Hi @Anwaarullah

Thank you for the code file . I am facing an issue if you can help me .

i have followed the link as mentioned below in your youtube channel .Which was about the ESP-IDF

https://www.youtube.com/watch?v=Lc6ausiKvQM

At the end of doing all the steps i am able to install and compile the "blink" project provided in examples .

But the issue i faced is that when i downloaded in to my esp32-c3 board . I got the following error as attached image file .

After that i followed your full video . And when i made changes in "Target.cmake" file as mentioned by you and compile the " blink "project. Then i got the following error .

Thanks in Advance for your help!

Thank you so much ! for your support and wonderful job! when i followed your video then i am able to see

I (121355) example: Turning the LED ON!
I (122355) example: Turning the LED OFF!
I (123355) example: Turning the LED ON!
I (124355) example: Turning the LED OFF!

Sorry ! it was my mistake ,i selected ESP-IDF version 4.2 . it must be selected master (development board ) .

thanks Again !

Best Regards !

Thanks for sharing what caused the issue and how you solved it.

Hi @Anwaarullah Again !

Led Blink Example worked well ! But when i compiled the "Hello_World" then it gives the following error

Can you please help me in this regard ?

Hi, @Anwaarullah Again!

Need your help, as I mentioned at the start of this post that issue was resolved. After 2 months of working ESP-IDF stop working by generating errors. So I have to reinstall the esp-IDF and espressif tools. But unfortunately, esp32_c3 reboots again and again with the same error as mentioned at the start of the post. Can you help me in this regard?
