Support for EPS32-PICO-V3

rezza · April 3, 2022, 8:50am

Hi,
I am recently trying out ESP32-PICO-V3-02 chip but I noticed this board is not listed in PlatformIO.
So I am wondering how I can unlock the real 8MB flash and internal PS-RAM probably.

maxgerhardt · April 3, 2022, 12:44pm

Per schematics it’s just an ESP32 with 8MB flash + 2 MByte PSRAM chip (https://www.espressif.com/sites/default/files/documentation/esp32-pico-v3-02_datasheet_en.pdf).

Have you tried

[env:esp32dev]
platform = espressif32
boad = esp32dev
framework = arduino
board_build.partitions = default_8MB.csv
build_flags =
    -DBOARD_HAS_PSRAM
    -mfix-esp32-psram-cache-issue

? (docs)

rezza · April 3, 2022, 6:59pm

Thanks for your reply.
I think I managed to use the 8MB flash using your suggestion.

board_build.partitions = default_8MB.csv

But I am guessing I need the latest Ardunio core to get access to the PS-RAM, otherwise, the MCU keeps rebooting with the following error code.

E (180) psram: Not a valid or known package id: 6
abort() was called at PC 0x40084f87 on core 0

ELF file SHA256: 0000000000000000

Rebooting…

Do you know which version of Ardunio is used in Platform-Espressif32 v3.5.0?

maxgerhardt · April 3, 2022, 7:01pm

It’s the older 1.0.6 version.

Can you try setting

platform = https://github.com/Jason2866/platform-espressif32.git

instead in the platformio.ini?

rezza · April 4, 2022, 3:31pm

Yes, that works perfectly fine.
I guess I need to stay in an unofficial branch for a while.

Do you have it in the roadmap?

bug build system

What kind of issue is this? - [X] **PlatformIO Core**. If you’ve found… a bug, please provide an information below. *You can erase any parts of this template not applicable to your Issue.* ------------------------------------------------------------------ ### Configuration **Operating system**: Win10 x64 **PlatformIO Version** (`platformio --version`): 5.2.5 ### Description of problem See https://github.com/espressif/arduino-esp32/issues/6463 and [forum](https://community.platformio.org/t/working-with-esp-arduino-2-0-2/26540/6?u=maxgerhardt). The Arduino-ESP32 PlatformIO builder script tries to generate a `.map` file via the [code](https://github.com/espressif/arduino-esp32/blob/0b10c8b79ef3edb88709f5da9e751578abdf2877/tools/platformio-build-esp32.py#L115) (simplified) ```py env.Append( LINKFLAGS = [ #... '-Wl,-Map="%s"' % join("$BUILD_DIR", basename(env.subst("${PROJECT_DIR}.map"))) ] ) ``` However, PlatformIO or SCons seem to not be able to evaluate this correcty. If the project is e.g. in the path `C:\Users\Max\temp\Test Project With Spaces`, the generated commandline is ``` -Wl,-Map="C:\Users\Max\temp\Test Project With "Spaces\.pio\build\esp32dev\Test Project With Spaces.map"" ``` which as an extremely weird `"` at the last space in the project path (`$BUILD_DIR` presumably). As a result, the linker command is messed up and errors out, leaving users with a space in their username or project path unable to build Arduino-ESP32 2.0.2 firmwares. How can the builder script be written so that the argument of the form `-Wl,-Map="%s"` is not further messed with by SCons or PlatformIO? The path escaping is already done here after all. P.S.: Using `-Wl,-Map` followed by just the path does not seem to work, GCC seems to need it as one flag. #### Steps to Reproduce 1. Create a new folder with a space in it 2. Execute `pio init -b esp32dev` in it 3. Overwrite the `platformio.ini` with the one shown below 4. Use the minimal C++ code shown below 5. Attempt compilation ### Actual Results Linking failure due to weird double quoting. ``` Linking .pio\build\esp32dev\firmware.elf xtensa-esp32-elf-g++: error: Project: No such file or directory xtensa-esp32-elf-g++: error: With: No such file or directory xtensa-esp32-elf-g++: error: Spaces.map: No such file or directory *** [.pio\build\esp32dev\firmware.elf] Error 1 ================[FAILED] Took 102.29 seconds ================ ``` ### Expected Results Succcessful compilation since the builder script correctly escapes paths with a potential space in it with quotes. ### If problems with PlatformIO Build System: **The content of `platformio.ini`:** ```ini [env:arduino-esp32] platform = https://github.com/Jason2866/platform-espressif32.git board = esp32dev framework = arduino platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32#master ``` **Source file to reproduce issue:** ```cpp #include <Arduino.h> void setup() {} void loop(){} ``` ### Additional info

