SPI flash interposer that filters writes, verifies firmware images before boot and restores a recovery image on corruption.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| host_spi | in | parallel | 6 | |
| flash_spi | out | parallel | 6 |
