Hi Massimiliano,
If you run your command with -l 4 option you should see the output like the
following. I think that can work for your use case to identify MOSI and MISO
lines.
sigrok-cli -i mx25l1605d_probe.sr -P
spi:wordsize=8:cs=CS\#:clk=SCLK:mosi=MOSI:miso=MISO -A
spi=miso-transfer:mosi-transfer -l 4
[. . .]
5991362-6009713 spi-1: miso-transfer: "FF C2 20 15"
5991362-6009713 spi-1: mosi-transfer: "9F FF FF FF"
6015830-6057950 spi-1: miso-transfer: "FF C2 20 15"
6015830-6057950 spi-1: mosi-transfer: "9F FF FF FF"
6061683-6109695 spi-1: miso-transfer: "FF C2 20 15"
6061683-6109695 spi-1: mosi-transfer: "9F FF FF FF"
6115310-6159691 spi-1: miso-transfer: "FF C2 20 15"
6115310-6159691 spi-1: mosi-transfer: "9F FF FF FF"
6165812-6209683 spi-1: miso-transfer: "FF C2 20 15"
6165812-6209683 spi-1: mosi-transfer: "9F FF FF FF"
6215803-6259676 spi-1: miso-transfer: "FF C2 20 15"
6215803-6259676 spi-1: mosi-transfer: "9F FF FF FF"
