SiLabs EFM32 Gecko
|
|
------------------
|
|
|
|
This is a port for the Silicon Laboratories' EFM32
|
|
*Gecko* family. Board support is available for the following:
|
|
|
|
#. **SiLabs EFM32 Gecko Starter Kit (EFM32-G8XX-STK)**. The Gecko
|
|
Starter Kit features:
|
|
|
|
- EFM32G890F128 MCU with 128 kB flash and 16 kB RAM
|
|
- 32.768 kHz crystal (LXFO) and 32 MHz crystal (HXFO)
|
|
- Advanced Energy Monitoring
|
|
- Touch slider
|
|
- 4x40 LCD
|
|
- 4 User LEDs
|
|
- 2 pushbutton switches
|
|
- Reset button and a switch to disconnect the battery.
|
|
- On-board SEGGER J-Link USB emulator
|
|
- ARM 20 pin JTAG/SWD standard Debug in/out connector
|
|
|
|
**STATUS**. The basic port is verified and available now. This
|
|
includes on-board LED and button support and a serial console
|
|
available on LEUART0. A single configuration is available using the
|
|
NuttShell NSH and the LEUART0 serial console. DMA and USART-based SPI
|
|
supported are included, but not fully tested.

|
|
|
|
**STATUS**. The board support is complete but untested because of
|
|
tool-related issues. An OpenOCD compatible, SWD debugger would be
|
|
required to make further progress in testing.

**STATUS**.
|
|
|
|
- The basic board support for the *Giant Gecko* was introduced int
|
|
the NuttX source tree in NuttX-7.6. A verified configuration was
|
|
available for the basic NuttShell (NSH) using LEUART0 for the
|
|
serial console.
|
|
- Development of USB support is in started, but never completed.
|
|
- Reset Management Unit (RMU) was added Pierre-noel Bouteville in
