No Image works on ESP 32

[Damon3499]

Hello, I switched to Unbutu. Now I can build the image without any error. But the Images don‘t work on the esp. I tried almost every Board. It is rebooting all the time. I tried M5Stack Core 2, ESP32 dev kitv4, TTGo. What am I doing wrong? When I build the micropython repo everything is Fine. Could you please help me?

Please provide more information.

• Specify exactly how you built it
• Specify exactly on which board you are flashing the firmware
• Specify exactly what is displayed on UART before it's rebooting. Does it display some "Guru Meditation Error"? Backtrace?

I have Unbutu 22.04 installed.

I've downloaded this repo: git clone --recursive https://github.com/lvgl/lv_micropython.git I tried image on : ESP - WROOM 32 M5 Stack core 2 TTGO I do: /lv_micropython source tools/ci.sh && ci_esp32_idf44_setup throw an error -> tool Xtensa -esp32-elf does not have a version compatible with platform linux-arm64 (IDF version v4.4 -dev-3513-g142bb32c50) so I used the 5.0 version: /lv_micropython source tools/ci.sh && ciesp32 build throw an error -> Failed to resolve component "tcpip_adapter" so I used the 4.4 version: /lv_micropython source tools/ci.sh && ciesp32 build throw an error -> Failed ninja

I build the MicroPython Firmware out of the micropython repo and this worked when I mount the Firmware on the ESP WROOM 32 /micropython/ports/esp32 make erase /micropython/ make -C ports/esp32 BOARD=GENERIC deploy the build runs without any errors -> mount the image on esp - WROOM 32 no problem microphython v 1.19.1 is shown

if you need more info, please ask!

throw an error -> tool Xtensa -esp32-elf does not have a version compatible with platform linux-arm64

Are you building on arm host? I only tried building on x86 hosts.

Esp - WROOM32 BOARD=GENERIC_SPIRAM deploy

As far as I know WROOM32 don't have SPI ram. Why are you building GENERIC_SPIRAM board?

TTGO BOARD=GENERIC_SPIRAM deploy -> error on TTGO E(874) psram: PSRAM ID read error: 0xffffffff E(874) spiram: SPI RAM enabled but initialization failed. Bailing out.

Looks like your TTGO doesn't have SPI ram, so you can't use GENERIC_SPIRAM board.

-> error on M5 Stack Guru Meditation Error: Core 0' panic'ed (StoreProhibited). Exeption was unhandled. Backtrace: 0x4019e1cb:0x3ffd345b00x400d88b2:0x3ffd45e0 0x400d872d:0x3ffd4610

Please parse the backtrace.
To parse the backtrace you can pass the the hex values to xtensa-esp32-elf-addr2line:

xtensa-esp32-elf-addr2line -aipfC -e ./ports/esp32/<Board>/application.elf 0x... ... ..

Make sure you provide the correct ELF file under the right "\<Board>" directory.

Hello @Damon3499 , Please make sure to upload the correct firmware on device! So, SPIRAM supported firmware to device which has really external PSRAM (M5Core2 for example), and simple non-SPIRAM firmware to other devices (TTGO T-Display for example). See PSRAM for different ESP32 variants: https://en.wikipedia.org/wiki/ESP32#Surface-mount_module_boards

Basically, these 2 generic boards would fit for the 2 main cases (with and without PSRAM):

• GENERIC
• GENERIC_SPIRAM

I could build the M5CORE2 board successfully after a small fix (PR 56), and also checked GENERIC and GENERIC_SPIRAM build processes, they work.

As you tried to build the MicroPython firmware in linux-arm64 environment, and you received an error message, maybe you should check this page to install the correct tool: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/tools/idf-tools.html

If it helps, I can share my environment (and some help scripts), so you can have same, and maybe it will work or simplify some tasks:

• x86 (64 bit) Ubuntu 20 (running in Oracle VM VirtualBox)
• ESP-IDF 4.4.1 (tested with real M5Core2 device, it works with latest MicroPython 1.19)

Directory structure:

~
|- esp
|    |- esp-idf-4-3-3   (git: https://github.com/espressif/esp-idf/tree/v4.3.3)
|    |- esp-idf-4-4-1   (git: https://github.com/espressif/esp-idf/tree/v4.4.1)
|- src
|    |- build-lv_micropython
|    |- lv_micropython   (latest git master branch)

Help scripts: build-lv_micropython.zip

Extract it, and switch to it: cd ~/src/build-lv_micropython

Clean build folders: ./clean.sh

Erase device (set BOARD first in env-variables.sh): ./erase.sh

Build GENERIC-SPIRAM board: ./build-generic-spiram.sh

Deploy firmware to device (set BOARD first in env-variables.sh): ./deploy.sh

Monitor device output (install before picocom): ./monitor.sh

PS: in env-variables.sh script many ESP-IDF versions can be found, because previously only ESP-IDF 4.2.2 worked for me with MicroPython 1.18, but now MicroPython 1.19 works with ESP-IDF 4.4.1 also. You can clone other ESP-IDF versions also, which will work for you, and update env-variables.sh script to use that, if it helps.
