ESP32-S3
DevKitC
NA
v3.1.2
Arduino IDE
yes
Because the mux offsets timing, many eMMCs need the phase to be adjusted, to obtain high transfer speeds. see espressif/esp-idf#12952
in esp-idf I can do :
sdmmc_host_t host = SDMMC_HOST_DEFAULT(); host.input_delay_phase = SDMMC_DELAY_PHASE_1;
Which will work at high speed with my eMMC, which is KLM8G1GETF-B041.
In Arduino this is not possible, so many eMMCs will not work at high speed, and with DDR.
Would it be possible to add this property to the next release?
thank you!
