WiFi Kit 32 v2 - Corrupt serial output

#1

Hi all

I’m using a WiFi Kit 32 v2 with the Arduino IDE.

Whatever I do the serial output comes through corrupted:

rst:0x1 (POWERON_RESET),boot:0x17 (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:1
load:0x3fff0030,len:1256
load:0x40078000,len:13832
load:0x40080400,len:4
load:0x40080404,len:3048
entry 0x40080590

As you can see the bootloader shows up correctly and everything after is unreadable.

This is the code I’m testing with:

void setup() {
  Serial.begin(115200);
}

void loop() {
  delay(1000);
  Serial.println("test");
}

The serial monitor is set to 115200 baud rate, I’ve also tried many other combinations.

Any advice appreciated.

Perhaps choose to replace the connecting cable

Can the development environment be shared?

#4

I tried a replacement cable, it didn’t help.

I get the same corrupt output on an M1 Macbook and a Desktop running Windows 11. I’m running the latest Arduino IDE. Let me know if you need any further information

I can see the serial output if the baudrate is set to 74880 in the monitor. The baudrate is set to 115200 in the sketch…
