IDF Patch

The patch is intended to achieve the best performance of RGB LCD by using the PSRAM Octal 120 MHz feature. The patch is only used for the release/v5.0 branch of ESP-IDF. For the master branch, the PSRAM Octal 120 MHz feature can be directly used by enabling the IDF_EXPERIMENTAL_FEATURES option.

Note: The PSRAM Octal 120 MHz feature has temperature risks and cannot guarantee normal functioning with a temperature higher than 65 degrees Celsius.

Please make sure your IDF project is clean (use git status to check), then the patch can be applied by following commands:

Manual

cd <root directory of IDF>

git apply --whitespace=fix <path of the patch>/release5.0_psram_octal_120m.patch # Nothing return if success

git status  # Check whether the operation is successful, the output should look like below:
