Answers checklist.

• I have read the ESP-DSP documentation and the issue is not addressed there.
• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my ESP-DSP branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

IDF 5.2 latest master

Module or chip used.

Compile try for ESP32-P4

DSP version.

latest master

What is the expected behavior?

Code compiles

What is the actual behavior?

compile error with modules/dotprod/float/dsps_dotprode_f32_arp4.S:52: Error: unrecognized opcode esp.lp.setup 0,a3,.dotprod_loop'

Steps to reproduce.

Hi @Jason2866,
Thank you for feedback.

Could you try to switch to latest idf master branch?
Then ./install.sh and then . ./export.sh

Now only latest master has a toolchain to support esp32p4 instructions like esp.lp.setup

Please let me know the result.
Thank you.

Understood, branch IDF 5.2 is not supported. Can't change to IDF master branch easily, many code changes needed. Will the needed changes backported to IDF 5.3.x and 5.2.x?
If not, no drama will exclude DSP lib when compiling for P4
Imho the idf_component.yml should be adopted to reflect the needed versions of IDF

@Jason2866 I think it's a plans to make a backport.
Now, you can just take binutils from latest master, and use them.
Yes, I will add restriction to idf_component.yml
Thank you.

Also, you can now disable optimization for esp-dsp in menuconfig, and you will be able to use the esp-dsp. For floating point operations, you will not lose a lot of performance. And in future will fix the problem.
