Could you make an option to not disable the SHA cores? That way we could run this version for Scrypt and the other version that supports SHA concurrently.

I get the error

driver-gridseed.c:543:3: error: non-void function 'gridseed_pl2303_init' should return a value [-Wreturn-type]

I also get quite a lot of warnings like ...

driver-gridseed.c:383:22: warning: passing 'unsigned char *' to parameter of type 'const char *' converts between pointers to integer types with different sign [-Wpointer-sign]
        else if (strcasecmp(p, "per_chip_stats")==0) {

Have you seen anyone get this working on OSX yet? Ill happily be your guinea pig

(Thanks for the OSX fix!)

When I startup cgminer, I get the message above. I am trying to start it with

./cgminer -o stratum+tcp://doge.us.1coinpool.com:3334 -u xxxxx -p xxxxx --scrypt

Sorry for posting a question here, but perhaps you can redirect me to your email or a forum on which you're available to answer questions like this. thanks.

Here's my question:
The GC3355 datasheet (from one of your repositories) states:
"GC3355 is easy to program to support UART speed from 9600bps to 6.25Mbps and the typical baud rate is 115200bps."
I'm currently using a baud rate of 8 X the typical (921600) without too much of a problem. How high can I push this and is there any need for me to push this? Is there a harmful affect to the chips an/or will it up the hardware error rate?

I'm currently using an ACER netbook running Ubuntu 13.04 to control 4 Gridseeds (5-chip) units in a multi-pool balance strategy.

Thanks in advance,
Mxb

I tried adding freq to the config file but cgminer didn't start with the clock speed I set "850". Also, adding hotplug didn't work either. It seems cgminer is ignoring these.

As shown here http://cryptomining-blog.com/1893-performance-results-of-the-new-gridseed-blade-miner-asic/ the local hashrate doesn't get displayed correctly in the screen session.

Can you add support to show correct hash rate for these units?

I'm running this on a raspberry pi Model B, with 2014-01-07-wheezy-raspbian.

After first boot and running the pi config I proceed to install cgminer-gc3355:

sudo apt-get update
sudo apt-get install libudev-dev libcurl4-openssl-dev
git clone github.com/dtbartle/cgminer-gc3355.git cgminer
cd cgminer
./configure --enable-scrypt --enable-gridseed
make && make install

The make/make install does output some errors:

The make completes so I start cgminer:

sudo ./cgminer/cgminer --scrypt -o stratum+tcp://stratum-us.anc.hashfaster.com:3337 -u xxxxx.xx -p xx -T

But it hangs after the last line of output here:

Blocks are generated and sent to pool (and being accepted by pool)
Connection to pool is lost
Reconnect succeeds (acording to displayed message)
But no more blocks are sent to pool

Any updates to the 3.7.2 code to allow API concats? (Example: {"command":"summary+dev"}) This works on newer cgminers.

With 20 Gridseed G-Blades hooked to cgminer running at 838Mhz I am getting an error in cgminer after about 15-20 min of running.

Cgminer says: tailsprintf buffer overflow in driver-gridseed.c gridseed_get_statline line 813

Cgminer then freezes and you have to kill the session and start a new one.

Stop cgminer (q)
restart cgminer
no gridseed device is found
unplug/re-plug gridseed device
restart cgminer and device is found

when i start the miner all it does is read me my mining settings over and over or it says that my pool requests a work restart
