@nebkat Yep, my patch above should fix these linking issues.

@MrSurly Could you please also run the same test with IDF Monitor, so that the backtrace gets decoded into function names? > Backtrace: 0x4202c1ab:0x3fc95770 0x40378861:0x3fc957d0 0x4037766e:0x3fc99810 0x40375dcf:0x3fc99830 0x4037e645:0x3fc99860 If you...

Looks like this is related to PlatformIO build system generating different object file names from IDF build system. This results in linker script rules not having desired effect. It seems...

It looks like that change didn't have effect, ledc_hal_get_duty was still placed into Flash instead of IRAM. I have tried reproducing the issue, with the following platformio.ini: ``` platform =...

Thank you for the reproducer! The issue is that PlatformIO doesn't make use of all the linker fragment files. Here is an excerpt from the verbose build log: ``` "/Users/ivan/.platformio/penv/.espidf-5.2.1/bin/python"...

You probably need to print the value of `sdmmc_slot_gpio_num[slot].clk` — please check the definition of `configure_pin` macro. https://github.com/espressif/esp-idf/blob/309ffa5565ad88edc262f2d6fb3e45567192bbb0/components/driver/sdmmc_host.c#L64

> thats why i currently stucked on this "clk", try to change it Sadly it's not possible: on the ESP32, SDMMC pins are fixed. The ability to route SDMMC to...

@uragan1987 Looks like you are missing pull-up resistors on D0 and CMD lines. Note that when using SD cards in 1-line mode, you still need to connect D3 line of...
