Hi ignisuti, 'main' component has a special behavior that by default, it adds all other components as dependencies. This is the reason why you can use nvs_flash component from "main" without explicitly adding nvs_flash as a dependency. Once you start creating additional components, you have to expli...

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? ...

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...

Hi Seon, The note in sdmmc_card_init about eMMC not being supported is indeed outdated.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...

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.)?

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.

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

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...

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...

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...