Should this work now properly without any custom branches? =)

Does not work here on my side

[env]
platform = espressif32
board = esp32dev
#board_build.partitions = default_8MB.csv
build_flags =
-DARDUINO_ARCH_ESP32
-DBOARD_HAS_PSRAM
-mfix-esp32-psram-cache-issue
framework = arduino
upload_port = /dev/ttyUSB0
monitor_port = /dev/ttyUSB0
monitor_speed = 115200

once I uncomment the default_8MB.csv line, the device will not boot anymore and prints errors that it cannot boot…

The “percentage” updates… but that doesnt help if its not booting

maxgerhardt · October 27, 2022, 9:21am

With which settings does it work in the Arduino IDE?

slaesh · October 27, 2022, 9:38am

Thanks Max,

I don’t know, I don’t use the Arduino IDE

VS-Code + PlatformIO

maxgerhardt · October 27, 2022, 9:43am

Well does your board have 8MB flash? Pleas execute <python> esptool.py flash_id in accordance to Upload failed on esp-wrover-kit (framework = arduino, espidf) - #2 by maxgerhardt and post the output here.

Please install the Arduino IDE + Arduino-ESP32 2.0.5 core and test with the same configuration (done via the Arduino IDE → Tools menu). That way we know whether PlatformIO is at fault or the core itself.

Did you also try the simplest possible blink + print sketch in PlatlformIO with the 8MByte partition table? Your sketch seems quite extensive.

slaesh · October 27, 2022, 5:56pm

this works… at least does not crash

but I have no clue what they exactly do? can find any settings saved anywhere… this IDE is horrible

maxgerhardt · October 27, 2022, 6:02pm

Then let’s equalize the settings accoding to the docs. Can you use the following platformio.ini:

[env]
platform = espressif32
board = esp32dev
framework = arduino
; PSRAM: "Enabled"
; Core Debug Level: "Verbose"
build_flags =
  -DBOARD_HAS_PSRAM
  -mfix-esp32-psram-cache-issue
  -DCORE_DEBUG_LEVEL=5
; Partition Scheme: "8M with spiffs"
board_build.partitions = default_8MB.csv
; Flash Mode: "QIO"
board_build.flash_mode = qio
; upload + monitor sports and speed
upload_port = /dev/ttyUSB0
monitor_port = /dev/ttyUSB0
monitor_speed = 115200

And use the exact some source code as in the Arduino IDE in your src/main.cpp.

slaesh · October 27, 2022, 6:14pm

stripped it down…

platformio result is:

RAM:   [=         ]   5.0% (used 16520 bytes from 327680 bytes)
Flash: [=         ]   7.7% (used 257305 bytes from 3342336 bytes)

and arduino result is

Sketch uses 262409 bytes (7%) of program storage space. Maximum is 3342336 bytes.
Global variables use 16520 bytes (5%) of dynamic memory, leaving 311160 bytes for local variables. Maximum is 327680 bytes.

so its very close… but still crashing

What are the bootloader messages after flashing it with the Arduino IDE but opening the serial monitor in PlatformIO and pressing the reset button?
