Testing
There are a number of additional test functions included in the freely programmable SDK for the
Data Logger Edition. By setting the define UNITTEST the function PerformUnitTest will be
executed after system init. In this function a number of test functions are called. The test functions
will use printf to give user feedback so it is important that printf calls are redirected to a console
window to see the output. It is possible to comment out the test functions that you do not want to
run.
The available test functions are:
Name
Description
EXTFLASH_ReadWriteTest
Test read/write to the complete SPI FLASH
EXTFLASH_SpeedTest
Test read/write performance of the SPI FLASH
EXTRTC_Test
Test the RTC

Upgrading the firmware of the CrossFire IX over Wi-Fi
Note that this is only possible if the firmware on the CrossFire IX supports FOTA updates!
First it is necessary to build a firmware package (an .fwp file). This is done with the CrossFire IX
Tool.
Go to the FOTA tab.
