System boot and recovery via microSD card
BELK provides a bootable microSD that can be used not only to
quickly start the system, but also as a recovery method in case
the primary boot device (eg. SPI NOR flash) gets erased or
corrupted. The following sections describe how to create a
bootable SD card and how to configure the system for booting
from SD.
3.4.8.1 How to create a bootable MicroSD card
This section describes how to create a new bootable microSD
card from scratch.
The following components must be available:
●
FSBL built with Vivado 2014.4 as described in Section
●
U-boot built in elf format, as described in Section
●
FPGA bitstream (optional)
The procedure is the following:
●
from the Vivado 2014.4 SDK, apply the required patches to the
main.c
project file.This step can be done in two ways:
manually, directly modifying the
main.c
file
adding the following code snippets:
