Bootloop with TTGO LoRa32 V2.1.6 board with platform-espressif32 v4.30 and higher

[hekopath]

Update: See further below for a more complete description of the workaround.

---

I have observed a bootloop after using the latest espressif32 plattform with a ttgo_lora32_v21 board.
My personal workaround was to specify the previous version in the env section for my board variant.

[env:ttgo_lora32_v21]
platform = espressif32@4.2.0

Can anybody confirm this problem?

Tested with the current main branch (v.1.3.0 version fail to build because of #41 )

Thanks for your workaround - i have the same board and get the same issue with latest espressif32.

I tried to reproduce the issue with both the TTGO LoRa32 V2.0 and TTGO T-Beam V0.5 boards and both worked fine, without showing the issue. I only have the V2.0 of this board and none of the V2.1.x versions.

For the test I upgraded all platforms and libraries (pio pkg update). Platform Espressif32 was then updated from v4.2.0 to v5.0.0.
I then removed (delete) the platform Epressif32 installation to start with a 'clean' situation.
I replaced all platform=espressif32 instances in platformio.ini with platform=espressif32@4.3.0, selected board-id ttgo_lora32_v2 and then pressed 'Upload'.

This initiated install of the Espressif32 v4.3.0 platform.
The build and upload both succeeded and I was able to run LMIC-node using Espressif32 v4.3.0 on both the TTGO LoRa32 V2.0 and TTGO T-Beam V0.5.

Below output for the TTGO LoRa32 V2.0 while using Espressif32 v4.3.0:

So is this bootloop issue with Espressif32 v4.3.0 specifically related to the TTGO LoRa32 V2.1.6 board or could there be other reasons that caused the issue for you?

By the way, Espressif32 v5.0.0 is already available. Are you still experiencing the same bootloop issue with v5.0.0?
Don't forget to replace any platform=espressif32@4.2.0 instances in platformio.ini with platform=espressif32 again before testing.

[damanti-me]

thank you for your time and investigation.
I repeated the process with different versions of Espressif32 library. For both (v5.0.0, v4.4.0 and v4.3.0) i get the bootloop. And 4.2.0 is working for me. So it seems to be related to Espressif32 lib. If you tell me other ways to verify im would be glad to help.

To not alter the environment to much i just upgraded within PlatformIo

The base of this test is still the main banch from 26th May.
Only modified the lorawan-keys.h

I can conclude the bootloop situation persists.

[lnlp]

@damanti-me

If you tell me other ways to verify im would be glad to help.

Thanks. To start, providing logging as shown above for each of the tested configurations will be useful.

When exactly does the bootloop occur? Based on @hekopath's log above the upload appears to succeed after which the device is automatically reset and then right at the first run the boot loop starts. Is that correct?

Only modified the lorawan-keys.h
And now with removed @4.2.0 Tag

The following is remarkable:

Above build log shows espressif32@4.2.0 and PLATFORM: Espressif 32 (4.2.0) instead of PLATFORM: Espressif 32 (5.0.0).
So either the build log you showed is incorrect (from a different build session) or the @4.2.0 part was not removed everywhere in platformio.ini. If latter then the code should run and not boot loop which your run logs currently shows.

---

How come your build log shows PLATFORM: Espressif 32 (4.2.0) instead of PLATFORM: Espressif 32 (5.0.0)?
Is the log incorrect or is there something wrong with your PlatformIO configuration?

[lnlp]

Which operating system and version are you using?

[TD-er]

Also keep an eye on the used esptool and elf2bin versions.

The newer version (4.x) does call elf2bin with parameters to append an SHA checksum of the binary.
But if it was already "signed" with such a checksum, it will not patch the binary when flashing to set the correct flash size and flash clock frequency.
Simply because changing these bits will corrupt the checksum.

The 4.x version of esptool does check for this, but if the bin was made including the SHA and esptool doesn't check for it, it may corrupt the bin while flashing.
On the other hand, if the wrong flash parameters were set in the board definition or PIO env, then esptool cannot correct for it when flashing.

[lnlp]

Thanks.

So to my understanding: After updating the ESP32 platform version in PlatformIO it will be best to delete the .pio/build folder to remove the binary to prevent any possible issue with what you desribed?

[TD-er]

And also make sure esptool is not mentioned with a specific (different) version in the requirements.txt for the Python virtual env.
