Boot Modes
By default the TE-0729 supports QSPI-Flash-Memory, JTAG and SD-Card (if available on base board) boot modes.
The boot modes are controlled by the Pins 'BOOT1' and 'BOOT2' on the board to board (B2B) connector.
Pin-State 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.
| Signal | B2B Pin |
|---|---|
| TCK | J2: 119 |
| TDI | J2: 115 |
| TDO | J2: 117 |
| TMS | J2: 113 |
JTAGSEL pin in J2 should be kept low or grounded for normal operation.
