PROBLEM DESCRIPTION
Since updating to platform-espressif32@55.03.36, the display is constantly blinking/flashing on M5Stack devices. The same code works perfectly fine with platform-espressif32@55.03.35.
I am creating this issue on this repo as recommended by @me-no-dev in the comment: espressif/arduino-esp32#12417 (comment)
If you compare both file: https://github.com/pioarduino/platform-espressif32/blob/55.03.36/platform.json and https://github.com/pioarduino/platform-espressif32/blob/55.03.35/platform.json
There is likely a regression in the esp-idf - Issue in https://github.com/pioarduino/esp-idf/releases/download/v5.5.2.260116/esp-idf-v5.5.2.tar.xz but its ok in this version https://github.com/pioarduino/esp-idf/releases/download/v5.5.1.251215/esp-idf-v5.5.1.tar.xz
The issue occurs consistently across all examples, not just specific to one project.
TO REPRODUCE
- Update platformio.ini to use platform-espressif32 @ 55.03.36
- Flash any M5Stack example to the device (tested with M5GFX BarGraph example)
- Observe screen flickering/blinking
Here is my template
[env:m5stack_tab5]
platform = https://github.com/pioarduino/platform-espressif32.git#55.03.36
board = esp32-p4-evboard
upload_speed = 1500000
monitor_speed = 115200
build_flags =
${env.build_flags}
-I ${PROJECT_DIR}/examples/TFT_TideDisplay
-DBOARD_HAS_PSRAM
-DCORE_DEBUG_LEVEL=0
-DARDUINO_USB_CDC_ON_BOOT=1
-DARDUINO_USB_MODE=1
lib_deps =
m5stack/M5Unified @ ^0.2.13
m5stack/M5GFX @ ^0.2.19
paulstoffregen/Time @ ^1.6.1
EXPECTED BEHAVIOUR
Display should render smoothly without flickering, as it does on v55.03.35
SCREENSHOTS
Screen continuously flickers/blinks, making the display unusable
ADDITIONAL CONTEXT
- Platform Version: platform-espressif32@55.03.36
- Previously Working Version: platform-espressif32@55.03.35
- Device: M5Stack Tab5
- Framework: PlatformIO with ESP-IDF
The regression appears to be introduced in the 55.03.36 release. A revert to 55.03.35 resolves the issue immediately.
Same issue on the current main branch (3.3.7)
Key differences between 55.03.35 and 55.03.36
(Please, remember to close the issue when the problem has been addressed)
