Re: Brown Out Detector Bug/issue
Thanks for the update and the detailed scope shots, etc. I think this is probably a hardware fault with the DOIT board not integrating enough capacitance on the board. The fact you can see a pulse down to 2.6V on what looks like a fairly slow scope trace makes me think it probably is dipping lower ...

Re: Brown Out Detector Bug/issue
Hi Angus, I update ESP-IDF to new "3.0 pre-release rc1" and got new informations about BOD. 1-) Before the update, when it was with 1mF capacitor it continued to reset, however now with capacitor does not reset. 2-) Without the capacitor, reset. 3-) Note: This did not happen in the past, it only sta...

Re: ESP32 Automatic flash error
I was testing some items in ESP32 that have this automatic flash problem and I noticed something very strange!
When I use "make erase_flash" and then I upload any sketch "make flash", it works most of the time, not requiring capacitors or pressing the button.
What is it? What is going on? Solution?

Brown Out Detector Bug/issue
Since yesterday the BOD of my esp32 is crazy, restarting randomly (apparently) when starting the WiFi. Sometimes when I set the BOD to 2.6V, the ESP32 keeps restarting endlessly (but sometimes it restarts 5-10x and stops), however, when I change to 2.1V and return to 2.6V, it stops !!!! (sometimes t...

Re: ESP32 Automatic flash error
I added a capacitor as mentioned in a post (https://github.com/espressif/esptool/issues/136) and it worked.
So I already have two ways to make it work: pressing the button or adding a capacitor between EN and GND.
But is there no way to set the times between DTR and RTS to "get around" this bug?

Re: ESP32 Automatic flash error
I have tested the commands by ESPTOOL.PY itself and all commands are working (activating and deactivating the pins as programmed). I tried several delays and ways to make it work, but the boot just does not happen. However if done manually it happens. I think I need to go to the oscilloscope, but wi...

Re: ESP32 Automatic flash error
I'm not familiar with your board, but if it's like the Espressif ESP32 Core Board, the auto-programming is handled by two transistors hooked to the RTS and DTR lines of the onboard USB to serial bridge IC. Have you verified that the DTR and RTS lines are toggling when you attempt to flash? If not i...

Re: ESP32 Automatic flash error
The procedure to enter the bootloader mode is quite simple: press and hold the BOOT button press and release the EN button release the BOOT button. Flash your firmware. You don't need to change anything. I know about this, but the question is "why automatic doens't work?" My last nodemcu trigger DT...

Re: ESP32 Automatic flash error
Sorry, I forget. It's NodeMCU-32 DoIT, see photo:ESP_Sprite wrote:What board do you use? You're talking about an ESP32 but that is only the chip.
(both can't flash without press button)
