RISCV-ULP: Controlling multiple GPIOs at once

Is there an equivalent to a register write to GPIO_OUT_W1T[S|C]_REG from the ULP?

Re: esp32s3 wifi

It helps to adjust your DHCP server (running on the ESP32) to not hand out a gateway. iPhone will then instantaneously understand that there is no internet connectivity towards this AP and will use cellular for every communication not targetted at your AP's subnet.

Cutting a release for post-mortem-debugging

I'm working on preparing a proper release workflow for production. To be able to symbolicate coredump files, which parts of the `build` folder do I need to store when cutting a release? Is it just the `<project>.elf`or do I need more?

Re: bogus sdkconfig changes

Thanks, I commented on this post. Sadly, the suggested fix does not change anything for me. An `idf.py build` still mixes up a section. I wonder... if the order of components in `sdkconfig` is not relevant, perhaps I could add a post-build line (via cmake?) that just sorts the `sdkconfig` line-by-li...

Re: Is it possible to do profiling (gprof) on ESP32?

Resurrecting this old thread… it seems it's available these days via https://components.espressif.com/compon ... ssif/gprof ­-- any experiences with doing it that way? Were the results expected / accurate?

bogus sdkconfig changes

I realize this is probably more of a Kconfig question, but it's ESP-IDF I have this problem with. Whenever I build my ESP-IDF project (containing custom Kconfig projectbuild configurations), I get bogus changes in the sdkconfig like that: diff --git a/firmware/boards/ecuconnect/sdkconfig.debug b/fir...

Re: Nanosecond delay

There‘s also this https://github.com/FL0WL0W/esp-idf/tree/AMP exciting (3rdparty) project here that allows scheduling one core for FreeRTOS and the other for bare metal. Perhaps that would be of help.

Re: Any good books using Espressif tools?

I agree. Something like a modern Kolban w/ pure ESP-IDF and covering the whole ESP32 family would be something I'd love to read.
Perhaps something to write…

Re: idp.py: Changing the target programmatically

This is not really supported well by IDF (same as sdkconfig for different scenarios, like, debug and release). You will find a lot of workarounds though. I‘m using a custom board directory for every single target where the sdkconfig resides in. The rest of the files is symlinked to the general direc...
