Zynq 7000 remote bring-up

Brief overview of the bring-up of an unprogrammed Zynq 7000 board using remote labgrid infrastructure.

Prerequisites

Zynq 7000 board with serial console, controllable boot mode pins (JTAG and QSPI modes), Ethernet access.
JTAG.
labgrid remote infrastructure.
Xilinx tools (program_flash).
Binaries for Zynq: boot.bin (FSBL, U-Boot), minimalistic FIT (Linux, DTB, rootfs) for QSPI to flash eMMC, final FIT for eMMC.
Custom strategy to handle boot modes, transitions to minimalistic FIT, etc.

Process

The transitions are handled using the labgrid strategy.

Power off the board, switch the board to JTAG mode.
Power on the board, flash boot.bin, and minimalistic FIT to QSPI (using program_flash).
Power off the board, switch the board to QSPI mode.
Transition to minimalistic FIT (e.g., it controls U-Boot and logs in).
Transfer the final FIT via Ethernet to the board. Flash the binary into eMMC.
Transition to the final Linux. Run the (py)tests to verify that the board is correctly flashed.
