UNABLE TO PROGRAM MY ESP CHIP USING AN EXTERNAL PROGRAMMER

Lakshmidivija commented 5 months ago

Board

ESP-32 ALL KITS

Device Description

i am using esp-32-wroom-32e ic on my pcb board. in order to code my ic i recently bought a esp-prog v1.1 . i connected all the pins exactly how they are on programmer . but when i am trying to upload the code my boot button on my programmer is not responding despite giving connections properly.

Hardware Configuration

i am writing uart code where rx is on gpio 28 and tx is on gpio 6

Version

latest development Release Candidate (RC-X)

IDE Name

arduino

Operating System

windows 11 pro

Flash frequency

80

PSRAM enabled

no

Upload speed

921600

Description

boot button is not working even after giving connections. i connected 3v3,gnd,tx to rx pin on ic , rx to tx pin, enable pin and io0. i tried programming while connecting all these and also i connected only vcc , gnd,rx and tx and check same issue. also checked continuity for the boot button with multimeter . its working fine. supply is also working fine. both power led and tx pin led on esp prog are in on condition while uploading. i would like to know the solution hhow to upload code when boot button is not working

Sketch

#define RXD0 28
#define TXD0 6

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
   Serial1.begin(115200, SERIAL_8N1, RXD0, TXD0);
}

void loop() {
  // put your main code here, to run repeatedly:
  if (Serial.available() > 0) {
    char incomingChar = Serial.read();
    Serial.println("Received: ");
    Serial.println(incomingChar);
  }  

}

Debug Message

no

Please show diagram on all connections between your ESP32 and the Prog

ESP-Prog might show as two serial ports. In that case, you will need to upload to the second one (first one is JTAG). The only connections you need is RX, TX, IO0, EN, GND and 3v3. RX and TX are the original GPIOs 1 and 3, not your custom selected ones.

first you said ESP32-Wroom, now ESP32-S3-Wroom. Which is it? And which numbers are you saying you are using? the ones inside the module (1-40) or the ones outside (Actual GPIO names).


ESP-Prog | ESP32-S3
-------------------
IO0      |      IO0
EN       |       EN
RXD      |     TXD0
TXD      |     RXD0
GND      |      GND
3V3      |      3V3
