 **Notes:**
+- `UART_QSPI_PROGRAM=1` adds a 3-second boot pause every time. Set to `0` once the flash contents are stable.
 - `ELF=0` is required: the test-app linker script (`test-app/RISCV64-mpfs250.ld`) places `.init`
   (containing `_reset()`) first so the raw binary entry point is at offset 0. The full ELF with
   debug symbols exceeds L2-LIM capacity.
