Help uploading to esp32

Projects General Guidance
1

Hi
I just got a esp32 with a oled screen. I tried to upload the u8g2 Littlerookchess sketch, but then i get the error below. I aklso tried the terminal sketch, and same error. It compiles and uploads fine, but then i see this in the Serial monitor, and it keeps spamming.

10:57:23.926 -> rst:0x8 (TG1WDT_SYS_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
10:57:23.926 -> configsip: 0, SPIWP:0xee

10:57:23.926 -> mode:DIO, clock div:1
10:57:23.926 -> load:0x3fff0030,len:1344
10:57:23.926 -> load:0x40078000,len:13964
10:57:23.926 -> load:0x40080400,len:3600
10:57:23.926 -> entry 0x400805f0

Thanks, hacker128

One of us is confused.

3

Maybe it's a memory shortage problem. Try to optimise the code or use an updated version of the ESP32 with a larger memory size.

4

what is the specific ESP32 module?
what have you selected under Tools>Board? I tend to use ESP32 Dev module for general ESP32-WROOM-32 modules

to get more information in the Arduino IDE select File>Preferences and enable "Verbose output during Compiling and upload" then attempt to compile and upload your program again
if there are still problems upload the error messages as text (not a screen image)

5

Yes but i tried the terminal sketch on a esp8266 which is WEAKER than my current esp32

6

yes i use Esp-wroom-32 and use esp32 dev module too.

7

does a simple program such as blink compile, load and run OK?
if not remove all external devices from the ESP32 and try again??

8

Yes sketches like blink and other sketches work fine. Its just terminal and Littlerookchess.

9

Yes maybe. I probably should choose Huge APP(3MBno-ota)? I just realized im using default.
But then get this error
