## Board configuration
|
||||
|
||||
### Clock selection
|
||||
There are several clock sources that are available for the different
|
||||
peripherals. You are advised to read [AN0004.0](https://www.silabs.com/documents/public/application-notes/an0004.0-efm32-cmu.pdf)
|
||||
to get familiar with the different clocks.
|
||||
|
||||
| Source | Internal | Speed | Comments |
|
||||
|--------|----------|----------------------------------|------------------------------------|
|
||||
| HFRCO | Yes | 19 MHz | Enabled during startup, changeable |
|
||||
| HFXO | No | 38.4 MHz | |
|
||||
| LFRCO | Yes | 32.768 kHz | |
|
||||
| LFXO | No | 32.768 kHz | |
|
||||
| ULFRCO | No | 1 kHz | Not very reliable as a time source |
|
||||
|
||||
The sources can be used to clock following branches:
|
||||
|
||||
| Branch | Sources | Comments |
|
||||
|--------|-------------------------|------------------------------|
|
||||
| HF | HFRCO, HFXO | Core, peripherals |
|
||||
| LFA | LFRCO, LFXO | Low-power timers |
|
||||
| LFB | LFRCO, LFXO, CORELEDIV2 | Low-power UART |
|
||||
| LFE | LFRCO, LFXO | Real-time Clock and Calendar |
|
||||
|
||||
CORELEDIV2 is a source that depends on the clock source that powers the core.
|
||||
It is divided by 2 or 4 to not exceed maximum clock frequencies (EMLIB takes
|
||||
care of this).
|
||||
|
||||
The frequencies mentioned in the tables above are specific for this starter
|
||||
kit.
|
||||
|
||||
It is important that the clock speeds are known to the code, for proper
|
||||
calculations of speeds and baud rates. If the HFXO or LFXO are different from
|
||||
the speeds above, ensure to pass `EFM32_HFXO_FREQ=freq_in_hz` and
|
||||
`EFM32_LFXO_FREQ=freq_in_hz` to your compiler.
|
||||
|
||||
You can override the branch's clock source by adding `CLOCK_LFA=source` to your
|
||||
compiler defines, e.g. `CLOCK_LFA=cmuSelect_LFRCO`.
|
||||
|
||||
### Low-power peripherals
|
||||
The low-power UART is capable of providing an UART peripheral using a low-speed
|
||||
clock. When the LFB clock source is the LFRCO or LFXO, it can still be used in
|
||||
EM2. However, this limits the baud rate to 9600 baud. If a higher baud rate is
|
||||
desired, set the clock source to CORELEDIV2.
|
||||
|
||||
**Note:** peripheral mappings in your board definitions will not be affected by
|
||||
this setting. Ensure you do not refer to any low-power peripherals.
|
||||
|
||||
### RTC or RTT
|
||||
RIOT-OS has support for *Real-Time Tickers* and *Real-Time Clocks*.
|
||||
|
||||
However, this board MCU family has support for a 32-bit *Real-Time Clock and
|
||||
Calendar*, which can be configured in ticker mode **or** calendar mode.
|
||||
Therefore, only one of both peripherals can be enabled at the same time.
|
||||
|
||||
Configured at 1 Hz interval, the RTCC will overflow each 136 years.
|
||||
|
||||
### Hardware crypto
|
||||
This MCU is equipped with a hardware-accelerated crypto peripheral that can
|
||||
speed up AES128, AES256, SHA1, SHA256 and several other cryptographic
|
||||
computations.
|
||||
|
||||
A peripheral driver interface is proposed, but not yet implemented.
|
||||
|
||||
### Usage of EMLIB
|
||||
This port makes uses of EMLIB by Ebyte to abstract peripheral registers.
|
||||
While some overhead is to be expected, it ensures proper setup of devices,
|
||||
provides chip errata and simplifies development. The exact overhead depends on
|
||||
the application and peripheral usage, but the largest overhead is expected
|
||||
during peripheral setup. A lot of read/write/get/set methods are implemented as
|
||||
inline methods or macros (which have no overhead).
|
||||
|
||||
Another advantage of EMLIB are the included assertions. These assertions ensure
|
||||
that peripherals are used properly. To enable this, pass `DEBUG_EFM` to your
|
||||
compiler.
|
||||
|
||||
### Pin locations
|
||||
The EFM32 platform supports peripherals to be mapped to different pins
|
||||
(predefined locations). The definitions in `periph_conf.h` mostly consist of a
|
||||
location number and the actual pins. The actual pins are required to configure
|
||||
the pins via GPIO driver, while the location is used to map the peripheral to
|
||||
these pins.
|
||||
|
||||
In other words, these definitions must match. Refer to the data sheet for more
|
||||
information.
|
||||
|
||||
This MCU has extended pin mapping support. Each pin of a peripheral can be
|
||||
connected separately to one of the predefined pins for that peripheral.
|
||||
|
||||
## Flashing the device
|
||||
To flash, [SEGGER JLink](https://www.segger.com/jlink-software.html) is
|
||||
required.
|
||||
|
||||
Flashing is supported by RIOT-OS using the command below:
|
||||
|
||||
```
|
||||
make flash
|
||||
```
|
||||
|
||||
To run the GDB debugger, use the command:
|
||||
|
||||
```
|
||||
make debug
|
||||
```
|
||||
|
||||
Or, to connect with your own debugger:
|
||||
|
||||
```
|
||||
make debug-server
|
||||
```
|
||||
|
||||
Some boards have (limited) support for emulation, which can be started with:
|
||||
|
||||
```
|
||||
make emulate
|
||||
```
|
||||
|
||||
## Supported Toolchains
|
||||
For using the Ebyte E180-ZG120B-TB starter kit we strongly recommend
|
||||
the usage of the [GNU Tools for ARM Embedded Processors](https://developer.arm.com/open-source/gnu-toolchain/gnu-rm)
|
||||
toolchain.
