Lucky Miner LV07 - Firmware wanted

[unpainted]

…

I have already placed buttons at the ends of the drop-down lists for both frequency and core voltage, I just haven't been able to work out the code that goes along with a mouse click. My question is, do you know how to do this?

Any help would be appreciated...

Have a look at

main/http_server/axe-os/src/app/components/settings/settings.component.ts
updateSystem() on Line 105

main/http_server/axe-os/src/app/components/edit/edit.component.html
Line 93

main/http_server/axe-os/src/app/services/system.service.ts
Line 81


I have never looked into saving the settings and don't understand everything straight away.
Good luck!

Yes, I've already looked at all of that code. That code does a complete save of all the settings even if only one thing was changed.

It shouldn't be anymore than just a few lines of code to send a button click to the ESP32 to say update the core voltage from the drop-down list and do nothing else.

Anyway, thanks for getting back to me so quickly, I appreciate it.

FIRMWARE UPDATE
The latest update v2.8.1 is also available from me for the LV07: https://github.com/un-painted-org/ESP-Miner/releases/tag/v2.8.1-LV07

Have fun with it!

can someone please help me I need the original lv07 firnware 1.0.0 or 1.1.0 mine is bricked after trying opensource firmware. Did try all I could find but no luck,

[Viper305]

Just got my first LV7 and noticed it has a Firmware 1.2.0 unlike the ones you are all talking about having 1.0.0 and 1.1.0.
I was wondering if it would be safe to flash using the Web OS?

Any recommendations?

Can this be Flashed through Web Page directly on a Brand New LV07??

No concerns. As far as I know, the LV07s are all identical.

Not at the moment, v2.6.0 is currently available in the webflasher. An OTA update to v2.8.1 is then possible in the AxeOS settings.

[Viper305]

Thanks for everything.  Backed up and Flashed to Latest!!!

I tried to update the firmware of LV07. I did what it says to do, but it seems to be a situation where there is no screen and only the fan is running. I tried to update the firmware again, starting from scratch, but nothing happened. I want to fix this problem, please help.

That is what is supposed to happen.  The Miners Screen goes black and the fan goes full Blast.  That is what it does when its ready to be flashed.  At that point hit connect or flash and let it complete 100%.  

When finished unplug Jtag and Reset the Miner.  The Screen will come back to life.

Just updated the web flasher to v2.8.1-LV07: https://un-painted-org.github.io/bitaxe-web-flasher/

EDIT:

https://tooomm.github.io/github-release-stats/?username=un-painted-org&repository=ESP-Miner
Over 2,300 downloads in total on GitHub alone, not counting web flashers. Nice to be able to help so many people! 
The fact that none of the estimated 1,000 souls thought to donate shows the challenges that come with free open source software.

Hi. Could you make a video tutorial on reflashing. What program and what programmer do you use. And also in more detail how and where to connect the wires. I'm sure you would have many more fans and views on YouTube.

Hello unpainted.

Are you familiar with using a jTAG device with a 6 pin probe attached?
If so, I can send you a copy of my LV07 v1.0.0 backup factory firmware and you can flash your LV07 back to life with the jTAG and probe.
If you take off one of the metal panels on the LV07, it's the one on the left if you're looking directly at the LCD screen, you'll see the jTAG probe points.
I bought both the jTAG and 6 pin probe from AliExpress.

I did the same thing as you and tested several other firmwares on the LV07. But because I learned how to flash my Bitaxe MAX (which has no USB port) and LV06 using the jTAG, I was able to revive them! Luckily I had 2 other LV07 miners and I saved a copy from one of them and flashed it back to the non working one without any problems. The only mistake I made, was not making a backup of my LV07 first before I flashed it as it was my newest LV07 with the newer 1.1.0 firmware!

Hey, I'm looking for the original firmware for LV07, it could be version 1.0.0 or 1.1.0, can you get it for me? Thanks.

