Multi-source boot controller
Maturity plannedTargets FPGA + ASICDifficulty MediumPriority 2
Boot sequencer that selects among serial flash, eMMC, UART and USB recovery sources by strap or fuse and loads the first-stage image into SRAM.
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 |
| boot_strap | in | parallel | 4 |
