RP_NOTS Returned by AXI Functions

I am trying to test the AXI mode example for the 4-input Red Pitaya. When compiled the AXI-related functions return RP_NOTS or 24. I am currently using Red Pitaya OS 2.00-18.

Am I doing something wrong, or is the library not finished?

Thank you.

Hello matankeda,

We are currently in the testing stage for AXI mode (with the latest Nightly Builds). If you want to try it out. Please follow the instructions found in the "README.txt" for the Nightly Builds (install the latest Linux OS for Red Pitaya (2.01)), but do not install the ecosystem:
- Nightly builds instructions: ... ly_builds/
- Linux OS:

Next, download the AXI test ecosystem from here:

And extract it according to the instructions in the README.txt (in the Nightly Builds section)

The example should be able to acquire 128 MB per channel with the AXI mode.

Should you need additional help, please let me know.

I was able to download the OS and Ecosystem successfully, but when running the AXI example, the code errors and displays this message:

Reserved memory start 0x108CCD size 0x13A000
rp_AcqAxiSetDecimationFactor failed!
tail: cannot open 'out.txt' for reading: No such file or directory

Could you offer any recommendations for troubleshooting and resolving this issue?

Thank you for the quick reply, it is highly appreciated.

Quick correction,

The AXI functions do work on the 2-input (Z10_125) RP board, but fail to work on the 4-input (Z20_125_4CH) board.

When do you intend to incorporate the AXI features into the 4-input RP?

Thanks again.
