hi
before work on First Start with electric on the ready soldered ESP board i ask before,
because we have only one module and i would work long time in beta ( greetings to Kolban, i soldered, but i do not know, did it fine too)

which process you do for first start?
soldering
3.3 -> Pin name 3.3
GND ->Pin name GND
3.3 -> Pin name EN

( do we need to connect GPIO15 and other ( GPIO02, GPIO00 ) like ESP8266?)

which is the the HW RST pin (Chip Pin 47? ) on the ESP_Module_Testboard?

have we a table for boot mechanism / processing available just in time?

Can we HW reset the Modul? txs

i think EN can be used to reset the device.
that said, i'm not having much success flashing the device, so take it for what it's worth...

rudi, can the below boot mode configuration help you out?

txs, yes - this helps.

btw:

we have the Chip_En pin
this pin is no reset pin. if the pin goes Vcc + then the SoC is 100 prozent active
if the pin goes Low, the SoC works in which Mode?

deep deep sleep? ( only RTC is working )
deep sleep? ( Modem is off, CPU is working )
sleep ( Modem is listen, trigger to wake up with Res 14k ? as a RST

can / have we later in ESP32 a real RST Pin ( reboot function in SSC ) ?

txs

is there are nice Mode for watching Pin ISR in deep deep sleep?

The Chip_En pin is the same as on the ESP8266: if it's pulled low, the chip is entirely disabled, which is functionally the same as it being in reset state. That's why you can use it as a reset pin; it has the same effect. Yes, there is a very nice mode for watching pins (and A/D, and capacative sensors, and...) in deep sleep; unfortunately we don't have the documentation for it ready as of now.
