Re: eth_clock_mode_t for ESP32 WROVER

ETH_CLOCK_GPIO0_OUT should be re-added soon!

Re: Can LuaJIT be build for ESP32?

Have you looked at using Sol2 / Sol3 for doing Lua bindings? I've used it (on another MCU platform, not ESP32) and it is pretty awesome.

Re: skipping incompatible libraries

Can you also try running

file /opt/esp-idf-sdk/components/esp32/lib/libcore.a

and see what it says?

Re: ESP32 SD Card in MMC-mode

Most likely it's something with D1-D3 lines, since CLK/CMD/D0 are used in 1-line mode and you don't observe issues there.

Keep in mind that there may be a pull-down on GPIO12, depending on the development board. If it is present, it may be conflicting with your external pull-up.

Re: where is the GPIO37 and GPIO38?

These GPIOs are not broken out on modules such as WROOM and WROVER, but are available if you use the bare chip.

Re: ESP32 SD Card in MMC-mode

0x109 is CRC error. Usually this means either signal integrity (interference/long wiring/etc) issue or voltage levels issue. Try reducing clock frequency to 400kHz. If it doesn't help, check if all the pull-up resistors are in place. Use oscilloscope to scope the signals and see whether they look ok...

Re: Including files in one custom component from another

Does it work if you include "componentA.h" (as your include path is already set to ComponentA/include)?

If not, please post the output of "make V=1".

Re: Low power strategies without resorting to sleep modes

Power Management APIs don't allow you to lower the CPU frequency to <80MHz for normal operation. However when the CPUs go into idle state and all power management locks are released, the system can go to a lower 10/20/40MHz frequency. Wait-for-interrupt state of the CPU indeed doesn't contribute muc...

Re: Sleep mode and Wake up when CAN is active

esp_restart() does a full reset of all peripherals It only resets some of the peripherals: UART, SPI, SDIO... CAN is not reset, I think. However if you want to reset the CAN you can call periph_module_reset function. How can I do a full restart like with a hard reset? The closest you can get is an ...
