Support for ESP32-S3-WROOM-2-N32R8V

[prschguy1]

While I see there is some support for the 16mb versions of this board, not seeing anything current for the 32mb version of it. I am using it on a couple of different builds, and I am running out of memory. Doesn't seem like I should be. Have some esp32 v1 boards that out perform this chip, and seems that shouldn't be happening. While I know that the authentic espressif boards should have memory set as opi_opi, and the generic versions of that are using quad memory. Was hoping someone here might have a board define jason that works with platformio, as well as the appropriate memory table that would go with. I know it's a big ask, but this one has been out for a while now, and from what I read, many have struggled with it. Hope someone can help.

Thanks, Craig

Thank you so much for that. Will give it a go and see if it helps the memory issue.

I use N16R8 with this "platformio.ini"
[env:esp32-s3-devkitc-1] platform = espressif32 framework = arduino board = esp32-s3-devkitc-1 board_build.mcu = esp32s3 board_build.f_cpu = 240000000L board_build.f_flash = 80000000L board_build.flash_mode = qio board_build.filesystem = fatfs board_build.arduino.memory_type = qio_opi board_build.arduino.partitions = app3M_fat9M_16MB.csv board_upload.flash_size = 16MB monitor_speed = 115200 lib_ldf_mode = deep+ build_flags = -Iinclude/ -DCORE_DEBUG_LEVEL=5 -DCONFIG_ARDUHAL_LOG_COLORS=1 -DBOARD_HAS_PSRAM=1 -mfix-esp32-psram-cache-issue -DLV_LVGL_H_INCLUDE_SIMPLE=1 -DLV_CONF_INCLUDE_SIMPLE=1

-mfix-esp32-psram-cache-issue should never be necessary on an S3 as I understand it.

That flag existed to fix an errata in the original ESP32-nothing. It's not applicable to ESP32-S3 or ESP32-anythingelse. It just throws clock cycles trying very carefully to stagger loads and stores to not trigger defects in original revs of the silicon.

ESP32-S3-WROOM-1-N16R8：
板子选择 Espressif ESP32-S3-DevKitC-1-N8 (8 MB QD,No PSRAM) ，再到platformio.ini文件下修改配置。配置如下：

[env:esp32s3]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
; 指定为16MB的FLASH分区表
board_build.arduino.partitions = default_16MB.csv
; 指定FLASH和PSRAM的运行模式
board_build.arduino.memory_type = qio_opi
; 预定义宏，启用PSRAM
build_flags = -DBOARD_HAS_PSRAM
; 指定FLASH容量为16MB
board_upload.flash_size = 16MB

ESP32-S3-N32R8:
板子选择 Espressif ESP32-S3-DevKitC-1-N8 (8 MB QD,No PSRAM) ，再到platformio.ini文件下修改配置。配置如下：

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
;lib_ldf_mode = deep+	#在搜索库依赖关系时使用 "深度+" 模式
board_build.arduino.partitions = default_16MB.csv	
board_build.arduino.memory_type = opi_opi	#8MB PSRAM的运行模式
build_flags = -DBOARD_HAS_PSRAM		#用于指示编译器当前的目标设备是否具有 PSRAM
	-mfix-esp32-psram-cache-issue #用于修复 ESP32 上的 PSRAM 缓存一致性问题的编译选项
board_upload.flash_size = 32MB #FLASH大小
#添加的库
; lib_deps = 
; 	bblanchon/ArduinoJson@^6.21.2
; 	lvgl/lvgl@^8.3.7
; 	bodmer/TFT_eSPI@^2.5.30
; 	lorol/LittleFS_esp32@^1.0.6

其中最主要的就是“board_build.arduino.memory_type = opi_opi”，查看官方文档可以发现ESP32的PSRAM的运行模式是有Quad SPI和Octal SPI的区别的，而8M的PSRAM使用的是Octal SPI，默认的Quad SPI是运行不了的。
