Thanks rojer9.

Code: Select all

$ ./esptool32.py --port /dev/tty.usbserial-FTH159YK read_mac
Connecting...
Traceback (most recent call last):
  File "./esptool32.py", line 557, in <module>
    esp.connect()
  File "./esptool32.py", line 171, in connect
    raise Exception('Failed to connect')
Exception: Failed to connect
My logic analyser is sitting on the end of the through-hole pin, and the castellation is very visibly connected. I suppose the next step is to put a flying wire on the QFN pad and see what's happening there.

hi
only a question, my first start up starts in few minits:
have checked soldering and board pins, all ok.

have we a bootloader prompt to see ( identify as bootloader mode ) in terminal or comes blank screen? if bootloader prompt, what / how does it say / looks it?

i will start then:
connect GND,
connect 3.3
connect EN to 3.3
GPIO0 to low ( GND )
GPIO2 to low ( GND )
toogle EN 1-2 time
then bootloader must come, right?

flashing the empty flash ic
with posted esptool

then boot ap demo
connected GND,
connect 3.3,
toggle 1-2 EN to 3.3 ( have we no Rest Pin? )
GPIO0 to high ( 3.3 )

right?
till later, will try it now in few minits.
best wishes

It sounds like rudi has the same issue as me - the ESP32 (ESP31B?) acts deaf in flash download mode.

EDIT:
Update - I see continuity between breakout pin 34 and ESP31 pin 37, which is listed in the specifications as U0RXD (page 13, "Figure 2-2. ESP31 (Beta Version) Pin Layout"). Pad 37 seems connected to the QFN package - the fillet looks the same as every other one (very good).

FWIW, I get 'boot mode 11' here when I go into flash mode... (which works). I will take a look at my bootstrap pin setup when I have time.

will check this evening again, why i can't go in bootmode 11 and upload the files.

sry for big files, perhabs admin can convert to small file.
i upload for see the output in original.

best wishes
rudi ;-)

btw:
done!
;-)
but i cant upload firmware, why, this must be clear at evening.
bye...

@bienvenue
try to deconnect the TX/RX to the USB if you reconnect the modul

@Jer.. think we have a monday breakout :)
btw if you have a second or a reserve.... perhabs you can add me nexttime to a new list.
will try at evening again. so long.

What did you do to get it to work, specifically? (The "little test and patching".)

I'm using the esptool32.py uploaded by rojer9 and it works all ok, both under Linux and Windows.
There is no esp_init_data_default.bin found in the SDK but I guess it is not important for the moment.

hi bienvenu, sry for wrote name wrong before,

i "massacred" the modul :lol:

i picked it out from [EDIT right word, EDIT add Picture of ] breadboard,
IMG_4486s.JPG
IMG_4486s.JPG (44.53 KiB) Viewed 6048 times
bobbed in into again, and same again, same again,one time then the app was boot, so i stopped this. Soldering Modul on Breakout was ok,but think the U0TXD makes worse ( see 8digit toogle switch table 1-2, the U0TXD on boot SPI is High Level )then i connect gpio0 to low, deconnect EN from high (3.3) this wire was very sensitive then and allways reset boot, then connect this to the EN ( 3.3) again, then was boot mode (13)

@thanks faye for declare boot log http://esp32.com/viewtopic.php?f=16&p=216#p216

but can't upload a new firmware.
( have record with desktop video, will upload for not listed view, and post the link under document folder in forum then , there are more processes to see.)

after try to update with esptool, same position, power off, power on, there is no app boot or no boot mode. so i bobbed it again. i am sure, the special breadboard is top, but will make a fix PCB for the evening and try again. i suspected the U0TXD, will attempt at evening to solder switch with pullup/pulldown and other. the usb TTL stick do not separate properly if you deconnect the board from power, the pins are Rear supply via the USB ( Rx, Tx ) if you power of the modul. (seeks a path through the USB)

btw:

in ESP32 RTOS SDK 1.0 github is declare blank.bin

blank.bin--------->0xfe000(for 1MB SPI Flash)

and in Getting Started after Table 2.2 under point 7 "upload files" is it declare with

blank.bin--------->0xFC000

read the command well, in the last config the command is flashing -fs 2m
that means, that there is use a 2Mbit flash in example,
we have 1 Mbit flash in ESP318 so 0xfe000 is the right.

read carefull Table 2-4 for blank.bin

btw:
the modul are not stocked in

R5
R6
C14
R3

the schematics declare
R5 ~~~~ NC GPIO32
R6 ~~~~ NC GPIO33
C14 --||-- NC GND
R3 ~~~~ NC VDD33

so i think, have no component lost :D

best wishes
rudi ;-)

edit: at evening will do next try.
