  • Use AST2400 (older) or AST2600 (newer) public datasheets as a reference – similar architecture but different registers.
  • Reverse engineer from existing open-source hardware designs (e.g., Raptor Computing Talos II schematics).
  • Study Linux kernel drivers: drivers/soc/aspeed/ and drivers/tty/serial/8250/8250_aspeed_vuart.c

Part 3: Technical Specifications (From the New Datasheet)

  • LPC/eSPI timing diagrams – for host-to-BMC mailbox channels
  • KCS (Keyboard Controller Style) interface – used for IPMI messaging
  • Shared memory region – for VGA framebuffer access
