+Flashing the NAND using SAM-BA
+==============================
+
+This document explains how to flash a basic Buildroot system on various
+Atmel boards. Additional details can
+also be found on the Linux4SAM website, in particular here:
+http://www.at91.com/linux4sam/bin/view/Linux4SAM/GettingStarted
+
+This guide covers the following configurations:
+ - at91sam9g45m10ek_defconfig
+ - at91sam9rlek_defconfig
+ - at91sam9x5ek_defconfig (at91sam9g15, at91sam9g25, at91sam9x25,
+ at91sam9g35 and at91sam9x35)
+ - atmel_sama5d3xek_defconfig (sama5d31, sama5d33, sama5d34, sama5d35,
+ sama5d36)
+ - atmel_sama5d3_xplained_defconfig
+ - atmel_sama5d4ek_defconfig
+ - atmel_sama5d4_xplained_defconfig
+
+These configurations will use AT91Bootstrap, u-boot and a linux kernel from
+the git trees maintained by Atmel. They also build u-boot SPL when
+available, it can replace AT91Bootstrap.

+
+Flashing the board
+------------------
+
+Connect the board:
+ o at91sam9g45m10ek: DBGU: J10, USB sam-ba: J14
+ o at91sam9rlek: DBGU: J19, USB sam-ba: J21
+ o at91sam9x5ek: DBGU: J11, USB sam-ba: J20
+ o sama5d3xek: DBGU: J14, USB sam-ba: J20
+ o sama5d3 Xplained: DBGU: J23, USB sam-ba: J6
+ o sama5d4ek: DBGU: J22 or J24, USB sam-ba: J1
+ o sama5d4 Xplained: DBGU: J1, USB sam-ba: J11
+
+Start the board in RomBOOT:
+ o at91sam9g45m10ek:
+ 1. open JP8, JP10 and JP12
+ 2. start the board
+ 3. close JP8, JP10 and JP12
+
+ o at91sam9rlek:
+ 1. J11 on 1-2 (BMS=1), open J12 and J13
+ 2. start the board
+ 3. close J12 and J13
+
+ o at91sam9x5ek:
+ 1. open JP9 and:
+ - Cogent: open *NCS jumper
+ - Embest: open SW1
+ - Ronetix: open J1 and J2
+ 2. start the board
+ 3. close JP9 and:
+ - Cogent: close *NCS jumper
+ - Embest: close SW1 (ON position)
+ - Ronetix: close J1 and J2
+
+ o sama5d3xek:
+ 1. start the board
+ 2. push BP4 and BP1
+ 3. release BP1
+ 4. release BP4
+
+ o sama5d3 Xplained:
+ 1. open JP5 (NANDCS) and JP6 (SPICS)
+ 2. start the board
+ 3. close JP5 ans JP6
+
+ o sama5d4ek:
+ 1. start the board
+ 2. push BP3 and BP4
+ 3. release BP4
+ 4. release BP3
+
+ o sama5d4 Xplained:
+ 1. close JP7 (BOOT_DIS)
+ 2. start the board
+ 3. open JP7
+
+"RomBOOT" should appear on your console (this should be ttyUSBx or ttyACMx)

+Now locate the USB sam-ba interface it should be ttyACMx, usually ttyACM0
+dmesg on your machine should give:
+usb 1-2.1.4: New USB device found, idVendor=03eb, idProduct=6124
+usb 1-2.1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0
+cdc_acm 1-2.1.4:1.0: ttyACM0: USB ACM device
+
+Look for idVendor=03eb, idProduct=6124, this is the interface you want to use.
+
+You can then flash the board using the provided flasher.sh script in board/atmel:
+
+board/atmel/flasher.sh <builddir_path> <interface> <board>
+
+For example, for an out of tree build made in
+/tmp/atmel_sama5d3_xplained/ for the sama5d3 Xplained, you would use:
+board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained
+
+Reboot, the system should boot up to the buildroot login invite.
