Errata #1:  

HAR-3274 – Inconsistency concerning the position of general-purpose 
LEDs and the order of related signals on connector X38 

Affected Version:  

Verdin Development Board V1.0B 

Fixed in:  

 

Verdin Development Board V1.1A

 

1.1 

Customer Impact 

This error might create confusion while using this product feature. 

1.2 

Description 

The position of LED21, LED22, LED23, LED24 in the general-purpose LEDs and Switches area is not 
consistent with the order of related signals available on the connector X38. 
This might create confusion when using this product feature. 

1.3 

Workaround 

The table below shows the connections between the X38 connector and the related LEDs. This 
table should be used to avoid confusion when using this product feature.
