VAB-820 supports two booting ways. One is from Micro SD storage card and
the other is SPI ROM. This section will guide users through making the Linux
system boot media for VAB-820.
Users could use the image built from BSP, its location is mentioned in the
previous Section 3.3, or use the demo image in EVK/
EVK/ EVK/
EVK/ folder of VAB-820 HMI
Solution Pack.
4.1 Booting from Micro SD card
The Micro SD card image provides the full system to boot with U-Boot and
kernel.
If users setup the U-boot parameter for the first time, users need to boot from
the Micro SD card. Set the J11 jumper setting (refer to Figure 1 and Table 3) to
boot from the Micro SD.
