starting a thread @KoGames

light cedar Aug 21, 2025, 1:43 PM

#

ok im here

smoky stump Aug 21, 2025, 1:43 PM

#

ok, so put it in bootloader mode, check the port in Device Manager, and try chip-id again

light cedar Aug 21, 2025, 1:44 PM

#

ok so in the otg port im going to run bootloader

smoky stump Aug 21, 2025, 1:44 PM

#

no, with COM14

#

don't change the USB for this

light cedar Aug 21, 2025, 1:44 PM

#

ah well with tlg if i hold boot and pres reset it wont open a usb device

smoky stump Aug 21, 2025, 1:45 PM

#

leave it plugged into TTL. hold down BOOT, press reset, release RESET, release boot

light cedar Aug 21, 2025, 1:45 PM

#

ok

#

i did it

smoky stump Aug 21, 2025, 1:45 PM

#

so no COM port?

light cedar Aug 21, 2025, 1:45 PM

#

#

its still 14

smoky stump Aug 21, 2025, 1:46 PM

#

that's ok, but don't reset it agian, and try chip-id

light cedar Aug 21, 2025, 1:46 PM

#

same thing

#

maybe its somethign to do with something inside circuit python

#

i mean when i use the web circuit python instaler everything instals ok

smoky stump Aug 21, 2025, 1:48 PM

#

are you using OTG or TTL with the web installer?

light cedar Aug 21, 2025, 1:49 PM

#

im trying both

#

but otg

#

is usualy the one that works

toxic hill Aug 21, 2025, 1:51 PM

#

why would an s3 have a usb-serial bridge?

smoky stump Aug 21, 2025, 1:51 PM

#

some dev boards have one so you can do debugging

#

hence two USB jacks

toxic hill Aug 21, 2025, 1:52 PM

#

different pins than USB peripheral?

smoky stump Aug 21, 2025, 1:52 PM

#

yes, connected to TXD0 and RXD0 via a usb-serial chip

toxic hill Aug 21, 2025, 1:52 PM

#

maybe "OTG" is the S3 USB periph?

smoky stump Aug 21, 2025, 1:52 PM

#

I think so

#

esp since TTL says CH340, which is the USB-serial chip

toxic hill Aug 21, 2025, 1:53 PM

#

so connect to that one (OTG), and then BOOT/RESET

#

maybe?

smoky stump Aug 21, 2025, 1:53 PM

#

either works for me for chip-id

#

@light cedar do you have Mu open or anything else at all?

light cedar Aug 21, 2025, 1:54 PM

#

whats mu

smoky stump Aug 21, 2025, 1:54 PM

#

ok, then you don't 🙂

light cedar Aug 21, 2025, 1:54 PM

#

all i got open is uhh

#

toxic hill Aug 21, 2025, 1:54 PM

#

^^ yah. just close everything (arduino etc) but command line prompt for running esptool

smoky stump Aug 21, 2025, 1:54 PM

#

you have thonny open

light cedar Aug 21, 2025, 1:54 PM

#

i closed it now

#

so now i jave

#

smoky stump Aug 21, 2025, 1:56 PM

#

close these too, not sure what some of them are:

light cedar Aug 21, 2025, 1:56 PM

#

theyre closed

#

only chrome discoard and device manager is open

#

and on chrome theres nothing connected to the esp32 s3

#

at this point i think my esp32 is forever cursed with circuit python

smoky stump Aug 21, 2025, 2:01 PM

#

looking at https://docs.espressif.com/projects/esptool/en/latest/esp32s3/advanced-topics/boot-mode-selection.html#manual-bootloader another suggestion is to hold down BOOT, press and release RESET, and then keeping holding down boot, and run esptool.py

#

this is if the board has wonky choices on its pins

light cedar Aug 21, 2025, 2:02 PM

#

ok but do i do the boot sequence on uhh

#

otlg or ttl

smoky stump Aug 21, 2025, 2:02 PM

#

try TTL first, then OTG

light cedar Aug 21, 2025, 2:02 PM

#

ok

smoky stump Aug 21, 2025, 2:03 PM

#

I know the board was cheap, but it's at the expense of your time. There is no proper documentation for the board

with ttl

smoky stump Aug 21, 2025, 2:05 PM

#

make sure you are not getting the BOOT and RESET buttons mixed up

light cedar Aug 21, 2025, 2:06 PM

#

im not

#

also heres wit otg C:\Users\KoGam>esptool --port COM24 chip-id
esptool v5.0.2
Serial port COM24:
Connecting.............

A serial exception error occurred: Write timeout
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.

#

are you sure i can do anything with the code or smth like that

smoky stump Aug 21, 2025, 2:12 PM

#

looking....

light cedar Aug 21, 2025, 2:12 PM

#

ohmyfk god

#

i think i found the problem

#

the esp32 was on a breadboard the whole time

#

with a st7796s screen

#

i removed the esp32 now the circuit python instaler is able to connect to the esp32

#

so removing it defently did something

#

YES

#

#

the screen whas the problem

smoky stump Aug 21, 2025, 2:15 PM

#

excellent - don't connect anything to GPIO0 or GPIO46. There's an object lesson. Always disconnect what you can, when debugging.

light cedar Aug 21, 2025, 2:15 PM

#

ok yes finnaly

#

arduino now runs on the board

#

thank you so much for helping

smoky stump Aug 21, 2025, 2:15 PM

#

you're welcome

light cedar Aug 21, 2025, 2:16 PM

#

i still learned a lot from this

#

im defently coming back to this server to help others when i can

#

but now i have to finish my phone project 👍
