Boot Modes
TE0729 supports primary boot from
- JTAG
- SPI Flash
- SD Card
Boot from on-board eMMC is also supported as secondary boot (FSBL must be loaded from SPI Flash).
The boot modes are controlled by the Pins 'BOOT1' and 'BOOT2' on the board to board (B2B) connector.
BOOTMODE1 | BOOTMODE2 | Boot mode |
---|---|---|
LOW | LOW | |
LOW | HIGH | |
HIGH | LOW | |
HIGH | HIGH |
JTAG
JTAG access to the Xilinx Zynq-7000 device is provided by connector J2.
