29 These configurations will use AT91Bootstrap, u-boot and a linux kernel from
34 - ALSA tools to test audio
35 - FFMPEG to record video from the ISI/ISC
36 - I2C, SPI, CAN, etc. tools
37 - modetest for LCD screens, HDMI
38 - Wilc1000/Wilc3000 firmware for the Atmel Wireless sdio module
39 - SSH for convenience
40 - GDB/GDB server for debug
51 assumes the system will be flashed on NAND. In this case, after
53 using SAM-BA" section below.

63 Flashing the board
64 ------------------
66 Connect the board:
67  o at91sam9g45m10ek: DBGU: J10, USB sam-ba: J14
68  o at91sam9rlek: DBGU: J19, USB sam-ba: J21
69  o at91sam9x5ek: DBGU: J11, USB sam-ba: J20
70  o sama5d3xek: DBGU: J14, USB sam-ba: J20
71  o sama5d3 Xplained: DBGU: J23, USB sam-ba: J6
72  o sama5d4ek: DBGU: J22 or J24, USB sam-ba: J1
73  o sama5d4 Xplained: DBGU: J1, USB sam-ba: J11
75 Start the board in RomBOOT:
78     2. start the board
82    1. J11 on 1-2 (BMS=1), open J12 and J13
83    2. start the board
88       - Cogent: open *NCS jumper
89       - Embest: open SW1
90       - Ronetix: open J1 and J2
91    2. start the board
93       - Cogent: close *NCS jumper
94       - Embest: close SW1 (ON position)
95       - Ronetix: close J1 and J2
98    1. start the board
105    2. start the board
109    1. start the board
116    2. start the board
119 "RomBOOT" should appear on your console (this should be ttyUSBx or ttyACMx)
121 Now locate the USB sam-ba interface it should be ttyACMx, usually ttyACM0
122 dmesg on your machine should give:
123 usb 1-2.1.4: New USB device found, idVendor=03eb, idProduct=6124
124 usb 1-2.1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0
125 cdc_acm 1-2.1.4:1.0: ttyACM0: USB ACM device
129 You can then flash the board using the provided flasher.sh script in board/atmel:
131 board/atmel/flasher.sh <builddir_path> <interface> <board>
135 board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained
146 You need at least a 1GB SD card. All the data on the SD card will be
147 lost. To copy the image on the SD card:
149 /!\ Caution be sure to do it on the right mmcblk device /!\
153 Insert your SD card in your Xplained/Evaluation Kit board, and
154 enjoy. The default U-Boot environment will load properly the kernel
159 u-boot, the kernel image and all dtb variants for your board. The dtb

168 update your u-boot environment:

179 take a look at the the genimage.cfg file in the board directory.
