Re: esp32 P4 poor performance?
so i am still a bit confused, especially it has impact on fps on S3. I am not sure why adding this flag makes any difference on S3, either. Maybe you can try to log the pointer values returned by heap_caps_calloc with and without MALLOC_CAP_DMA and see if they are in the same memory region or not? ...

Re: esp32 P4 poor performance?
decided to write a simple bigbanging driver for it MALLOC_CAP_DMA If you are accessing a memory region by your bitbanging software driver only, there is no difference whether MALLOC_CAP_DMA is used or not. This flag requests memory which _can_ be used by DMA engines. DMA engines (like GDMA or perip...

Re: MMC/eMMC clarification - ESP32-C6
Hi Seon, The note in sdmmc_card_init about eMMC not being supported is indeed outdated. Will remove it! You are right that ESP32-C6 doesn't have SDMMC Host controller. You can call sdmmc_card_init on ESP32-C6, provided that you use SDSPI host. That is, you write: sdmmc_host_t host = SDSPI_HOST_DEFAU...

Re: dirent.h compile problem
This issue occurs because you are compiling ESP-IDF v5.3 with toolchain esp-12.2.0_20230208. The correct version for IDF v5.3 is esp-13.2.0_20240530.
Can you please describe how you are compiling the project (command line, IDE, which OS, etc.)?

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...
