ESP32 : Reset loop

[antonins]

Hello all,
I've got an issue with one of my ESP32 board.


After running several hours, the wifi disappear. When I have a look on serial activity, I've got this reset loop :

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:2

I try to download the program again, to flahs the ESP32 but still the same issue.

Do you know what could be the cause of this loop ?

Thanks for your feedback

Hello,

More information about this issue.

I find that if the flash upload in QOUT mode ESP32 WROOM works perfectly. If I reupload the program with DIO, reset loop occur again.

I've got several board with this issue.

Anyone have an idea of what happen ?

Thanks for your help,
Antonin

What specific board hardware is this? If it's custom, do you have schematics / board layout files?

Hello ESP-SPRITE,

my ESP32 board is a ESP32-WROOM-32E-N8

I have several IC working well with this esp32, but IC with the new program have this issue.

If I removed ESP32 from the IC and sold a new one with an old program, everything works fine.
