Flash issue ESP32-PICO-MINI-02

Postby reza_neam » Fri Sep 16, 2022 8:24 pm

Hello,
I recently switched from TTGO-Micro32-v2 to ESP32-PICO-MINI-02
But I can't make it work and can't troubleshoot the source of the issue!

When I connect the MCU to PC (USB-bridge) in terminal MCU endlessly prints this

Code: Select all

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
invalid header: 0xffffffff
After burning a very simple code (I use PlatformIO), I get slighly different error as follows

Code: Select all

rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 271414342, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:1
load:0x3fff0030,len:1184
load:0x40078000,len:12812
load:0x40080400,len:3032
entry 0x400805e4
When I try to erase the flash, it seems everything is working just fine!

Code: Select all
