Flash:
The size of the main block is device dependent. The largest size available is 32 kB (32 pages). The information block has 1024 bytes available for user data. The information block also contains chip configuration data located in a reserved area. The main block is mapped to address 0x00000000 and the information block is mapped to address 0x0FE00000. All Flash memory is organized into 1024 byte pages.

2 Bootloader
2.1 UART Bootloader
EFM32 出厂自带 UART bootloader
拉高 DBG_SWCLK 通电启动 EFM32 Series 0, EZR32 Series 0, or EFM32 Series 1 即可进入 Uart Bootloader:
- The bootloader will check the application space in flash.
- If the application space contains a valid application, the bootloader will run that application.
- If there is not a valid application present, the bootloader will sleep in EM2 to conserve power, while periodically checking the bootloader pins.
Note: DBG_SWCLK has an internal pull-down. Leaving this pin unconnected will not invoke bootloader mode on reset.
EFM32ZG110 Pin:
- PIN19 --- PF0 --- DBG_SWCLK / BOOT_TX -----> Serial_RX
- PIN20 --- PF1 --- DBG_SWDIO / BOOT_RX -----> Serial_TX
Once the bootloader has been successfully initialized it will print the bootloader version and chip unique ID:
1.40 ChipID: F08AB6000B153525
2.2 ToBoot
USB DFU bootloader - "toboot"

3 Flash Tools
3.1 Overview
EFM32 的刷写和调试协议规范:AN0062 Programming Internal Flash Over SWDI
刷写硬件官方推荐 SEGGER 公司的 J-Link,EFM32 开发板都集成了。。。配套使用官方工具 Commander (JLinkARM.dll)
也可以使用 STLINK V2,配套使用 OpenOCD。。。
3.2 OpenOCD
Build OpenOCD in Windows https://elinux.org/Compiling_OpenOCD_Win7
1. Download and install setup-x86.exe (32-bit system)
2. 选择 Install from Internet, 在 "User URL" 处输入以下地址:
https://mirrors.tuna.tsinghua.edu.cn/cygwin/
点击 Add 按钮, 然后选中 https://mirrors.tuna.tsinghua.edu.cn, 点击”下一步”进行安装。
3. 选择如下软件包:
autobuild autoconf autoconf-archive automake libtool make pkg-config git patchutils ################ mingw64-i686-binutils mingw64-i686-gcc-core mingw64-i686-pthreads mingw64-i686-runtime mingw64-i686-libusb 1.0 ################
运行环境如果是 cygwin(不推荐) 则把如上相关包换成:
gcc-core libusb1.0 libusb1.0-devel usbutils
4. git clone
$ git clone git://git.code.sf.net/p/openocd/code openocd $ cd openocd $ mkdir build $ cd build $ ../configure --enable-ftdi --enable-stlink --disable-doxygen-html --disable-werror --disable-libtool-lock --build=i686-pc-cygwin --host=i686-w64-mingw32 $ make $ make install
编译完后,找到 libgcc_s_sjlj-1.dll libusb-1.0.dll openocd.exe 置于: dist/bin/ 下,usr/local/share/openocd 放在 dist/share 下,打包 dist/ 即可 release 到其他机器运行
You can flash the bin file into the EFM32 via OpenOCD with STLINK V2:
Pin:
- PIN19 --- PF0 --- DBG_SWCLK -----> STLINK_V2-SWCLK
- PIN20 --- PF1 --- DBG_SWDIO -----> STLINK_V2-SWDIO
- PIN-7 --- RSTn --- RESET ---> STLINK_V2-Reset

3.3 Commander
Simplicity Commander is the Silabs official tool. It is invoked using a simple Command Line Interface (CLI).
- Flash their own applications.
- Configure their own applications.
- Create binaries for production.
Simplicity Commander is designed to support the Silicon Labs Wireless STK and STK platforms
By default in Studio v4, Simplicity Commander can be found at the following path:
C:\SiliconLabs\SimplicityStudio\v4\developer\adapter_packs\commander\commander.exe

5 Tomu
5.1 QuickStart
5.2 Basic
- 刷入一个 Bootloader --- toboot
- 使用 dfu-utils 从 USB 口刷入固件程序...
- arduino core: https://github.com/huaweiwx/ARDUINO_EFM32
5.3 Flashing the toboot
Brand-new EFM32HG will not have Toboot installed. Instead, they might have the SiLabs AN0042 bootloader.
The recommend way to load the bootloader onto a Chip is using a Raspberry Pi with OpenOCD. Instructions for doing this can be found in the openocd directory. You need OpenOCD version 0.10.0 or later to have EFM32HG support.
Tomu can be powered using the 3.3V pin, so you can create a sort of "programming wand" by bringing 3.3V, GND, SCK, and SIO out to a 0.1" header, running openocd in a loop, and touching the programming pins on the side of a Tomu board. The process only takes a few seconds, so contact doesn't have to be great.
5.4 Install dfu-util
The dfu-util suite of programs is used to talk to Toboot
Ubuntu and Debian
sudo apt-get install dfu-util
Create /etc/udev/rules.d/10-tomu.rules and populate it with the following:
ATTRS{idProduct}=="70b1", ATTRS{idVendor}=="1209", MODE="777" (Note: you can give it a more restrictive mode if you also give it a group that you’re in)
Windows
Download dfu-util-static.exe from the dfu-util repository and rename it to dfu-util.exe. Place it somewhere in your $PATH for convenience. To build examples, you’ll also want to get dfu-suffix.exe and put it in your $PATH.
Mac
Install Homebrew and run:
brew install dfu-util
6 Low Power
6.1 Energy Mode
- EM0 (Run Mode): 114 µA/MHz; All peripherals can be active
- EM1 (Sleep Mode): 48 µA/MHz; All peripherals, including DMA, PRS and memory system, are still available
- EM2 (Deep Sleep Mode): 0.9 µA; High-Frequency Oscillator is turned off, 32.768 kHz oscillator running, selected low energy peripherals (RTC, PCNT, LEUART, I2C, WDOG and ACMP) are still available. RTC, Power-on Reset, Brown-out Detection and full RAM and CPU retention is also included.
- EM3 (Stop Mode): 0.5 µA; Low-Frequency Oscillator is disabled, but there is still full CPU and RAM retention, as well as Power-on Reset, Pin reset, EM4 wake-up and Brown-out Detection. The low-power ACMP, asynchronous external interrupt, PCNT, and I2C can wake-up the device
- EM4 (Shutoff Mode): 20nA; Pin reset, GPIO pin wake-up, GPIO pin retention and the PowerOn Reset are available. All pins are put into their reset state.

8 User Data Flash
All members of the EFM32 family provide a single page of flash memory for storing "user" data.
It is located at address: 0x0FE0 0000 on all devices
Device User Page Size(words) User Page Size(bytes) Gecko 128 512 Giant Gecko 1024 4096 Tiny Gecko 128 512 Wonder Gecko 512 2048 Leopard Gecko 512 2048 Zero Gecko 256 1024 Pearl Gecko 512 2048 Jade Gecko 512 2048
Examples:
#define USERDATA_BASE (0x0FE00000UL) /**< User data page base address */ #define USERDATA ((uint32_t *) USERDATA_BASE) uint32_t a = USERDATA[0]; uint32_t b = USERDATA[1]; uint32_t * userDataPage = USERDATA; uint32_t userData[] = { 0x01020304, 0x05060708 }; MSC_Init(); //must be called prior to any Flash write or erase operation. MSC_ErasePage(userDataPage); MSC_WriteWord(userDataPage, userData, sizeof(userData));
