ESP32 builds fail when using display drivers SSD1306 or ST7789 #72205

Open zpm1066 opened 2 weeks ago

zpm1066 commented 2 weeks ago

Describe the bug Unable to build successfully ESP32-S3 firmware that uses Display Driver SSD1306 or ST7789. Previously, these built fine under Zephyr 3.6. The same code (with appropriate overlays) works fine for ARM boards.

To Reproduce Steps to reproduce the behavior:

  1. Build display driver sample for SSD1306 or ST7789
  2. Build fails.
  3. See error below in "Logs and consoles output"

Expected behavior Successful build.

Impact Showstopper for firmware that uses ESP32 with SSD1306/ST7789 displays.

Logs and console output Observe the following errors for several ESP32-S3 boards even though Display and SSD1306 drivers are enabled. The same configuration works fine with ARM boards.

warning: SSD1306 (defined at drivers/display/Kconfig.ssd1306:6) was assigned the value 'y' but got
the value 'n'. Check these unsatisfied dependencies: (DT_HAS_SOLOMON_SSD1306FB_ENABLED ||
DT_HAS_SINOWEALTH_SH1106_ENABLED) (=n). See
http://docs.zephyrproject.org/latest/kconfig.html#CONFIG_SSD1306 and/or look up SSD1306 in the
menuconfig/guiconfig interface. The Application Development Primer, Setting Configuration Values,
and Kconfig - Tips and Best Practices sections of the manual might be helpful too.

  No SOURCES given to Zephyr library: drivers__display

  Excluding target from build.

Environment:

Additional context The same code and configuration with ARM boards (tested using nRF52840, RP2040, STM42) builds & runs fine when used with SSD1306 or ST7789 displays.

ESP32-S3 boards with SSD1306 or ST7789 work fine with Zephyr 3.5.xx and also worked with initial 3.6.99.

zpm1066 commented 1 week ago

After observing the introduction of qualifiers "esp32s3/procpu" in Zephyr 3.6.xx, in build of xiao_esp32s3 board, I renamed the "xiao_esp32s3.overlay" to "xiao_esp32s3_procpu.overlay".

This has resolved the SSD1306 display devicetree issue but now throws the following errors when creating esp32s3 image.

The code with the same "xiao_esp32s3.overlay" builds & runs fine under Zephyr 3.5.x.

fgihl commented 1 week ago

Try adding --sysbuild to build command. That help me, when I had the same issue.

zpm1066 commented 1 week ago

@fgihl Thanks. Unfortunately, "--sybuild" didn't help. I tried a "git pull" and "west update", no change.

sylvioalves commented 1 week ago

@fgihl CAn you share both .conf and .overlay files?

fgihl commented 1 week ago

@sylvioalves

Will it help you if you looked at my sample program? west init -m git@github.com:fgihl/tenderizer.git --mr fgihl/esp32c3-sample west build -p -b esp32c3_devkitm tenderize

This compiles fine on Zephyr v3.6.0, but failes with Zephyr-main with the link error A fatal error occurred: Segment loaded at 0x3c0134b8 lands in same 64KB flash mapping as segment loaded at 0x3c010000. Can't generate binary. Suggest changing linker script or ELF to merge sections. ninja: build stopped: subcommand failed.

If I compile latest zephyr with the command west build -p -b esp32c3_devkitm --sysbuild tenderizer

With risk of hijacking the issue with other problems (Should I report this separately?) But when starting I get the following runtime errors: W (370) tsens: legacy driver is deprecated, please migrate to driver/temperature_sensor.h W (378) ADC: legacy driver is deprecated, please migrate to esp_adc/adc_oneshot.h And neither ADC or internal tempsensor works.

Here are the configuration and overlay being used with target xiao_esp3s3 and Zephyr 3.6.99. The same configuration/overlay work fine with Zephyr 3.5. Also worked fine with Zephyr 3.6.0.

There are no compilation errors and the SSD1306 OLED works as expected.
