ESP-ADF and ESP-DSP

Postby thefury » Thu Sep 26, 2019 10:53 pm

I've written some custom DSP code into a pipeline and I've run out of CPU time (even splitting across cores) so it would appear I need some optimized instructions to proceed further in my development.

In trying to load up ESP-DSP to see about integrating those optimized functions into my application, I've hit a snag. ESP-DSP doesn't compile as-is in my current setup.

I have tried with the downloaded toolchain (1.22.0-80-g6c4433a) as well as building the toolchain from source. My host system is ubuntu 18.04 and I'm working with a LyraT 4.3 board.

esp-idf version is at v3.3, adf (although unrelated since I'm just trying to build a dsp example outside of ADF for now) is currently v2.0-beta1-47-gdf76962

What version of esp-idf, esp-adf, esp-dsp, and xtensa-esp32-elf should I be using?

I am experiencing the same issue. I use the board lyraT 4.3, ESP-ADF and ESP-DSP and added the dsp component manually with the git clone command.

I appear to have found a fix for this particular issue: https://github.com/espressif/esp-dsp/pull/9

If you'd like to try it, you can make the same edit to that file in your local copy, I think.
