OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

Hi! I search for report a issue in github, but no clue
cgminer crash, when ID from ASIC reach to 32535, terminal get with chars from last update, and cant see any command in terminal....
the final log line is: "hotplug thread 32535 create failed"

[vested]

Ive been getting "cgminer: --scrypt: unrecognized option" when trying to run my batch file on cgmine 4.5.0

Any known reason for this?

Thanks

Scrypt mining was removed and is no longer available in any versions newer than 3.7.2.

It looks like it's hitting a thread count limit on your operating system, and that's not surprising, but the real question is why do you even get to IDs that high? If you have massive instability that leads to devices constantly dropping out and being re-hotplugged then you have some other major problem.

Hi ckolivas & Kano,

I noticed Bitmain have uploaded their cgminer source code here:

https://github.com/bitmaintech/cgminer

Did you guys get a chance to check it out yet?

Peace

We've not I'm afraid as we've both been busy with this upcoming pool project that is no longer a secret. Kudos to bitmain for finally releasing the code, and even better that they synced up with latest cgminer. However from my understanding the S3 code rips out and replaces the S1 and S2 code so it will almost certainly need massaging just to make sure it's not stepping on other drivers even before we can start talking about improvements. Hopefully soon...

Thanks, havent mined in a while, haha.

Turns out it's the USB cgminer, not the Ants.....

They've said they'll release a new firmware version for the S2 & S3 units soon....

Peace

Is the --enable-ants1 for cross compiling for OpenWrt to run directly on the S1??

I've tried the master branch, bitmain repo and kanoi repo and none detect the actual blades on OpenWrt on the S1 controller...

Now to search for an older version and give that a go.

Edit:

Used the ants1-4.3.2a-85fcf0c branch from kanoi's repo and that works,

Get this once in a while?

A quick question for ckolivas or kano...

A while back I started looking at cgminer with a view to making a few minor modifications.  It took a while to get my head around how the software worked but I really couldn't find an important bit of code, i.e. the code that actually calculates the final hash value.  Obviously sha2.c contains the sha256 code but it is the part that calls it to generate the final hash I am looking for.  After the Merkle root etc. have been calculated the hash routine should be called 3 times, twice for the first hash due to the length being 80 and then once with the resulting 32 byte result to give the final result.  I can see that the first part of the first hash only needs to be calculated once as the nonce changes as that is beyond the first 64 bytes and this appears to be then stored in midstate but I can't see where that is then used with the nonce to finish the first hash and then do the second hash to get the result.

Also, is regen_hash only used once a result within difficulty is found to double check the result?

It's a while since I last looked at the code but I'm sure you understand what I mean and hopefully can point me in the right direction.

New release: Version 4.6.0, 7th September 2014

As the sun sets on the home mining scene, here's a new release mainly with the driver for the BFL mofarch that was completed months ago but sitting around waiting for someone to actually take delivery of them. I'd been holding off till now because they promised a new firmware and I was going to redesign the driver around it, but that never eventuated...


Human readable changelog:

- BFLSC28, aka BFL Monarch driver.
- Avalon2 driver updates.
- Minion driver updates.
- Allow passwordless workers now.
- Disconnect connections to unused stratum pools more reliably.


Full changelog:

- We should not be checking for pool_unworkable in cnx_needed as it is keeping
stratum connections open on unused pools
- Properly handle lack of input when adding pool via menu
- Allow workers without passwords
- minion - increase max chip number
- Avalon2: add more comments on Avalon2 options
- Avalon2: add polling delay option, long coinbase support, LED status on API,
change overheat from 88 to 98
- minion - add a ' before non-zero core error counts
- minion - hidden optional per core nonce stats
- bflsc28 - clock is hex
- bflsc28 - allow setting clock and volt from the API ascset command
- bflsc28 - add chip count to stats
- bflsc28 stats
- Simplehacks to better serve bflsc28
- Only use one hashtable for bflsc28 work queued
- Copy back the buffer after we've stripped the inprocess field on bflsc
- Parse results for BMA based on uid and remove work from the queue when found
- Strip out the inprocess details from bflsc results if it exists
- Create a hashtable of work by uid as it's accepted by BMA
- Add some rudimentary values for BMA sleep times
- Fix various errors in queueing work for bflsc28 and limit job queueing to 10
to fit within a usb frame
- Create preliminary work queueing for bflsc28 using jobs of up to 20 at a time
by rolling work where possible
- Convert all bflsc transfers to the full 512 bytes
- Don't mistake bflsc28 for fpga
- Do initial detection of bflsc28 devices

No 4.6.0 Windows executable?

So true. The peoples coin - taken from the people......

Thanks, works.

Regarding the S3.

I don't have the build environment to create a full binary image, and the code will need a LOT of work to actually become part of mainline cgminer it seems, but for the time being here is a link to a bugfixed binary of cgminer 4.6.0 for the S3 based on the bitmain code. Copy the file into /usr/bin/ on the S3 overwriting the existing one:

Thank You for the fix. Processor load is way down. It is really great to get this working even better. Hopefully both of mine can now handle 218 not one 218 and one 212.

Hi,

I see these messages when cgminer works, but can't find any documentation regarding them. What do they mean?

They didn't come one after another, I only collected the messages I don't understand. Here we go:

BFL looking for BFL 0403:6014 but found 1002:4396 instead

Not a ZTEX device 1002:4397
 and later: USB scan devices: checking for BAS devices

AVA looking for AVA 0403:6001 but found 148f:5370 instead

ICA looking for BLT 0403:6001 but found 148f:5370 instead

GPU 2 found something? OCL, NONCE 8.... found in slot 0

Generated stratum header 000....

Generated stratum work

I'd be grateful for any help.

I'm not sure where you're seeing these messages. There hasn't been any GPU code in mainline cgminer for over a year and I'm not supporting anything but the current version.

Thanks @ckolivas.

This is the output of cgminer.

I use it to mine on testnet. There are 4 radeon 79xx gpu cards, and according to cgminer stats it does ~2.5gh/s - I was hoping to mine something, especially that current testnet difficulty == 1.0, but it doesn't work, hence I posted this warning(?) messages.
