Hi
I am trying to get a newer version of the espressif32 framework to compile some older code - where I have a bit of challenges.
The original platformio.ini file has this:
platform = espressif32@1.12.2
board = esp32dev
framework = arduino
The original source has a fseek hack/patch included - which apparently should be in the espressif 32 framework now according to expose FF_USE_FASTSEEK in menuconfig (IDFGH-3696) · Issue #5625 · espressif/esp-idf · GitHub
The question is just how to enable it from VSCode/PIO ?
I assume, that I somehow need to add build flags like this ?
build_flags =
-D FATFS_USE_FASTSEEK=y
-D FATFS_FAST_SEEK_BUFFER_SIZE=64
But I have tried both with and without these flags - and see no change in performance on the test-code on GitHub - michael-betz/fast_seek_test: Benchmark ESP32 seek times on FAT32 FS with platform = espressif32@6.1.0
Any hints ?
Regards
Brian
You cannot affect the ESP-IDF build parameters with build_flags in a framework = arduino project because the ESP-IDF library is precompiled. The code has already been generated. Also the right parameter is called CONFIG_FATFS_USE_FASTSEEK.
Arduino-ESP32 2.0.14 has that disabled. (Same for latest 3.x)
To use a modified ESP-IDF base in your Arduino project, use https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-arduino-blink as the starting project, then use the menuconfig to enable CONFIG_FATFS_USE_FASTSEEK.
This will be in turn used in the FF config.
Actually that’s an interesting hack. It just also compiles the ff libary source code with its own config and then hopes that the linker will use its implementation instead of the one built into ESP-IDF? That’s uh, smart.
Trying out to compile right now…
I hope, that the newer version of the framework maybe has libraries for makign it easier to implement a mqtt client in the original code (that utilizes the fseek stuff) … That is the main reason for trying to run it in a newer framework…
Not quite there yet, uploading the code and running it gives me:

Does the referenced mininmal example espidf-arduino-blink work fine?
That one works file… Re-arranging the code in the perfomance test example and adding a dealy(1); seems to help - now the watchdog is not being triggered any more - and the output gets like:

[228591][I][Blink.cpp:67] loop(): fseek( 104886275) dt: 704 us, read 4096
So far, so good. Now this issue is just whether I can get the “main” project converted as well…
Mission almost accomplished.
With the old/original framework a spiffs partitions.bin file was automatically created, maybe based on some of the dependent libs ? That is the last thing I need to sort out now, as the compiled code seems to run without triggering the watchdog.
Thanks for the input so far - I am much closer in being able to get things up and running with a newer framework now
