Does file_serving example support SD Card?

Source code:

https://github.com/espressif/esp-idf/tree/master/examples/protocols/http_server/file_serving

First of all first forgive my fractured English, it's not my native language.
I'm a newbie in programming and I'm having a hard time trying this example to work with my SD Card, I tried another similar program in Arduino IDE without problems but in ESP-IDE I can't make it work as the default path for file serving to the SD Card, And it's all correctly configured with idf.py menuconfig

When I try to mount the file server to /sdcard i get the following error:

Code: Select all

"file server presently supports only '/spiffs' as base path"

The SD Card it's correctly mounted but I can't use it to upload files or for file listing, because the default path for file serving its/spiffs

Code: Select all

I also could not get this to work by following the directions in the readme / menuconfig.

I did get file_serving to use the sdcard by doing the following.

1. enable sdcard in menuconfig

2. in main.c, line 87 change the esp_vfs_spiffs_conf_t struct to use /sdcard

esp_vfs_spiffs_conf_t conf = {
.base_path = "/sdcard",
.partition_label = NULL,
.max_files = 5, // This decides the maximum number of files that can be created on the storage
.format_if_mount_failed = true
};

3. in main.c, line 237 ESP_ERROR_CHECK(start_file_server("/sdcard"));

4. in file_server.c line 450, comment out the check for the base_path - lines 451-455

Then it should work.

If I have it right, vfs stands in front of spiffs, which is in a file system on an nvs partition, or fat32, which is a file system on sdcard. I have no idea why they have that check for spiffs in there.

And, your English is fine. It is better that many native writers here in Vermont, USA.

Hello,

Please note that "file_serving" example from ESP-IDF was recently refactored and it already includes some of the suggestions discussed here. Please find relevant commit at: https://github.com/espressif/esp-idf/co ... e581ef446b

Could you please try latest example from master branch and share your feedback?

Thanks.

Hi, I use ESP-IDF(V4.4 stable) and change code follow your way. But actully I find it just change string "/spiffs" to '/sdcard' , you can see the log still printing :"I (5640) example: Partition size: total: 896321, used: 0".So it still use flash as storge, and I try some way prove my opinion is right.(e.g. Upload the file then reset code and unplugged the sdcard，you can see the file can be checked forever.)
