| 127 | | If your primary boot won't boot for some reason (ie, you corrupted it during development) you can boot from a microSD (see [#bootdevice here]). |
| 128 | | |
| 129 | | To create a bootable microSD meant for recovery purposes only needing the Bootloader you can use [http://dev.gateworks.com/newport/boot_firmware/firmware-newport.img firmware-newport.img]: |
| 130 | | * On a Linux host: |
| 131 | | {{{#!bash |
| 132 | | DEVICE=/dev/sdc # set to the microSD on your host |
| 133 | | sudo dd if=firmware-newport.img of=$DEVICE |
| 134 | | }}} |
| 135 | | - '''Be careful to set the DEVICE above to the device the microSD appears as on your Linux host - you do not want to overwrite part of your hosts filesystem''' |
| 136 | | * On a Newport board booted from eMMC from U-Boot: |
| 137 | | {{{#!bash |
| 138 | | mmc list # if booted from eMMC you should see microSD as dev 1 |
| 139 | | mmc dev 1 # select microSD |
| 140 | | tftpboot ${loadaddr} firmware-newport.img && mmc write ${loadaddr} 0 8000 |
| 141 | | }}} |
