Hi
short and dirty: Done!

First test, read_mac with esptool.py and esptool32.py ok

but think, the board need a little warm air - have hot air 260°Celsius arround clock ( oszillator) and c1 and c2, will check next time in detail again, what the reason was.
a finger touch sense and this pump.
my rigol is ready for start too, i must hot air before start with modul, then bootloader and app code ok. without, there is no start possible. perhabs a toggle contact, or tempsensor? :mrgreen:

@Jeroen, think there is a cold fussion. have fluxed and then reset comes alone,
then hot air 260 °Celsius short and can switch fine. this hot air i must do allways.
will check next time whats up here.
btw: have make a switch like this now for better test:

EDIT: The name "Reset" is not the right choiced functional word,
better ( push_the_button_and_release_it ) "Power Off/PowerOn to Chip_Enable"
this will have then the cause value 1,
see the Boot Log def here:

but think you know how choice it mean

After you mentioned hot air, I gave the ESP31 IC a quick reflow and it has worked since. Thanks for the tip :)

pls try to give the ESP31 IC a cold blow ( under 20 °C celsius place temperature )
can you boot? :mrgreen:
pls watch the video in bug sector and if you can, do feedback.
if you not have a cold air too, then put the modul 1-2h in fridge :o
hey - we have a modul -40°C do +150°C ;)

think we have a nice future found?

EDIT:
( hope, because if bug, then we can't test in the winter wild , or perhabs this ESP32 beta are efused min to 20 °C in eMbeddedTemperatureSensor that we can't go outside with it :mrgreen: fun! ..but possible :o )

Hi

Are there info about boot mode 1b (upload mode ) and 3b (bootprocess) ?
what the bootloader wait for at 1b? most time then exception : epc1=0x400003638, other 0x0.. whats up :?

just in time i am in 1b if i go to upload mode (GPIO0 low) and 3b if i go to "start SPI flash" (GPIO0 high). have play a little with pins. think we have more tactics to go in boot options :mrgreen:

now, if someone know, how i come out from 1b :P
"i do not remind me to reconstrict the doings to this frame."
but will try in the meantime, like i sayed:

here comes the reconstruct you can do "follow me" by:

normaly connect and start in appliaction mode.
( high or low allways mean pullup or pulldown, i use 10KOhm)

GPIO0 high
U0TXD high
GPIO2 ( --)
GPIO05 high

boot..
Mode (33)

----

normaly connect and start in upload mode

GPIO0 low
U0TXD (--) [my are here pullup]
GPIO02 low
GPIO05 (--) [my are here pullup]

boot..
Mode (13)

----

now Mode 1b

GPIO0 low
U0TXD (--) [my are here pullup]
GPIO02 high
GPIO05 (--) [my are here pullup]

boot..
Mode (1b)

----

now Mode 3b

GPIO0 high
U0TXD high
GPIO2 ( --)---> put it to high
GPIO05 high

boot..
Mode (3b)

----

what options we have in 1b and 3b?
what are 1b and 3b?
sometimes in 1b exception : epc1=0x400003638, other 0x0.
and one info:
the flash tool can not sync in 1b, so i think, perhabs an other medium that is still missed at this time for upload space is expected?

ok.
you can now comprehend 1b and 3b as here was linked in the thread further above.
perhabs you can confirm or contradict.

next steps are listen to certain pins in 1b / 3b


best wishes
rudi ;-)


btw:
if we have 1b, have we 1a too, and the same, 3b, have we 3a too?
and what are they mean? i remind me, to saw onetime a "Xa" but do not have a second chance to go in in this.
