I think most people SSH into the Pi from their computer, rather than attaching a monitor/keyboard.
Where can I find instructions on how to do that? I'm completely new to Linux.

Anyone try out the CuBox-i? Comes with Ubuntu (and android). Do you think I could compile from cgminer from github on it? It's ARM based like the Pi.

Any advice on a screen to use with raspberry pi?
It has an HDMI port. Anything with an HDMI port (like your TV) should be fine.

Has anyone tried a large amount of gridseeds on cgminer? I am trying 28 of them on a rasberry pi and it stops accepting shares and eventually crashes after about 2 minutes. Running 28 instances of cpuminer works great, stable, and multipool reports right about where the hash rate should be.
Mine's been stable since upgrading to the "next" kernel (3.10.30+):
sudo apt-get install rpi-update
sudo BRANCH=next rpi-update

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.

What's the root PW? It's refusing SSH connections too...
got in on the web interface with default pw scripta, forgot about NoScript stopping me...lol
Still refusing SSH, however...
SSH is on port 7722. Root password "scripta".
Ah, perfect. Thanks!

What screen / external monitor would you guys recommend to use with a Raspberry Pi?
March 12, 2014, 10:42:41 PM
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, ®_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, ®_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.
Did someone find a measurement point on the board to check? What happens if we pass -1? I'm surprised more people aren't asking about this, surely with as much cooling as these chips have on them we can get away with a bit more voltage in scrypt only mode, and hence, higher stable clocks! I don't want to sacrifice a miner if I can avoid it by researching instead...
Yes, it should be possible to replace a resistor to increase the voltage. I haven't had a chance to try this yet.
OK, that's pretty clever.

Sorry for cross posting but....
Somethings not right,
First I'm trying to use Scrypt guild.
without the --scrypt in the command line it does not recognize the shares
Then when I have 30 Gridseeds going it never sees more than 5Mh when I think I am sending 10Mh
Using this command line:
Bfgminer -S gridseed:all --set-device gridseed:clock=850 --scrypt -o stratum+tcp://stratum.scryptguild.com:3333 -u joeventura123 -p anything
again note without the --scrypt it does not see a single share.
Ideas?
Anyone know where I can find cgminer windows binary that works with gridseeds? (5 chip)

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).

-Eric
Probably too expensive but here is a 49 port designed for continuous enterprise use:
How about 2 of these?: http://www.monoprice.com/Product?c_id=103&cp_id=10307&cs_id=1030702&p_id=6436&seq=1&format=2
One for each of the Raspberry Pi's 2 ports? We should be able to conceivably connect up to 48 miners per RPi... Anyone had any experience with these or know its internal topology?
-Eric
Monoprice 24-port hub has 7 ports at the first level, 3 of those connect to 3 internal 7-port hubs. The total comes to 25 ports (4 remaining at the first level, + 3*7 at the second level), not sure where the 25th port is though. Anyway, good news is that Raspberry Pi can access all 24 ports. I have not connected miners to it yet, but tested with a USB flash drive. Will follow up once I do a real mining test.
