“Status: No data in stream” in ROHM EVK GUI SW Status Bar
This status means that the ROHM EVK GUI is not receiving any data from the device stream.
Figure 19. Status Bar, No data
NOTE:
This error example issue is limited for RKX-EVK-001 connections.
If the connection status as indicated in the status bar says “No data in stream”, the ROHM EVK GUI SW is not receiving any device data. To
troubleshoot the issue, please check the following:
This example case is valid for RKX-EVK-001 with an EVB.
1.
The
orange
LED2 should be ON (Figure 18). If the
orange
LED2 is OFF, check the following:
•
Check if the SW4 is in the ON position (i.e., moved up as seen from above) (Figure 18).
•
If the SW4 is ON, check that the 7-position rotary switch SW2 (Figure 4 and Table 1) is not stuck in the intermediate
position. The switch can be turned with a small flat screwdriver (Table 1).
NOTE:
When using the ROHM EVK GUI SW and the SW4 in the incorrect position, the Help menu item (1.3.9.4 About Host Adapter Board in
ROHM EVK SW User’s Guide) would still work properly because the information about the host adapter firmware is read out from the CY8CKIT-
059 Prototyping Kit, not the sensor.
2.
The
orange
LED2 is ON:
•
Check if the Stream selected corresponds to the sensor being tested (1.3.6 Stream
– Menu in ROHM EVK SW User’s Guide).
NOTE:
The ROHM EVK GUI SW does not check the value of the WHO-AM-I register. Thus, while the stream for KX132-1211 would work for
KX134-1211 and vice versa (although SI values in Raw Data setting will be incorrect), neither of those streams would work if KXTJ3 sensor is
connected and vice-versa.
•
Evaluation sensor board is securely connected to the ROHM EVK EVB either directly or with the ribbon cable (Figure 11
.
•
Press the CY8CKIT-059 Reset Button (Figure 18). Wait a few seconds. If the
status changes to “Connected”, press the “Streaming”
button.
•
Unplug the CY8CKIT-059 Prototyping Kit from the PC and plug it back in. Wait a few seconds. If the
status changes to “Connected”,
press the
“Streaming” button.
•
Close the ROHM EVK GUI SW. Unplug the CY8CKIT-059 Prototyping Kit from the PC. Plug in the CY8CKIT-059 Prototyping Kit
and restart the ROHM EVK GUI SW.
