Hi we need to set the sampling rate for audio transmission through DAC and receiving through ADC, what is the maximum frequency divider that can be used? Is the original frequency 100M samples per second? void ZMODDAC1411::setOutputSampleFrequencyDivider(uint16_t val)

Yes the project is running now. But there is issue when debugging the program, couldn't get over DMA transfer statement as described in a separate post.

Thanks Arthur. The program seems fine when using "Run as" option, but it still gets stuck on the isDMATrnasferComplete() when using "Debug as" option.

Hi, when debugging the ZmodADC Linux program on Eclypse Z7 board, the program stuck on the following statement related to dma.c : // Wait for DMA to Complete transfer while(!isDMATransferComplete()) {} sDMATransferComplete function always returns 0. Any suggestion to overcome this issue?

Hi, I was able to run the baremetal projects on the board, but after building the Linux projects the "Run as" option only shows "Local C/C++ Application". How to modify the project setting to run the program on Eclypse 7 board?

When building the project, the report shows some *.o files can't be found. But the library path was added to the project setting. It seems the linker didn't include the path information.

Hi Arthur, thanks for the information. The project was set up according to the tutorial. The following error was reported: Description Resource Path Location Type 'XPLAT_VERSAL' undeclared (first use in this function) design_1_wrapper_platform_0_1 line 71 C/C++ Problem The ZmodADC Linux demo couldn't run on the Eclypse Z7 board.

Thanks JColvin. It was the port number that needed to be corrected. Somehow the terminal output in Vitis was misaligned after logging in into the board.

Hi, when trying to build the Zmod demo Linux project there are errors: Vitis/2020.2/gnu/aarch32/lin/gcc-arm-linux-gnueabi/x86_64-petalinux-linux/usr/bin/arm-xilinx-linux-gnueabi/arm-xilinx-linux-gnueabi-ld.real: ./src/zmodlib/Zmod/zmod.o: in function `ZMOD::receiveCommands(unsigned int*) [clone .part.0]': zmod.cpp:(.text+0x18): undefined reference to `fnReadReg(unsigned int, unsigned char)' Also other function definition including fnWriteReg, fnAllocBuffer, fnFreeBuffer, fnOneWay, fnIsDMA, fnWriteFlash, fnReadFlash couldn't be found. Any suggestions?

I had connection issue due to not setting the correct COM number. You can try choose a different COM number since there could be multiple USB interfaces on the computer.

Hi, the Windows 10 computer is not able to connect to Eclypse Z7 via serial port. Tried using Putty and COM connection with 115200 baud rate as specified in the guide https://digilent.com/reference/programmable-logic/eclypse-z7/getting-started-guide The MicroSD image was loaded and two top LED lights (1st red, 2nd green) were on. Ethernet cable is connected to the computer directly and IP allocated via DHCP.
