What is the maximum number of open files that we can have at the same time with esp-idf, and what are the configurations to get to this value?

currently we can't open more than 5. Is there a way to increase this number?

SPIFFS, FATFS?

FATFS on sdcard through spi

So,

Code: Select all

esp_vfs_fat_mount_config_t mount_config;
mount_config.max_files = (bigger number);
esp_err_t err = esp_vfs_fat_spiflash_mount(FATFS_BASE_PATH, "storage", &mount_config, &s_wl_handle);

You can mount FAT using other devices but you get the idea.
Make sure the rest of the mount_config structure suites your need.

EDIT: If you are using SD then you will need to use the MMC mount function instead, which ever function you use ATM.
