Re: esp32-c6 and external PSRAM?

The recently-announced ESP32-C61 (lower cost version of ESP32-C6) will include PSRAM support to compensate for the smaller amount of the internal SRAM.

Re: Help with coredump; using saved downloaded core file not working as expected

I think this should work if you use 'raw' type, pass the core dump (as obtained from Flash partition) to the --core argument, and also include the application ELF file as the last positional argument. Something like this: espcoredump.py info_corefile --core coredump-from-flash.bin -t raw project.elf

Re: Pin Function/ Descriptions

Hi Ben, FSPI signals are described in "Table 30-­3. Functional Description of FSPI/SPI3 Bus Signals" of the ESP32-S3 technical reference manual . Other signals like SPI and SUBSPI are used only for connecting SPI Flash or PSRAM, and are typically handled by the low-level drivers (e.g. in ESP-IDF). N...

Re: Unity / Unit Test app

Hi Gabriel_Simmann, Could you please check whether you have CONFIG_UNITY_ENABLE_IDF_TEST_RUNNER option enabled in sdkconfig? Perhaps the issue is due to the fact that the feature which provides these TEST_CASE macros is disabled. Another thing to try, what happens if you add this additional file int...

Re: Running on single core variant of a chip, but app is built with multi-core support.

Hi jnorrish, Until 2021, ESP32-Mini-1 module was shipped with a single core variant of the ESP32. This changed in 2021 when the module was upgraded to the dual-core version. See this product change notification . Page 4 shows the difference in module markings. Looks like one of the modules is indeed...

Re: Dynamically resizing SPIFFS partition to "largest possible"

Hi RandomInternetGuy, The partition table is stored in a single flash sector without redundancy. I'm afraid that overwriting it at run time may lead to the device getting bricked, if the power gets disconnected at the right (or wrong) moment. If the partition table has been erased but not written an...

Re: millis() and light-sleep

It is possible that this hasn't worked in the first arduino-esp32 release, v1.0.0 , which came out in July 2018. arduino-esp32 uses esp_timer_get_time IDF function to implement millis, and esp_timer_get_time has maintained time in light sleep since IDF v3.1 , released in September 2018. If you have ...

Re: JTAG error with ESP32-S3-DevKitC

Is it necessary to program the S3-DevKitC via serial before trying to do JTAG? I went straight to JTAG right out of the box and had errors. It depends on whether the program flashed into the chip is reconfiguring USB pins or not. If it does, you might have flash some temporary program (like "blink"...

Re: Using esp-protocols with vscode extension

Hi Joel, You can add any of the components in esp-protocols to your project from IDF component registry. For example, mdns can be found here: https://components.espressif.com/components/espressif/mdns You can add it either by running the "idf.py add-dependency "espressif/mdns^1.2.0" command in your ...

Re: POSIX time functions in STUB

Hi aravind.h615,

No, unfortunately you can't. POSIX time function depend on a large amount of code in C standard library which only gets loaded along with the application, most importantly the port layer which maps POSIX functions to hardware functions. That code simply can't fit into the RTC RAM.
