Having problem burning bootloader to custom Atmega328p board
-
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.

Hi team,
Any one have experience in Altium schematic designing.
I am facing some issue in Hierarchy->harness in Schematic.
The offpage number for harness is not showing, and while generation the smart PDF if we click the harness port /green box the page want to go there automatically, but that also not working. -
Hi @dipu_varghese ,
Here is the sample input from the binary edge impulse inference,
Predictions (DSP: 16 ms., Classification: 1 ms., Anomaly: 2 ms.): idle: 0.91016 snake: 0.08203 updown: 0.00391 wave: 0.00391 anomaly score: -0.067”And from here for example we can try to get the updown values only by attaching the device to another controller and read the Serial string directly.
void setup() { // Start serial communication at 9600 baud Serial.begin(9600); } void loop() { // Wait until there is data available on the serial port while (!Serial.available()) { // Do nothing } // Read the input string from the serial port String inputString = Serial.readStringUntil('\n'); // Find the position of the "updown" value in the input string int updownPos = inputString.indexOf("updown:"); // If the "updown" value was found in the input string if (updownPos >= 0) { // Extract the "updown" value from the input string String updownString = inputString.substring(updownPos + 8, inputString.indexOf('\n', updownPos)); // Convert the "updown" value to a float float updownValue = updownString.toFloat(); // Output the "updown" value Serial.println(updownValue); } }The sketch should then output the "updown" value, which is 0.08203.
Hope this will be helpful, let me know if you need more clarification.
