Flash Problem Lolin ESP32 Board

#1 Post by dnwalker » 06 May 2020, 17:46

Hi,

I have been trying to flash a Lolin32 V1.0.0 board for some time.
The version ESPEasy32_R20100.bin works without problems on the Lolin32. I copied the version to the Lolin with flashSerial.bat.
Now I tried to copy the version ESP_Easy_mega-20200426_custom_ESP32_4M316k.bin with the new ESP.Easy.Flasher onto the board. Unfortunately the flash tool doesn't work for me. The log file says the following.
#############################
[2020-05-06 17:25:13] The COM port was already in use ... the post-flash did not complete.
[2020-05-06 17:25:13] JOB COMPLETED, over and out!

Since I absolutely cannot get the tool to run, I wanted to copy the firmware to the board with the flash_download_tool_v3.8.5.
Can someone tell me how to set the tool? So far my attempts have been unsuccessful. I'm unfortunately a beginner in this area.

Greetings dnwalker

Esp Easy Flasher isn't working for ESP32. I will make a new flasher once I get the time. Sorry for the inconveniences.

That's the 4th or 5th post I see today describing this ancient ESP32 build.
Is there a recent blog post writing about it?

See my post here for links to a recent build I made for flashing ESP32: https://www.letscontrolit.com/forum/vie ... 622#p44622

Well, it is listed on the official Wiki page on ESPEasy32:
https://www.letscontrolit.com/wiki/index.php/ESPEasy32
bottom of the page shows a link to the original download location.

The zip file also includes a working flash tool. Don't know why al these people have issues with ESP32. I never had any issue with any build on several ESP32 modules. I use the serial tool for the first load, then the ota tool for updates

Maybe it's time to update (at least some of the) wiki pages??
You may also consider to remove all links to R120, also from sourceforge and nominate a more recent mega build as
"stable"

Well it was more striking to see in the last few days a number of references to exactly the same issue, using the same older ESP32 binary you once made.
Usually there is only one reference to that ESP32 build every month or less.

And indeed I am now quite convinced we regained stable builds again, so just a few more tests and then we declare it stable and update the links etc.

By the way, I don't think we have access to the Sourceforge pages.

I'll email the account information to you, so you can add the 'long-awaited' new stable. 8-)
SourceForge
I'm currently using 20200410 as base for my own customized edition and it looks solid to me.
