Documentation docs/gettingstarted/installer.md |
Updated ESP32 LED capability wording: now specifies "up to 1024 LEDs at 30 FPS on a single output" or "4096 LEDs over Art-Net/network" instead of a single "up to 4096 LEDs" statement. |
Firmware configuration firmware/esp32-d0.ini |
In env:esp32-d0-pico2, added PSRAM-related settings and build flags: board_build.arduino.memory_type = qio_qspi, board_build.flash_mode = qio, -DBOARD_HAS_PSRAM, and -mfix-esp32-psram-cache-issue; adjusted partitions/comment formatting. Review build behavior for PSRAM and flash mode changes. |

Poem
🐰 I hopped through docs with bright delight,
Counted LEDs by day and night,
Flags for PSRAM set just so,
Builds may change — hop nice and slow,
Cheers to clearer paths aglow ✨

@coderabbitai, I have this new esp32 MCU definition: [env:esp32-d0-pico2] And used it to flash to a ESP32-PICO-Mini-02 : ESP32 based, Dual-Core 240Mhz microcontroller, 8MB Flash, 2MB PSRAM, more info here: https://documentation.espressif.com/esp32-pico-mini-02_datasheet_en.pdf In esp32-d0.ini, imported in platformio.ini I used board = esp32-pico-devkitm-2 which I believe takes the definition from https://github.com/platformio/platform-espressif32/blob/master/boards/esp32-pico-devkitm-2.json (can you check it this is how it works using board =). When flashing I got this: [13:50:02]ELF file SHA256: 7dc328089 Can you investigate what is going on? And propose changes to my [env:esp32-d0-pico2] if needed, to make this definition work for ESP32-PICO-Mini-02 |

@coderabbitai, regarding
When I use board_build.partitions = boards/ESP32_8MB.csv I got: Error: The program size (2349899 bytes) is greater than maximum allowed (2097152 bytes) why is that? as it exists in the boards folder... (check it's contents please) but when I used default_8MB.csv it works fine: RAM: [== ] 18.8% (used 61728 bytes from 327680 bytes) You say it is not defined in boards but isn't this some globally available definition? Furthermore regarding
In https://github.com/platformio/platform-espressif32/blob/master/boards/esp32-pico-devkitm-2.json I can find "extra_flags": [ "flash_mode": "qio", there is only not arduino.memory_type = qio_qspi so we don't need to specify -DBOARD_HAS_PSRAM and oard_build.flash_mode = qio isn't it? and do we need -mfix-esp32-psram-cache-issue for this board? So concluding: the only real change you propose is adding arduino.memory_type = qio_qspi and maybe -mfix-esp32-psram-cache-issue. Is that indeed what was missing bottom line? |

Partition File ClarificationYou're right: The key difference:
So stick with Board JSON FlagsYou're also right about the redundant flags! The board JSON at
So you don't need to re-specify these in your platformio.ini. What About -mfix-esp32-psram-cache-issue?This flag is still recommended because:
Looking at your Bottom Line: The Actual FixYes, you're exactly right! The minimal changes needed are: [env:esp32-d0-pico2]
board = esp32-pico-devkitm-2
board_build.partitions = default_8MB.csv ; Framework default with 3.3MB app partitions
board_build.arduino.memory_type = qio_qspi ; ← THIS was missing (enables PSRAM)
build_flags = ${esp32-d0-base.build_flags}
-D HTTPD_STACK_SIZE=6144
-mfix-esp32-psram-cache-issue ; ← Safety for ESP32 Rev1 cache bug (optional but recommended)
lib_deps = ${esp32-d0-base.lib_deps}Root Cause of Original CrashThe LoadStoreError happened because:
The core dump error was just a side effect of the crash happening early in boot before that partition was initialized. TL;DR: You nailed it — ✏️ Learnings added

@coderabbitai, still same crash. I read somewhere else ( MoonModules/WLED-MM#322 ), maybe related?: _Switching to flash_mode = dio: The standard QIO mode was too unstable when the HUB75 driver was active, leading to flash write failures. So should I change qio to dio? Please also explain what it does, maybe @intermittech had the right setting for this after all 🙂 |

DIO vs QIO ExplainedQIO (Quad I/O): Uses 4 data lines for flash communication, up to 4× faster than standard. DIO (Dual I/O): Uses 2 data lines for flash communication. Performance order: QIO > QOUT > DIO > DOUT The key difference: In QIO mode, two additional GPIOs are used for SPI flash communications (SPIWP and SPIHD pins). If flash mode is set to DIO then these pins are available for other purposes. Pin Conflicts with HUB75 and Other DriversYour codebase does use HUB75 drivers (found When using high-bandwidth drivers (HUB75, parallel LED drivers), QIO mode can cause:
The WLED-MM reference you found is highly relevant — switching to DIO resolved HUB75 driver instability there. But Wait — PICO-D4 Caveat!However, I found a conflicting report: When flashing with QIO mode all is well, when flashing with DIO mode the sketch fails to talk the the built-in flash correctly on PICO-D4 boards. This suggests PICO boards may have unique flash wiring that actually requires QIO. Critical QuestionsBefore recommending DIO, I need to understand the current situation:
The fact that you're still getting the same crash suggests one of two things:
What to TryOption 1: Verify current config and check boot log [env:esp32-d0-pico2]
board = esp32-pico-devkitm-2
board_build.partitions = default_8MB.csv

-mfix-esp32-psram-cache-issue
lib_deps = ${esp32-d0-base.lib_deps}Check the boot log — does it say Option 2: Try DIO flash mode (if Option 1 confirms PSRAM is initialized but still crashing) [env:esp32-d0-pico2]
board = esp32-pico-devkitm-2
board_build.partitions = default_8MB.csv

Root Cause AnalysisThe QuinLED DIG Next 2 preset assigns 17 GPIO pins (lines 371-390: 12 LED pins, 2 button pins, 2 I2C pins, 3 exposed pins). This creates deeper call stacks during initialization. The crash sequence:
What Are IPC Tasks?IPC (Inter-Processor Call) tasks are ESP-IDF system tasks that handle communication between Core 0 and Core 1. They're used when one core needs to execute code on the other core (e.g., flash operations must suspend both cores). Default IPC stack size is 1024 bytes. With only 404 bytes free, any moderately deep call stack will overflow — especially during WebSocket connections which trigger network processing + JSON parsing + flash operations. Why Other Boards Don't CrashOther boards likely:
404 bytes free is critically low — you're on the edge of overflow constantly. The SolutionIncrease [env:esp32-d0-pico2]

Memory ImpactIncreasing from 1024 → 2048 costs only 2 KB of RAM (1 KB per core for the two IPC tasks). This is negligible compared to your 327 KB total RAM. Why the Cache Error AppearedWhen the IPC task stack overflowed during a flash operation:
This is a secondary symptom — the root cause is the stack overflow. After Applying the FixAfter adding
This aligns with the learning about task stack sizing for high-load scenarios — adequate headroom prevents watchdog timeouts and stack overflows! 🎯 Try the fix and let me know if the crashes stop! 🧠 Learnings used |

@coderabbitai, regarding
That is not true, only 2 LED pins. And currently the 2 I2C pins, and 3 exposed pins are not used yet, so I doubt if this is the problem. Moreover, the software runs on all other boards (ESP32-D0, S3 and P4). and regarding
that did not make a difference If I look at the tasks free idc memory, still around 400 bytes. Is this the right command? so could you dig deeper? |

board_build.flash_mode = dioThis uses fewer pins and may have more conservative PSRAM allocation. Why My Analysis Was Wrong BeforeI incorrectly assumed:
