ESP32 S3 N16R8 not running program

Postby millet » Mon Jun 24, 2024 2:27 pm

Hi,

I created custom PCB with ESP32 S3 N16R8. I have on PCB C2102N USB-to-Serial. I am managing to enter boot mode and flashing device successfully using Arduino IDE, however after reseting chip nothing happens, seems my chip is stuck somewhere. I purchased chip from DigiKey so it should be okay, board except ESP32 S3 soldered by JLCPCB. ESP32 S3 soldered by me.

If I disconnect and reconnect board after flashing I am able to get this serial output:

Code: Select all

ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x1 (POWERON),boot:0x29 (SPI_FAST_FLASH_BOOT)
SPIWP:0xee
mode:DIO, clock div:1
load:0x3fce3808,len:0x44c
load:0x403c9700,len:0xbd8
load:0x403cc700,len:0x2a80
entry 0x403c98d0
ESP
I attached my circuit schematic for ESP32 S3. Just in case attached also flash settings.

I would apprieceate help to get chip working. I spent over $100 for PCB assembly :/

If anything, I think you're missing an RC network on the EN pin.
