Your custom PCB should have a reset circuit, usually a resistor to Vcc and a capacitor to ground, on the EN input. Do you have that?
Thanks for your answer. Yes I have both

Reset signal from ESP-Prog board

Hi all, I have an ESP32 on a custom PCB, and I use this board to program the ESP - I hooked the ESP-Prog board to my PCB with wires: https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/308/Intro_to_the_ESP-Prog_Brd_Web.pdf?_gl=1*1n0mvai*_up*MQ..&gclid=Cj0KCQjwltKxBhDMARIsAG8KnqWS-axgojX5Rcj...

ESP32 switching programming to regular working mode and error

Hi, I'm having issues with changing operating modes of an ESP32 chip. Some details: I'm using Arduino IDE, and I want to program the ESP32 and run it with my code. For now I'm using a very simple code that just prints to serial. I have access to the GPIO0 and GPIO2 and I can also manually connect th...

Increase SPI speed on ESP32 (sample rate, not CLK)

Hi, I'm using the SPI on an ESP32 chip. I need to read a stream of data on the ESP SPI master at 2MS/s, each sample is 1 byte. So I have 2 Mbytes each second. For now I'm using a for loop that reads x amount of samples, I have 16MHz SPI CLK which is enough, the problem is that there is a delay betwe...

VSCode Extension installation fails barely at step 5

Hi, I'm following this https://github.com/espressif/vscode-esp-idf-extension/blob/master/docs/tutorial/install.md at step 5, when I do ESP-IDF: Configure ESP-IDF extension >> Install, it fails with error 404: File download response error: Failed web connection with error code: 404 https://github.com...

assert failed: taskSelectHighestPriorityTaskSMP tasks.c:3447 (xTaskScheduled == pdTRUE)

Hi all, I'm writing a code for the ESP32 in Arduino IDE with C++ objects defined in C++ files. The code works like this, it configures an interrupt on a pin of the ESP32 and when it receives the interrupt, it reads a message on the SPI as master and then it prints the message to serial. 1) I had ESP...

Re: Pin #25 - GPIO16 doesn't work on ESP32-PICO-D4

Even though the datasheet says "Notice:", I didn't notice that! :D Thank you

Pin #25 - GPIO16 doesn't work on ESP32-PICO-D4

Hi, I have an ESP32-PICO-D4 chip and a very simple Arduino that toggles its pins using digitalWrite(pin, HIGH/LOW); I can toggle different pins, no problem, but specifically pin no.25 which the datasheet reports as Name: IO16 Functions: GPIO16, HS1_DATA4, U2RXD, EMAC_CLK_OUT doesn't work. Any ideas ...

TinyPico suspend BLE callback

Hi all, I have a TinyPico board which has an ESP32. In my Arduino code I have a class that defines the callback onWrite to read Bluetooth messages. class MyCallbacks: public BLECharacteristicCallbacks { // on received bluetooth message void onWrite(BLECharacteristic *pCharacteristic) { ... } } Then ...
