Boot Loader
Responsible for the power-on boot-up process, the non-changeable boot code resides in
the boot ROM. At power-on, the boot ROM reads the boot mode register to determine the
boot mode. The boot mode is user-configurable.
User-Configurable Boot Modes
The user can select one of these boot sources to configure the boot mode:
• SD Card
• Nand flash
• NOR flash
• Quad-SPI flash
• JTAG: No boot source, this mode is used for non-secure debugging
Note:
NAND/NOR flashes are not available on the ZC702 board.
This TRD uses SD card boot mode for booting. For details on pin and jumper configuration
for SD boot, see the Zynq-7000 All Programmable SoC: ZC702 Evaluation Kit and Video and
