MikroTik CRS305-1G-4S+IN
========================
CRS305-1G-4S+IN is a 4x SFP+ switch with a Gigabit Ethernet port for management.
Specifications:
- Marvell Prestera 98DX3236 switch with an integrated ARMv7 CPU
- 512 MB DDR3 RAM
- UART @ 115200bps
- 4x SFP+
- Gigabit Ethernet (AR8033)
- 16 MB SPI flash (Winbond 25Q128JVSM)
Currently supported hardware:
- UART boot (using kwboot) and console
- SPI boot, environment and load kernel
Planned:
- Gigabit Ethernet support
Getting binary.0
================
binary.0 (DDR3 init phase) can be retrieved/extracted from the integrated bootloader on the SPI flash.
Then binary.0 can be replaced with the extracted blob.
