atmega328PB upload bootloader problem

[tonynyny]

Hello. I need help to program an atmega328PB stick on a custom PCB. So an empty atmega328PB.

I search for many days, but nothing, I can't program this *** board ^^

So to do this, I use an UNO as ISP (sketch uploaded in), link it to the 328PB (mosi, miso, etc), select on the arduino IDE the "ATMEGA328PB" given by the minicore package.
After hitting "burn bootloader, I get this error :

avrdude done. Thank you.

Failed chip erase: uploading error: exit status 1

I tried to use AVRDUDESS for doing that, but same error.

I don't know what to do now... after few days of research... It seems that the 328PB is not responding to the UNO (response 0x000000)

I wish I can learn the 328pb fuse, but I don't know how to do it

Can we really program an atmega328PB with arduino uno as ISP ? Is it only programmer like usbtinyusb which can do that ?

Do you have a crystal on your PCB?

[tonynyny]

yes

DTR goes to FT232RNL

[tonynyny]

yes also
