What the Acorn check tests

• The Acorn check: what the check is, what it does to the card, and what it can show.

• Acorn tests and their wires on a Raspberry Pi 5: the wires each test uses on a Pi 5.

• Acorn tests and their wires on a Compute Blade: the wires each test uses on a blade.

• The Acorn DDR memory test: how the check tests the card’s memory.

• The Acorn Wishbone bridges test: how the check reaches the design’s registers.

• JTAG loads and the PCIe endpoint: why the endpoint is detached, and why a blade needs its serial port off.
