Having trouble flashing and running bitaxe-raw

[jayrmotta]

Hi!

It's my second time flashing bitaxe-raw, the first time I had an issue with the app descriptor not found running the main branch but an LLM helped me workaround it by creating a C file and making some changes to the code which I unfortunately discarded. That version is working well on my first BitAxe, but I got a new BitAxe and I can't get it to work with bitaxe-raw.

I'm running branch esp-hal-update which doesn't fail with the app descriptor missing.

Tooling

cargo & rustc 1.92.0-nightly
espflash 4.3.0

Flashing

▪ cargo espflash flash --release --chip esp32s3

Then I check the serial ports, press and release RESET on the BitAxe:

▪ ls /dev/ttyACM* 2>/dev/null
/dev/ttyACM0
▪ ls /dev/ttyACM* 2>/dev/null
/dev/ttyACM0  /dev/ttyACM1

Looks promising, proceed to run Mujina:

A different error on the second execution. In some of my attempts with different branches, downgraded espflash, cargo flash, and trying to manually introduce the app descriptor on the main branch, it resulted in failure to flash due to app descriptor missing or it succeeded and resulted in the errors above. In one attempt I also saw a "packet too large" along the "control stream closed".

If anyone knows a deterministic path to building and flashing this so I can run Mujina with the BitAxe please share.

[skot]

It seems like everything is working well up until the point mujina enables the Bitaxe TPS546 voltage regulator. @rkuester any ideas?

[skot]

I see from your comments in 256foundation/mujina#33 that everything was working on the first Bitaxe, but this problem seems unique to the second Bitaxe? That suggests a HW issue with the second Bitaxe. Is there any difference in the hardware between the two Bitaxe? Are they both Bitaxe Gamma 601?

The first is a 601 and the second is a 602.

A few minutes ago I just flashed the SV2 branch of ESP-miner I've been playing with onto the 602 and it worked fine, so that should discard the HW issue hypothesis. Then I flashed bitaxe-raw again, ran mujina and got to the same errors described in the issue.

[skot]

I wonder if there is a change from 601 -> 602 that is not reflected in Mujina (but is in esp-miner). I'll take a look at the changes

[skot]

I don't see any hardware changes from 601 -> 602 that should require any firmware changes.

I did see some errors like your log shows when using my Bitaxe 601 running bitaxe-raw with Mujina. It seems like the Mujina control serial buffer was somehow out of sync with the Bitaxe. I was going to look into it more, but when I restarted by bitaxe and Mujina, the problem went away 😳

[jayrmotta]

Earlier today I had a session with @majoal0 and we sucessfully flashed his 602 then ran Mujina as expected. Also heard from @johnnyasantoss the same, I believe his might be a 601.

I honestly have no clue why it doesn't work on this new 602 I got, since it seems to run ESP-miner normally then I'm running out of clues. I will continue to experiment and see if I can figure what's wrong.

[rkuester]

The first log seems to show I2C IO failing and perhaps even USB IO failing¹ right after regulator output powering the ASIC was turned on. The second log shows I2C not working right from the start.

I wondered if this was some kind of brownout or other hardware issue when turning the regulator on, but if the board is working with esp-miner, it must not that simple.

It's worth pointing out that restarting Mujina doesn't take the entire system back to square one. The Bitaxe's microcontroller running bitaxe-raw remains powered on and not reset, and the peripherals like the regulator remain powered on and thus maintain some state too. Perhaps Mujina could and should do more to reset the Bitaxe, but for now, assume it's not doing much. If you really want a clean second run, at least reset the Bitaxe with its pushbutton, and perhaps even cycle its power to reset the regulator.

Is this a mainline build of Mujina or a Mujina with your local modifications, @jayrmotta?

I'm at a bit of a loss at the moment too.

Footnotes

1. See the "Control stream closed" message, although that might be secondary; e.g., a race during the teardown after the board failed to initialize. ↩

If you really want a clean second run, at least reset the Bitaxe with its pushbutton, and perhaps even cycle its power to reset the regulator.

I recommend doing a hard power cycle by pulling the plug. The reset button just resets the ESP32 and won't necessarily reset state in the voltage regulator, especially if you are running bitaxe-raw

[jayrmotta]

Well, I'm happy to informe the problem is gone, just don't ask me how. At some point I flashed the 602 again and it simply worked.

I won't dare speculating why yet, but I'll keep an eye 👀
