I dont know what happened. After a while working fine in my project, I try to upload an updated sketch... and keep getting errors:

Arduino: 1.8.19 (Windows 10), Placa:"Thinary Nano Every, ATMEGA328"

avrdude: jtagmkII_initialize(): Cannot locate "flash" and "boot" memories in description

avrdude: verification error, first mismatch at byte 0x0001

     0x72 != 0x94

avrdude: verification error; content mismatch

no one even replied for this, i get the same error.. somehow pathetic that they sold Nano Every boards and failed to provide basic sketch upload features....I CANT EVEN LOAD my first Nano Every Program

Have you looked in the NANO EVERY section itself ?
Did you install the board cores ?

OP uses a non-standard board so it's just the luck of the game if somebody (with experience with the board) sees it and tries to help.

Yes Bob, thanks for ur reply, in the meanwhile with a little bit of debug, I found that my program is actually loaded, and the message is just to be ignored.... Thanks
