DESCRIPTION:The use of open-source stacks with the Open~RAN (Radio Access N
 etwork) architecture has been predominantly restricted to x86 and ARM arch
 itectures. This work presents the first successful porting of the srsRAN P
 roject to RISC-V\, targeting the low-cost Banana Pi BPI-F3 (SpacemiT K1 So
 C)  board. We describe the cross-compilation toolchain\, the removal of AV
 X/NEON dependencies in favour of a scalar C fallback\, and a preliminary p
 erformance evaluation across two 5G NR FDD scenarios. Profiling with Linux
  perf identifies key data-parallel physical layer (PHY) bottlenecks\, esta
 blishing primary targets for RVV 1.0 vectorisation. Results show that RISC
 -V offers promising real-time MIMO performance for a single user\, even wi
 th a scalar fallback\, suggesting that vectorisation will elevate it to hi
 ghly competitive levels.
