Appendix B: How to Flash the Serial Bootloader Binary
If the serial embedded bootloader is not present in the SAMG55J19 device or it needs to be upgraded,
connect a JTAG adapter (for example,
) to the JTAG connector (J7) in the
PL360G55Cx-EK board and then program the SAMG55J19 with the binary image (.bin) of the embedded
bootloader via the JTAG interface.
Attention:
To use the ARM
®
Multi-ICE or Atmel SAM-ICE, a JTAG adapter for 20 to 10 pins is
necessary.
The pre-compiled binary image of the embedded serial bootloader included in the firmware package is
located in the folder:
\sam\application\serial_bootloader\bin\
To Flash the bootloader binary using an Atmel-ICE and Atmel Studio 7, follow these steps:
1.
Connect Atmel-ICE to the JTAG interface of the PL360G55Cx-EK board and power up the board.
2.
Launch Atmel Studio 7 and open the
Device Programming
window (Menu Tools/Device
Programming).
3.
In the comboxes, select the tool
Atmel-ICE
, device
ATSAMG55J19
and interface
JTAG
. The
communication with the microcontroller can be checked reading the device signature.
4.
In the
Memories
tab, select the binary file of the serial bootloader to Flash and press the
Program
button.
