Add board WT32-SCO and WT32-SCO-Plus

[zackees]

Does anyone know which board I can select as a work around?

I can compile and flash but esp_highmem_get_phys_size() and esp_himem_get_free_size() both crash when called.

  esp_himem_get_phys_size();
  esp_himem_get_free_size();

Results in

E (153) spiram: SPI RAM not initialized

abort() was called at PC 0x400df714 on core 0

This happens for the following platformio.ini configurations:

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:WT32-SC01]
platform = https://github.com/platformio/platform-espressif32.git
board = wt32-eth01
framework = arduino
upload_speed = 921600
monitor_speed = 115200
monitor_filters = 
    default
    esp32_exception_decoder
;board_build.f_flash = 80000000L
build_flags =
  -DCORE_DEBUG_LEVEL=2
    -DBOARD_HAS_PSRAM
    -mfix-esp32-psram-cache-issue
    -I src/

And also:

board = esp-wrover-kit

And also:

board = esp32dev

I'm using VSCode with the arduino framework. It happens with the release:

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

And also:

platform = espressif32

The error says that it can't enable spiram, which is interesting because the WT32-SCO uses psram. I can access and use the first 4mb of psram on the chip, which I've confirmed works with a memory test:

 void *memory = ps_malloc(100000);
 memset(memory, 0, 100000);
 free(memory);

This issue only affects the upper 4mb high memory.

You cant address more than 4MB PSRAM with the ESP32.

[zackees]

The internet reports that people are accessing the upper 4mb psram through high mem bank switching. At the very least calling this function should not crash the system.

[Jason2866]

Anyways, not a platformio issue.

Does anyone know if this is issue is fixed with ESP-IDF v5.X?

I see that platformio latest (5.2.0) currently uses ESP-IDF v4.4.2 and proper support for the WT32-SCO board might have come after ESP-IDF v.4.4.2. It could just be a fix waiting for an upstream merge with the new toolchain.

@zackees You can use this project for WT32-* boards. Once PIO support for IDF 5.0 happens, will add the support in the project. https://github.com/sukesh-ak/ESP32-TUX/

@zackees And ESP-IDF himem sample is here https://github.com/espressif/esp-idf/tree/release/v5.0/examples/system/himem

hi, i was wondering if there is any progress adding these boards?
