# Limitations
## AMD Xilinx T2 card
- offload of the LDPC encoding implemented for MCS > 2, OAI CPU encoder is used for MCS =< 2
- functionality of the LDPC encoding and decoding offload verified in OTA SISO setup with USRP N310 and Quectel RM500Q, blocking of the card reported for MIMO setup (2 layers)
*Note: AMD Xilinx T1 Telco card is not supported anymore.*
