FLASH MEMORY PROGRAMMING
The board is preprogrammed with a Linux image that includes an Ethernet driver and
evaluation code. Users may reprogram the on-board flash memory via the micro-AB
USB port (USB port A). The latest Linux image can be found in the product page of the
board on the Microchip website. For on-board flash memory and SD card programming
instructions, refer to
Appendix A. “Programming the SAMA5D3 EDS Board”
. The
J20 jumper must be installed to enable the on-board flash memory for programming.
However, when reprogramming an already programmed board, it may be necessary to
follow these steps:
1. Remove the J20 jumper (this prevents the MCU from booting from the on-board
flash memory).
2. Power on the board
3. Install the J20 jumper (This enables the flash memory for programming.)
4. Program the on-board flash memory.
