# AWS Shell Release Notes # F1 XDMA Shell - F1.X.1.4(v04261818) * Fixed AXI-L Interface Ordering. Read requests on the AXI-L interfaces (BAR1, OCL, SDA) will not pass previous write requests. * Increased XDMA PCIS interface timeout to 5 seconds * Clock group A supports synchronous clocks within the group (default is clocks are synchronous) * Added backpressure signalling to XDMA (note added signals to cl_ports.vh - **cl_sh_dma_wr_full/cl_sh_dma_rd_full** _Note: If not required, these signals should be tied to '0'_) * Shell update capability (Shell can be updated without requiring CL re-build) * Added AxBURST to DDR_C interface (note added signals to cl_ports.vh - **cl_sh_ddr_awburst[1:0]/cl_sh_ddr_arburst[1:0]** _Note: Only INCR burst mode is supported so these signals must be tied to 2'b01_)
