I'm a rookie,and i trying to make a single wave TX,as the pic I attached.

i dont know why the loop of TX data is success only when first loop but second loop start being wrong?and I got error code -1074118645.

can anyone please guide through this problem?TXRX

It occurs when the first code execution is forcibly terminated rather than a normal termination. I guess it was because the FPGA settings were twisted after that. To solve this problem, press the stop button on the front panel, not on a forced shutdown in the execution menu bar.

Thank you for answer my question,

but what I actually want to ask is how to make this being none-stopped loop,not ended in one loop?

is data wrong or the setting?

I'm sorry. I misunderstood your question. The error you see is the underflow error. What is the size of the input array in the Tx loop? It seems to be solved by increasing the size of this array. (y in the cluster)
