Some RapidIO MegaCore Function Variations Return Incorrect Read Data

Description

When a 4x RapidIO MegaCore function at data rate 5.00 Gbaud with an 8-bit device ID responds to an Avalon-MM read request, it sets the value of io_s_rd_readdata[63:48] incorrectly.

This issue affects all 4x RapidIO variations at data rate 5.00 Gbaud with an 8-bit device ID that implement an Input/Output Avalon-MM slave Logical layer module.

The two most significant bytes in each 8-byte read response datum from an affected RapidIO MegaCore function variation are not reliable.

Resolution

This issue has no known workaround.

This issue is fixed in version 10.1 of the RapidIO MegaCore function.
