Launch the following 88command as root: 89 90 dd if=./output/images/sdcard.img of=/dev/<your-microsd-device> 91 92*** WARNING! The script will destroy all the card content. Use with care! *** 93 94For details about the medium image layout, see the definition in 95board/freescale/common/imx/genimage.cfg.template. 96 97Boot the SABRE board 98==================== 99 100i.MX6 SABRE SD 101-------------- 102 103To boot your newly created system on an i.MX6 SABRE SD Board (refer to 104the i.MX6 SABRE SD Quick Start Guide for guidance): 105- insert the SD card in the SD3 slot of the board; 106- locate the BOOT dip switches (SW6), set dips 2 and 7 to ON, all others to OFF; 107- connect a Micro USB cable to Debug Port and connect using a terminal emulator 108 at 115200 bps, 8n1; 109- power on the board. 110 111i.MX6 SoloX SABRE SD 112-------------------- 113 114To boot your newly created system on an i.MX6 SoloX SABRE SD Board 115(refer to the i.MX6 SoloX SABRE SD Quick Start Guide for guidance): 116- insert the SD card in the J4-SD4 socket at the bottom of the board; 117- Set the SW10, SW11 and SW12 DIP switches at the top of the board in 118 their default position, to boot from SD card. Reference configuration: 119 120 SW10 121 1 2 3 4 5 6 7 8 122 off off off off off off off off 123 124 SW11 125 1 2 3 4 5 6 7 8 126 off off ON ON ON off off off 127 128 SW12 129 1 2 3 4 5 6 7 8 130 off ON off off off off off off 131 132- connect a Micro USB cable to the J16 Debug Port at the bottom of the 133 board. This is a dual UART debug port; connect to the first tty using 134 a terminal emulator at 115200 bps, 8n1; 135- power on the board with the SW1-PWR switch at the top of the board. 136 137SABRE Auto 138---------- 139 140To boot your newly created system on a SABRE Auto Board (refer to the SABRE for 141Automotive Infotainment Quick Start Guide for guidance): 142- insert the SD card in the CPU card SD card socket J14; 143- Set the S1, S2 and S3 DIP switches and J3 jumper to boot from SD on CPU card. 144 Reference configuration: 145 146 S1 147 1 2 3 4 5 6 7 8 9 10 148 off ON off off ON off off off off off 149 150 S2 151 1 2 3 4 152 off off ON off 153 154 S3 155 1 2 3 4 156 off off ON ON 157 158 J3: 1-2 159 160- connect an RS-232 UART cable to CPU card debug port J18 UART DB9 and 161 connect using a terminal emulator at 115200 bps, 8n1; 162- power on the board. 163 164Enjoy! 165 166References 167========== 168 169https://community.freescale.com/docs/DOC-95015 170https://community.freescale.com/docs/DOC-95017 171https://community.freescale.com/docs/DOC-99218 172
