Our testing of AD-FMCOMMS1-EBZ REV B is not successful, two errors:
1.After the hardware is generated on Vivado2014.2, the projects don't run as the demo. The SDK says"target is not responding(timed out) " when debug the projects.
(reference link::ADI Reference Designs HDL User Guide [Analog Devices Wiki])
2.Sometimes the program can run, but stops at
/* Wait until the current transfer is completed. */
reg_val = Xil_In32(baddr + AXI_DMAC_REG_IRQ_PENDING);
while(reg_val != (AXI_DMAC_IRQ_SOT | AXI_DMAC_IRQ_EOT));
(reference link :: AD-FMCOMMS1-EBZ Quick Start Guide on Xilinx FPGA Boards Without OS [Analog Devices Wiki])
(software version:: no-OS-2014_R2)
this is the UART prompt when the program can run:

I am a totally newer at this and my englishi is not good, so be patient with me.
Any help will be appreciated!!!
thanks very much!!!!
I've just done a test using a KC705 revision 1.2 (the changes from rev. 1.1 to 1.2 are minor: AR# 59751 - Kintex-7 FPGA KC705 Evaluation Kit - Changes from rev 1.1 to rev 1.2) and everything works fine.
Your board gets stuck during the DMA configuration, so there could be some problems with the memory. Do you have another KC705 board to also try with it?