This is an interesting thing that happened to me.

I have three LV07s. I successfully installed AxeOS on them, and everything works on two of them.
On the third, the ASIC chips aren't being identified: ASIC STATUS: Chip count 0

What I did was remove the heatsink, and now the chips are identified, but I have a problem with the TPS546:
TPS546: Status: 0x4851
TPS546: The voltage regulator is turned off
TPS546: An output overcurrent fault has occurred
TPS546: TPS546 IOUT Status: A0
TPS546: IOUT Overcurrent Fault
TPS546: IOUT Overcurrent Warning
TPS546: The output voltage is NOT within the regulation window. PGOOD pin is asserted.

I believe it's due to excessive power consumption on one of the chips.

I didn't test this LV07 with the original firmware; I flashed it immediately.

Do you think it could be something with the firmware or hardware?

Thanks.

After trying various approaches, it seems I've bricked my LV07 due to seeing the following in my serial console:

Code:

I (9874) self_test: 2 chips detected, 2 expected
E (9880) i2c.master: I2C transaction unexpected nack detected
E (9885) i2c.master: s_i2c_synchronous_transaction(945): I2C transaction failed

E (9970) vcore: VCORE_set_voltage(141): TPS546 set voltage failed!
I (9976) self_test: SELF-TEST FAIL -- Press RESET button to restart.

I then put the unit into flashing mode by grounding the IO pin & pressing the reset button, which returns:

Code:

I (9983) bm1366: Setting max baud of 1000000
I (10000) serial: Changing UART baud to 1000000
ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x1 (POWERON),boot:0x20 (DOWNLOAD(USB/UART0))
waiting for download

I've had very limited success with flashing my LV07 & have noticed a few 'Self-test: Fail' messages that only adds to my thinking the LV07 is bricked.

However, there is one firmware that seems to consistently work (inasmuch as the LV07 isn't acting dead i.e. black screen) when powered up after flashing using https://github.com/un-painted/ESP-Miner-TCH/releases & the bitaxetool command:

Code:

bitaxetool -p COM7 -c config-lv07.cvs -f esp-miner-merged.bin

Fortunately, the above at least allows the LV07 to boot & display meaningful feedback on its screen. Also, having configured the 'config-lv07.cvs' file with my own wifi settings, I can also reach its web page showing 0 hashing rate, intermittent temperatures & voltages = not good!

I'm therefore getting to the point where I'm thinking that I may have indeed bricked my LV07. I'm a little surprised if this is the case, since I've only soldered on a small header to the JTAG pcb holes so I connect to my CP2104 UART to USB Adapter (which is working fine) & followed numerous tutorials & approaches (from here & youtube).

I'm now wondering if the original firmware might bring it back to life? Like others, I've been struggling to find the original firmware but am hoping someone might have a copy & am wondering if you'd be so kind to let me know if I can get a copy, or perhaps let me know of another source?

I'd love to get my LV07 back working again & would really appreciate any help.

Cheers!

As per my previous post above, I reached out to Lucky Miner to request a copy of the LV07 firmware but they just replied that I should buy another one, so I did.

I found a cheap new LV07 on AliExpress, which arrived 6 days later.

Connected the CP2104 UART to USB adapter & successfully downloaded the firmware.

Then uploaded to the older LV07, which at first seemed to spring into life. The display showed the expected screen, but I couldn't connect to it over its internal WiFi.

I'm still seeing various errors in the serial log, so am guessing I must've damaged something during my firmware update efforts...

Code:

E (2965) i2c.master: I2C transaction unexpected nack detected
E (2965) i2c.master: s_i2c_synchronous_transaction(872): I2C transaction failed

I'm therefore kinda wary of giving it another go on my new LV07, as I don't want to repeat the same mistakes.

Having read through this larger thread it seems some folk have had success, so I'm wondering if there's any pointers/tips you might be able to give?

Cheers!
