Hello,
I recently switched from TTGO-Micro32-v2 to ESP32-PICO-MINI-02
But I can’t make it work; basically, I can’t run any code on the chip!
Most likely it is not anything to do with PlatformIO
When I connect the MCU to the PC (USB bridge) in the terminal MCU endlessly prints this
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 slightly different errors as follows
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!

Erasing flash (this may take a while)...

Could you please help me to find out what would be wrong?
