Flash storage for FPGA images on the T2 card is implemented in dual-QSPI mode (8 bits). The following signals comprise this interface:
- Chip selects
Additional details are as follows:
- The dual-QSPI mode flash has been implemented with two 2 Gb SPI NOR flash devices (Micron MT25QU02GCBB8E12-0AAT).
- The MT25QU02GCBB8E12-0AAT NOR flash devices are automotive grade for thermal design reasons.
- The flash storage supports a user image and a fallback image.
- The T2 card is shipped with a fallback image that cannot be overwritten (the password is kept with Xilinx manufacturing).
