ESP32 PICO D4 arduino ide support

[fedy0]

How do I program esp32 PICO d4 in arduino ide? (there's no board variant based on it included yet)

[lbernstone]

PICO KIT looks like it is just a standard ESP32 dev module.

[fedy0]

Actually, I'm using TTGOV2 board ( https://github.com/LilyGO/TTGO-LORA32-V2.0) which uses esp32 PICO d4.

I have tried to upload with all board variants of esp32 in arduino ide but failed.

OS: Windows 10
IDE: Arduino 1.6.9
arduino-esp32 (core) : latest version
Board: TTGOV2
Error during upload:
"... Warning: Could not auto-detect flash size (FlashID=0xffffff, SizeID=0XffA, defaulting to 4m

fatal error occurred : Unknown size 4m"

Any help would be greatly appreciated

Update Arduino to the current version 1.8.5

[copercini]

it was committed few hours ago: d29cfdb

[fedy0]

I saw it and I just updated and tested now. It uploaded completely (using "esp32 PICO kit" option) but it was continuously restarting the MCU

[copercini]

any error or message in the serial?

[fedy0]

None, just after the display of boot messages on the serial monitor it restarts

I'm able to upload the Sketch to my ESP32_PICO_kit_v4. Since in Arduino v1.8.3 there is no board variant for ESP32_PICO I have tried with board configuration of ESP32 Dev Module (ESP-WROOM-32).
Upload was successfull, but SW is not running. Now I try with Arduino v1.8.5 ....

@tolo69 what sketch did you try to run? Try something simple first, like sending a message over Serial every 10 seconds.

[tolo69]

Thanks for the hint ! Now my simple Sketch for the PICO_kit_v4 runs - just toggling IO15 and cyclic sending a string to COM-port.
used configuration: Arduino-IDE v1.8.5, board: ESP32 Dev Module.

@tolo69 @copercini @Ibernstone @beegee-tokyo @stickbreaker

Mine is not working. I am using TTGOV2 LoRa32 based on esp32 PICO d4 with arduino 1.8.5. I selected both "ESP32_PICO_kit" and "esp32 dev module" in Arduino board options but after upload it could not run... Always restarting and printing unrecognized characters in the serial monitor.

Please anybody successful using this board (https://github.com/LilyGO/TTGO-LORA32-V2.0) on arduino ide, help me?

[tolo69]

which URL-path for ESP32 board configuration have you included in the IDE-Settings ?

[fedy0]

I cloned the repo (https://github.com/espressif/arduino-esp32/) into my Arduino ide folders (C:/arduino-1.8.5/hardware/)

It's up to date with this repo.

Are you using the same TTGOV2 board? @tolo69

Please comment @Ibernstone if any suggestion

[beegee-tokyo]

@fedy0 I found this article I guess it is the board you have. In the article they say download the TTGO folder and copy it into <Sketchbook Folder>/hardware or Arduino/hardware Unfortunately the link goes to a Chinese Baidu post and to download the zip you need an account on Baidu. But maybe you can find TTGO WIFI-OLED.zip somewhere else.

I'm using same URL for board config but HW ist ESP32_PICO_kit_v4.
