ESP32 Forum

I have some code that was running successfully on an ESP32-S3-MINI-1
Today I've received the latest set of PCBA's which now have an ESP32-S3-WROOM-1 and more memory

I've modified the code to match the new GPIO configuration and it compiles and downloads to the ESP32 which boots fine.
However it constantly resetting with versions of the following

I (509) app_start: Starting
ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x15 (USB_UART_CHIP_RESET),boot:0x8 (SPI_FAST_FLASH_BOOT)
Saved PC:0x4200a463


Any suggestions on where I need to look to either pin this down to a problem with the hardware / PCB layout or the code?

Thanks

Problem solved.
Larger capacitor needed on the 3.3V rail near the ESP32.
New PCBA's have a different 3.3V power supply that wasn't able to handle the power surge when the ESP32 turned on the WiFi
