Unable to upload.

Hello,

I'm new to the ESP32. I am struggling to upload any to the Nano32. My setup is a Windows 10 laptop. I'm using esp-idf version 1. When trying to the chip, I get the following information :

Code: Select all

$ make flash

A fatal error occurred: Timed out waiting for packet header
make: *** [C:/esp32idf/esp-idf/components/esptool_py/Makefile.projbuild:48: flash] Error 2

Hopefully, someone maybe able to help me. Thank you in advance,

Hi Beb,

It looks like it's mostly working and then something is interrupting the connection.

- If you change the default baud rate (under "make menuconfig", Serial Port Flashing Settings) to 115200, does anything change?

- Is it possible some other software running on your computer may be trying to access the USB serial port?

- If you change USB ports or use a different USB cable, does anything change?

Hi,

Thanks for the reply.

I still cant upload. Tried changing to 115200, turning off my virus scanner, changed my usb cable, and still no joy. I will carrying on hoping to succeed in uploading.

Do you have a different computer you can try it on? It may be you have faulty hardware.

Also IIRC on Windows you may need to press "Boot" button before uploading and hold it until the upload starts.

Thank you all for the help.

Ive reached a point with the nano32 where I can upload some code, but get a MD5 error.

However, Ive now also got a node32s, where there is no issue with uploading code, all works fine on this one. So either my nano32 doesnt work, or there is something else wrong.

Thanks

Beb
