashing in scryptguild.

Original message:
I had root access with SSH and overclocked the controller. Then, I upgraded to 2.0.4 and I lost root access. The password no longer works. I upgraded to 2.0.5 and still get 'access denied'. Could the controller have been hacked somehow?

Hey, I had also a bad experience, ... but after using it with wiibox.net and setting all parameters and pool configuration over there it was fine ... I'm not sure but I guess that it does use some default configuration .. or maybe it has a trojan ... what ever I in the end just moved away from those controllers ...

ok, lol ... I got a f... problem ... somehow my controller is getting hijacked ...

... ... I haven't changed anything then upgrading to wiibox 2.0.2 ... that's it ...

user and psw is getting changed to ... a users miner ... called wwee.1, wwee.2 ...

... I already mentioned that on my controller .... that I received ... there was malicious code ...

that turned pool, user & worker .... to a thrid party in my absence ....

I haven't changed ... anything at the code, except upgrading with wiibox.net to 2.0.2 ...


Has someone a similar issue with a wiibox controller ?

my work around im not using that controller for the moment ...

[Pistachio]

Thanks, I will start working on a raspberry pi setup later this evening. Most of the setup guides I have read say 10 miners with a pi. Any tried a pi with say 40 miners?

It is doable, but you need to connect USB hubs in a certain way. You can only have 2 levels of hubs with the Pi, and 10-port hubs than come with the miners already have 2 levels inside them (6+4 ports typically). So you would lose 4 available ports if you daisy-chain those, and you need to connect to the correct ports on the first hub. Use "lsusb -t" to see the USB structure.

[richmke]

What raspi are you guys using?

Make sure you get "Model B" which has a LAN port.

Nope, fans are directly powered by +12VDC on the board. I unsoldered all of mine.

Thx for the great guide! Keep it on

AHA!!!!  That explains it then!  I have 40 miners and when I attached the 4 10-port hubs to a 7-port powered and then to the RaspPi it would only recognize 32 miners (10+10+6+6).  If I connected 3 hubs it would only see 26 (10+10+6).  So i'm guessing it was able to see a maximum of "levels" and after the first 2 10-port hubs are attached it only sees the first level of any additional hubs.

Do you know of any hubs that keep all the ports on a single level?  I already purchased and installed a 2nd RaspPi and have 20 miners on each, but in the future it might be helpful for others that want to control more from a single unit (which I bet it can since 20 miners only results in around 10% utilization).

My gridseed miner uses ST32 Virtual COM Port, and at the moment cgminer-3.7.2 doesn't detect the device. I've updated its driver by zadig, but still no luck. What is the solution to this?

Unplug the power from your hub, start cgminer, and plug the power back in your hub. I have 20 running in cgminer 3.7.2 and that is the only way to get the to work. Chang hotplug in your bat file to 5.

Also in your bat file to start cgminer set hotplug to 5 instead of zero, then with your gridseeds unplugged, run cgminer, after it has connected to pool plug your miners in and you are good to go

Probably too expensive but here is a 49 port designed for continuous enterprise use:

I just made an image, gridseed supported.
Just write image it to 4gb sdcard, stick it into your pi, fire up. Miners should start automatically after you've entered mining pool.
Hope this helps.

I am sorry, first upload was bad.....

Thanks to all from litecointalk, who made this possible.

Let me know if that works for you.

Thanks for posting that. Gotta pi coming Thursday.

One enclosure option

I crammed my 10 gridseeds into a PC mid-tower case like this -



Seemed like quite a lot of work though 

The 10 port hub I used was the cheapest I could find on ebay, ablout $6 (without power unit). I had a 5V 8A power unit laying about (bit of an overkill) so I used that to power the hub and raspberry. All seems to work well.

On the front I have just a mains on/off switch and one of the flap type cd blanking plates so that I can pull the flap down to get access to the raspi SD card if I need to.

I have two miners currently. Got them setup yesterday. Everything seemed to be going smoothly got them hashing in cgminer and left to work. When I got home I found that cgminer had crashed after maybe 2.5-3hrs of mining. Same thing happened overnight last night and then again this morning all within the same amount of time roughly. Any thoughts?

Edit: Thought I would add that the error wasn't very specific at all. Something along the lines of cgminer has stopped working click okay to close or something like that. Running windows 8.1 both are plugged into a hub.

[SummersideGuy]

Ok so I found a link to a youtube video and followed the video's instructions and I got my single red finned gridseed to  dual mine. So if you are like me and had the STM32 Virtual driver instead of the other one finish reading this and watch the video. Now the key is you have to remember the com assigned to the miner before you apply the usb driver with zadig as this is still secretly the com port to use in cpu miner

I have my red gridseed now dual mining in windows gets 330kh/s scrypt and 6GH/s sha256. I also posted a picture of it dual mining alongside a couple of  antminer U1's. To do this you have to have the antminers unplugged, and when you run cgminer for the gridseed have hotplug set to 0 so it does not try to detect the antminers and crash. then after you gridseed is all running launch bfgminer for the antminers.
