Considering there's already an "ESP-S3-LCD-EV-Board-2," would the name "ESP-P4-Function-EV-Board" be more suitable?

Hi.
These are 2 different boards.

Hi. These are 2 different boards. https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32s3/esp32-s3-lcd-ev-board/index.html https://docs.espressif.com/projects/esp-dev-kits/en/latest/esp32p4/esp32-p4-function-ev-board/user_guide.html

I know it. I mean the spelling of the board name should be consistent.

Please check the build errors:

@HonestQiao Check sdkconfig.defaults.esp32p4 if it works well for other P4 boards.

@HonestQiao Check sdkconfig.defaults.esp32p4 if it works well for other P4 boards.

• Please note that CONFIG_ESP_HOSTED_P4_DEV_BOARD_FUNC_BOARD is a board-specific option, and should be set in config.json.
• The remaining options are defaults and will be set automatically, so they should be removed from this file to avoid redundancy.

In my environment:

(base) ➜ [HonestQiao@cybertron] /Users/HonestQiao/Projects/ESP/xiaozhi-esp32 git:(df-p4-main) % grep -E 'CONFIG_ESP_HOSTED_ENABLED|CONFIG_ESP_HOSTED_P4_DEV_BOARD_FUNC_BOARD|CONFIG_ESP_HOSTED_SDIO_HOST_INTERFACE|CONFIG_ESP_HOSTED_SDIO_4_BIT_BUS' sdkconfig
CONFIG_ESP_HOSTED_ENABLED=y
# CONFIG_ESP_HOSTED_P4_DEV_BOARD_FUNC_BOARD is not set
CONFIG_ESP_HOSTED_SDIO_HOST_INTERFACE=y
CONFIG_ESP_HOSTED_SDIO_4_BIT_BUS=y

[78]

Yes. Here are my opinions:

• The changes to the file sdkconfig.defaults.esp32p4 can be dropped.
• The board folder can be renamed from esp32-s3-lcd-ev-board to esp-s3-lcd-ev-board to be consistent.
• The touch function code is commented out. If it's not working, we should leave some comments.

Since another PR #1243 has also modified the lcd_display.cc, please help resolve the conflicts and test if it still works.

And also address these points:

1. The board folder can be renamed from esp32-s3-lcd-ev-board to esp-s3-lcd-ev-board for consistency.
2. The touch function code is commented out. If it is not working, we should leave some comments explaining why.
