Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

In [ESP-IDF Programming Guide]
(https://docs.espressif.com/projects/esp-idf/zh_CN/v4.4.3/esp32s3/hw-reference/esp32s3/user-guide-devkitc-1.html?highlight=37) it says ：
“板载 ESP32-S3-WROOM-2 模组系列的开发板中，管脚 GPIO35、GPIO36 和 GPIO37 已用于内部 ESP32-S3 芯片与 SPI flash/PSRAM 之间的通信，外部不可使用。”
it is easy to make me believe that GPIO 35-37 of ESP32-S3-WROOM-1 are free to use, however, this is not the truth. GPIO 35-37 of ESP32-S3-WROOM-1 with OSPI could not be used either.
SO I THINK THE SENTENCE IN PROGRAMMING GUIDE MAY BE MISLEADING!
