When reading https://github.com/apache/nuttx-apps/pull/1793, I found a previous problem https://github.com/apache/nuttx-apps/pull/1454#discussion_r1045718067 now still exists on current master (inf in iperf bandwidth).
By step-by-step debugging, I found a value of 1000000.0 stored in register d8 is overwritten as 0 after context switch, then fdiv results in inf because of divided by 0. Finally I found that ARCH_FPU is not enabled while compiler is using FPU, and may lose values in floating-point registers.
