Does the SAMW25 SOC on MKR1000 has bootloader

Hardware MKR Family MKR1000

Hello Friends, If I get a new SOC SAMW25 the one used in MKR1000 do I need to burn a bootloader onto it just like ATmega328 has to be fired with bootloader before programming it with Arduino IDE. If the SOC needs to burn a bootloader how this can be done

Yes, of course - all Arduinos have a bootloader to make programming possible without an additional "programmer" tool.

You need the SAMW25 SWDIO and SWCLK pins. On the MKR1000 PC board they are, together with reset and VCC/GND, connected to a 10pin programming port (J3, lower left in the MKR1000 schematic). You should be able to program the bootloader with a proper programming tool like the Segger J-Link.

On this page:

you find some more info about how to program a bootloader (in this case the feather-M0 one, which uses the same SAMD21 processor).

Thanks michael,

Can I bootload my new SOC ATSAMW25 with arduino IDE just like I bootload ATMEGA328 using arduino UNO. If so what procedure should I follow.

Thanks in advance
