- CR 304087: M_SYS_FM_RDY_N may not correctly signal the end of a superblock
To work around this issue, the user can count the number of qwords received using the signals M_SYS_SRC_RDY_N and M_SYS_DST_RDY_N. Based on the type of core traffic the core is set to receive (e.g., PLI), the user can determine when a superblock is ending and can then switch channels.
-CR 475981: Hardware timeout counter is not properly disabled. The core might stop functioning in the device after two hours.
