Hi all,

Same for me. I can't flash modules with M4N4 while the others work just fine. I have sent a message to Espressif and hope that they come up with a solution.

Found the issue, it was in the code of the STM32: the data returned from the ESP module was not send back to the pc. Case closed.

Strapping is working fine, for now I use RTS and CTS to enter the bootloader, the module replies: "ESP-ROM:esp32c3-api1-20210207...." which proves that the bootloader starts. Flash program tool sends: C0 00 08 24 00 00 00 00 00 07 07 12 20, 32 times 55, C0 Module replies: C0 01 08 04 00 07 07 12 20 ...

Hello, I have my own board which contains a ESP32-C3-Mini. The schematic is an exact copy of the evaluation kit. On my board I have a STM32 which is connected to the ESP through the serial line. This micro also contains a usb to cdc driver (which we have used in the past with Wroom and Wrover module...

Hi, We have done our own design. The JTAG connects only with TMS, TCK, TDI and TDO. The reset is not connected to the programmer. Just power the WROOM and start debugging. Please be careful, I had to program the WROOM first through the serial line before the JTAG was usable. I have entered a questio...

Hi all,

I have noticed that I can't program an empty WROOM with JTAG. I have to program the module through the bootloader once to activate the JTAG usage. Is there a way to use JTAG also for first time programming? We really need this for production.

Thanks,
André

Hi,

I have been struggling with debugging until I found "VisualGDB embedded". This is a plugin for Visual Studio which really works out of the box! Also "menuconfig" is now done from within Visual Studio just by editing the project properties. It is really worth its low price!

Hi, do you use all the latest versions? Like openocd 20191114? I also tried version 20190313, same result. Here is the openocd board config: # BEA OpenOCD configuration file for ESP32-WROOM on RPU board. # # It uses a JLINK cable # # For example, OpenOCD can be started for ESP32 debugging on # # ope...

Hi, I am working on my own board. The code, letting a led blink, is working, the led blinks. The tools, all latest version, are running on Ubuntu (virtual machine) under Visual Studio Code. Compiling and programming works fine but I am already busy for two weeks trying to get the debugging working. ...
