if we use ESP32-D2WD with embedded Flash we need to be noted that the memory used 1.8 V, right?
we can then use the regulator by pullup on MTDI, or burn appropriate efuses using espefuse.py tool
Code: Select all
$IDF_PATH/components/esptool_py/esptool/espefuse.py set_flash_voltage 1.8V
how we connect PSRAM32 on ESP32-D2WD ?
there are several rules to be noted?
expanded bootstrap pins for this ?
we can connect a parallel Flash?
We can decide which (eMbeddedFlash) or SPI Flash is to be used as a boot and can we access the slave? (Master slave principle?)
Have we a boot flag in the efuses for using eMbeddedFlash / SPI Flash?
If we use ESP32-D2WD have we more GPIO then for free, cause it's eMbeddedFlash ?
