Page 5: Installation And Getting Started
Before using the serial bootloader with a PC host, there are some steps to follow: Unpack the package to a folder on the PC hard drive. Connect the PL360G55Cx-EK board to the PC via one of the serial interfaces supported by the embedded serial bootloader, UART or USB. -

By default, the embedded serial bootloader supports USART4 peripheral of the SAMG55J19 which is accessible in the TXD, RXD and GND pins of the mikroBUS connector in the PL360G55Cx-EK boards. It is the responsibility of the user to ensure a proper connection to the host device. - Page 7 The size of the application binary file used in this example is 152658 bytes (0x25452). Type S20010000,25452# in your terminal window. The prompt automatically goes down to the next line signaling that it is waiting for the file transfer process.

- Page 8 Installation and Getting Started Send the application binary file to the SAMG55J19 in binary format. For using the UART interface, it is required to select XMODEM-CRC protocol to transfer the binary file: User Guide DS50002878A-page 8 © 2019 Microchip Technology Inc.
- Page 9 When the upload process is complete, the prompt appears again. Type command G# in the terminal window to start the application. 10. If the loaded application is running in the SAMG55J19, remove the jumper PROG (J2) and reset the board. User Guide DS50002878A-page 9 © 2019 Microchip Technology Inc.

JTAG adapter (for example, Atmel-ICE SAM-ICE ) 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. - Page 12 Appendix B: How to Flash the Serial Bootloader ... In the GPNVM Bits tab, enable the check of the bit GPNVMBITS.BOOT_MODE and press the Program button. Now the bootloader binary is loaded and running in the SAMG55J19.
