Got the avrdude stk500 error after bad testing from my part

[john_wick]

Hello.

I am doing a project for a class I'm taking and the teacher asked us to do it in Bare Metal programming in C. That means using only native C functions and libraries and deal with registers directly.

So, I was doing some tests with the avr-gcc compiler and the avrdude command line and I think I bricked my Arduino!

When I was using this code, everything was working fine:

Code: [Select]

$ avr-gcc -Os -DF_CPU=16000000UL -mmcu=atmega328p -c -o test.o test.c
$ avr-gcc -mmcu=atmega328p test.o -o test
$ avr-objcopy -O ihex -R .eeprom test test.hex
$ avrdude -F -V -c arduino -p ATMEGA328P -P /dev/ttyACM0 -b 115200 -U flash:w:test.hex

Just to be clear, I used this kit with both Arduino IDE and avr-gcc plus avrdude several times with sucess, so I know exactly the event that caused this error.

Then, I tried this out and avrdude output was regular as usual, but after this I'm having problems uploading with both Arduino IDE and avrdude.

Code: [Select]

$ avr-gcc -Os -c -o test.o test.c
$ avr-gcc test.o -o test
$ avr-objcopy -O ihex -R .eeprom test test.hex
$ avrdude -F -V -c arduino -p ATMEGA328P -P /dev/ttyACM0 -b 115200 -U flash:w:test.hex

After that, I did a loopback test and everything I typed did echoed back.

Just to sum it up:

- Operating system: Ubuntu 16.04
- Board: Arduino UNO with ATMEGA328P-PU
- I was able to upload to the board before.
- The error message from Arduino IDE:

avrdude done.  Thank you.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

- The test.c code (although I know it's not the code because it uploaded without error before):
I was going to post the code here, but it was exceeding the character limit.

That's it!

Thank you very much!

Try re loading the bootloader  via the icsp* port and then run a simple example program as a test


* I keep getting the name of this wrong ( doh)

Thank you. I will do that and post here the outcome.

Will take some time because I never done it before, but I'm looking it up.
