Burn bootloader while NRF24L01 is connected
-
I think I have distroyed many ATmega328p when I am trying to burn bootloader to it while NRF24L01 is connected to ATmega, both are using MISO, MOSI and SCK.
Can anyone confirm my thoughts?
-
No, uselly you have "Enable" pin with pullup
-
So they are not distroyed?
But I cant upload new bootloader when NRF is connected the ATmega always answer
avrdude: Device signature = 0x000000 avrdude: Yikes! Invalid device signature.
I remove the NRF and still answer
avrdude: Device signature = 0x000000 avrdude: Yikes! Invalid device signature.

check ou have pullup resistor on CSN. Or you can try to remove NRF24 and try to burn bootloader.

See above: I get same answer when NRF is removed

I don't know why your atmega isn't responding but it's not related to programming when NRF is connected.
Can you check the fuse ? Is it work with new atmega you ISP hardware is ok ?

I am using Arsuino UNO as ISP.I will try to find a way to read fuses or maybe it is writing when I use AVRdude manually

I tried with new atmega, it worked fine, so I tried with new atmega and NRF connected, worked fine. So I can be sure that the problem was/is not the NRF, as @Fabien said, thanks.
I don't understand what it can be, I have destroyed maybe 5 pieces when I try to upload new sketch, through Arduino UNO as ISP, maybe it can be power problem or maybe the wires got loosen when I upload sketch?
