Having problem burning bootloader to custom Atmega328p board

[kowshik1729]

Hi all,

I have made a custom board with Atmega328P SMD IC and now I am having a problem flashing it. I have flashed multiple chips like these earlier, however this time I am having a hard time figuring out the issue.

I am using Arduino UNO as an ISP programmer to burn bootloader but getting responses like Attempt 1 of 10 - stk500() is not responding etc., like that. I need some help regarding this issue.

Any kind of help will be greatly appreciated. Please ask me for any additional information that I might have not mentioned in this post.

Thanks in advance.

@kowshik1729 Did you double-checked the ISP Pins connection? I also faced similar issue because of cold solder joints. also if possible can you share the ICSP connection diagram and the methods you used to flash!

@salmanfaris I am using Arduino UNO as ISP programmer.(General ISP connections are made). I used both Arduino IDE and also avrdude command line to burn the bootloader. I am sharing link to pictures and debug outputs I got on both avrdude and arduino here. Please check it and let me know if it rings any bells for you.
