+## Vorago VA416x0
+
+Tested on VA41620 and VA41630 MCU's.
+
+MCU: Cortex-M4 with Triple-Mode Redundancy (TMR) RAD hardening at up to 100MHz.
+FLASH: The VA41630 has 256KB of internal SPI FRAM (for the VA41620 its external). FRAM is Infineon FM25V20A.
+SRAM: 64KB on-chip SRAM and 256KB on-chip program memory
+
+Boot ROM loads at 20MHz from SPI bus to internal data SRAM
+
+### Building Vorago VA416x0
+
+All build settings come from .config file. For this platform use `TARGET=va416x0`.
+See example configuration at `config/examples/vorago_va416x0.config`.

+### Flashing Vorago VA416x0
+
+Flash using Segger JLink: `JLinkExe -CommanderScript tools/scripts/flash_va416xx.jlink`
+
+Example JLink flash script `tools/scripts/flash_va416xx.jlink`:
+
+```
+device VA416XX
+si 1
+speed 2000
+r
+h
+write4 0x40010010 0x1
+loadbin factory.bin 0x0
+write4 0x40010010 0x0
+loadfile ../VA416xx_SDK/loader.elf
+exit
+```
+
+The `loader.elf` programs the external SPI FRAM with the IRAM image. It is created with `make loader` from the SDK.
+
+Example boot ouput on UART 0 (MCU TX):
+
+```

+### Debugging Vorago VA416x0
+
+Start the GDB server: `JLinkGDBServer -device VA416XX -if SWD -speed 2000 -port 3333`
+
+Run: `arm-none-eabi-gdb`. This will source the `.gdbinit` to load symbols for `wolfboot.elf` and `test-app/image.elf`. It will also attempt to connect to the GDB server on default port 3333.
+
+### Testing updates on VA416x0
+
+Note: This test was run with DEBUG=1 and DEBUG_UART=1 to generate logging on the UART.
+
+See `tools/scripts/vorago/build_test_update.sh`:
+
+```sh
