UART Ranges
For the NXP-SCCK, UART variables have ranges as follows.
Baud
Variable: uart.baud
Range: minimum: 194 maximum: 12750000 (12.75 Mbit/s)
Example
Set UART1 baud to 2,000,000:
uart.baud 1 2000000 rawData
Variable: uart.data
Range: 5 - 8
Example
Set UART1 to 8 bits
uart.data 1 8Flow
Variable: uart.flow
- UART0: No flow control - value is
off/0only - UART1: Flow control available - values are
off/0oron/1
Example
uart.flow 1 onZentriOS SDK
The ZentriOS SDK supports the NXP-SCCK.
Connecting the NXP-SCCK For Use with the ZentriOS SDK
Insert the Zentri MMW001 SD card into the SD socket on the LPC General Purpose shield.
For USB connections, use the cables supplied in the kit or other high quality USB cables.
First connect a USB cable between a USB port on the SDK computer and the NXP-SCCK J5 USB port.
For extra power, connect a USB cable from a USB power supply, such as a computer USB port, to the CN11 USB port on the LPC General Purpose shield.
SDK Memory Size and Availability
The table shows memory availability for ZentriOS-WZ-3.2+.
| Memory Type | ZAP Requirement | Size | Available Size | Comments |
|---|---|---|---|---|
| Internal flash | ZAP code and Read Only data | 1Mbyte | 512K | A zap image may fill the entire flash bank B. |
| RAM | ZAP global Read/Write data | 136K | ~30K | Use malloc() to dynamically allocate from HEAP |
| Extended flash | ZAP files | 1Mbyte | ~500K |
See ZAP Memory Sections.
NXP-SCCK ZAP Image File Issues
On the NXP-SCCK platform the ZAP image is stored in flash bank B ('user' flash), and the code executes from flash bank B. . The NXP-SCCK device permits only one ZAP to be loaded on the device at a time. See SDK Memory Size and Availability above.
The ZAP image file does not appear in the ls file listing, as it is located on a separate flash bank.
The ZAP file automatically runs when the device is powered up or rebooted.
To temporarily disable the zap from executing on startup, use the variable:
Use the version command to view the stored ZAP and version. For example:
> version
ZENTRI-TestProj-1.0.0.0, 2016-02-06T00:35:53Z, ZentriOS-WZ-3.0.0.24NXP-SCCK Windows Drivers
When the NXP-SCCK is connected to a Windows computer via USB, the Windows Device Manager should have the following entries:
- Human Interface Devices
- CMSIS-DAP
- LPC-SIO Port
- Ports (COM & LPT)
- LPC-LinkII UCom Port (COMxx)
The entries are shown highlighted in the screen shot below:
If the entries do not appear as shown then the drivers may not be installed correctly.
