Re: Write filesystem to spiffs

Can we not get an Espressif engineer to comment on this? I ask because it's part of the official v3.1.1 documentation posted on the Espressif site that this is supported, and it does not work.

Re: Flash memory available

The partition that holds your code in flash is defined by the partition file. You then take whatever flash that isn't being used as defined by the partition file, and create a partition to hold your MP3 files. When you burn the flash with your firmware it shows you how much is being written. You can...

Re: Write filesystem to spiffs

So now I've downloaded the file via HTTP and wrote it to the file system. I can read it back in my application. But if I use esptool to read the partition into a bin file, mkspiffss fails to mount the FS. I am using the latest mkspiffs build and the version info verifies it's built for the ESP32.......

ESP_PLATFORM has been the one I've used, but that one has been removed, at least when building using CMake in current master. There is a PR to get it back: https://github.com/espressif/esp-idf/pull/2601
ESP_PLATFORM works with my release 3.1.1 IDF. Looks like I'll use that for now.

Re: Easy question!

Turns out this is a hard question. I searched the IDF components for #ifdef and only found one related to the BUILD as.. #ifdef ESP32. But appears in the rom files and isn't defined during a regular application build.

Easy question!

When I compile with the IDF what definition can I expect to exist that indicates it's being built on the ESP32? Like say...

#ifdef ESP32_IDF
#include <FreeRTOS.h>
#endif

Re: Write filesystem to spiffs

Hi, I used https://github.com/loboris/ESP32_spiffs_example.git because it has directory support. I only added a few large Gutenbergs to the example (no code or build changes) but seemed to serve them up well enough. I'm not really interested in viewing directories. Were you able to burn a file syst...

Re: ESP-IDF SPIFFS can't find files on ESP32?

Did you guys ever figure out how to write a file system to the flash where you could read the files? I just tired this and couldn't get it to work. I started another thread with more details.

Wait for the HTTP_EVENT_ON_FINISH callback.

Re: OTA Does not seem to work if you use AP or Repeater

Any time you cross subnets you need gateways and routing. Without knowing what your IP subnets and gateways are from one end to the other it's normally hard to know where the issue lies. Except..... I did a little googling on Arduino and OTA. It appears that the name of your ESP32 is broadcast over ...
