Warning for eMMC variant of the MicroSoM
|
|
========================================
|
|
|
|
If you bought a MicroSoM version that includes an on-board eMMC flash, the
|
|
built-in microSD card slot *WILL NOT WORK*. The Internet says that you have to
|
|
upload the first bootloader via UART. This manual does not cover these steps;
|
|
only MicroSoMs without the eMMC are supported.
|
|
|
|
Build
|
|
=====
|
|
|
|
Start with the default Buildroot's configuration for Clearfog:
|
|
|
|
make solidrun_clearfog_defconfig
|
|
|
|
Build all components:
|
|
|
|
make
|
|
|
|
The results of the build are available in ./output/images.
|
|
|
|
Create a bootable SD card
|
|
=========================
|
|
|
|
To determine the device associated to the SD card have a look in the
|
|
/proc/partitions file:
|
|
|
|
cat /proc/partitions
|
|
|
|
Buildroot prepares a bootable "sdcard.img" image in the output/images/
|
|
directory, ready to be dumped on a microSD card. Launch the following
|
|
command as root:
|
|
|
|
dd if=output/images/sdcard.img of=/dev/<your-microsd-device> conv=fdatasync
|
|
|
|
*** WARNING! The dd command will destroy all the card content. Use with care! ***
|
|
|
|
For details about the medium image layout, see the definition in
|
|
board/solidrun/clearfog/genimage.cfg.
|
|
|
|
Boot the Clearfog board
|
|
=======================
|
|
|
|
Here's how to boot the board:
|
|
|
|
- Set up the DIP switches for microSD boot. The correct values are:
|
|
1: off, 2: off, 3: ON, 4: ON, 5: ON. In this scheme, switch #1" is closer to
|
|
the ethernet ports and #5 is closer to the microSD card, "ON" means towards
|
|
the SOM, and "off" means towards the SFP cage.
|
|
- Connect to the board's console over the microUSB port.
|
|
- Insert the SD card into the slot on the board (pins up).
|
|
- Power up the board.
