Can't programm 328PB via TTL anymore after burning bootloader

alxwhte · January 16, 2024, 3:41pm

Hi,

so i have a A-Star 328PB with a USB AVR Programmer v2.1 in Arduino IDE.
It all worked perfectly well until i burned a new bootloader on the board. Now its not possible to programm the 328PB via TTL anymore

For burning the bootloader i used Minicore with the following settings:

Did i used some wrong settings?

If i want to upload a blank Sketch i get the following error message:

Sketch uses 1084 bytes (3%) of program storage space. Maximum is 32384 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

I already tried different Baud rates.

Hello.

Instead of using Minicore, can you try burning the original bootloader back onto your A-Star by following the instructions in “The A-Star 328PB Serial Bootloader” section of the A-Star 328PB user’s guide?

If you try that procedure and continue having trouble programming, could you post the new error message from your IDE, a screenshot of the programmer’s configuration utility software after a programming attempt, and some pictures that show all of your connections? Also, please try to confirm whether the bootloader is on the microcontroller. As described in the user’s guide section I mentioned before, you can reset the A-Star (e.g. by pressing the reset button) and look for three quick flashes of the yellow LED performed by the bootloader, followed by a second of inactivity with the LED off.

Hi Patrick,

first of all: Thanks for your Answer!

I tried the Pololu Bootloader before and the same error occur, but i can post all the detail here. This is the error i get after trying to programm the Pololu 328PB via TTL after burning the bootloader:

For burning the bootloader i use the following settings:
