Re: ESP32-D2WD Issue SW RESET issue.( Code flash done but not work as expect)

Thanks, As I check I am not able to find out any ESP32-D2WD SOIC based reference design Even I am not able to find any ESP32-WROOM or WROOVER module inside that ESP32-D2WD Used. Can you help me to find out the Document for ESP32-D2WD SOIC based reference design Or any tested hardware which shows a 1...

Re: ESP32-D2WD Issue SW RESET issue.( Code flash done but not work as expect)

Hey, Thank you. What is the step if I would like to go with the internal Flash of ESP32-D2WD? I order ESP32-D0WD and check it But need time to deliver Chip. I want to run that board withESP32-D2WD I (I already test:- remove external flash and try to upload code but the board does not except ESP32-D2...

Re: ESP32-D2WD Issue SW RESET issue.( Code flash done but not work as expect)

I don't think the issue is we use an external flash. We already try the design without EEPROM a month ago and we got an issue that can not upload/Flash chip so based on the forum we got the solution to add external EEPROM. Also, have you check as per Espressrif reference design document page 10 (2.3...

ESP32-D2WD Issue SW RESET issue.( Code flash done but not work as expect)

Dear, Please find below the Schematic connection of the ESP32-D2WD SOIC based custom board design. I use the ESPProg UART flash method to flash code. I am successfully able to detect chips as well as able to flash a code using Arduino IDE. But My issue is code does not run except what we write. I go...

ESP32 Dev Module Antenna comparison.

Hello, We design ESP32-Module based application and As i check there is number of ESP32 Module in market. Our requirement is max WiFi signal strength. As we check ESP-WROOM-32 Module have PCB Trace antenna / ESP-WROOM-32U Have U.FL Socket / ESP-WROVER-I have U.FL Socket and PCB trace antenna. May I ...

Re: ESP32-D2WD SOIC Uisng Custom board design.

Ok Thanks, So no need any JTAG to upload a code I can flash ESP32-D2WD using UART directly even its custom board and Fresh chip. Also can I use BOOT and RST button of ESP-Prog Flasher instead of place over custom board?? ESP32-Prog BOOT and RST button connect with ESP32-D2WD pin of BOOT and RST by U...

ESP32-D2WD SOIC Uisng Custom board design.

Hello, 1)We design ESP32-D2WD chip based custom board and for flash code we use ESP32-Prog UART method. Our confusion is ESP32-D2WD Fresh chip consist UART Bootloader ?? Or we need to add JTAG as well over board and first we need to Upload bootloader using JTAG over Fresh ESP32-D2WD SOIC then we can...

Re: ESP32-D2WD Based Custom board JTAG Flash issue.

Hey, I already Change adapter_khz Frequency lower value as well as done all process which is suggested but still, I am not getting success. Can anyone confirm is that hardware issue or some issue with setup OpenOCD tool. We use ESP32-D2WD IC and use openocd -f board/esp32-wrover-kit-3.3v.cfg command...
