How long have you waited? Depending on a firmware installed, Bus Pirate may be a little slow: check the Bus Pirate Community Firmware project for the firmware updates. Also, try running this with a higher verbosity, i.e. -VV or -VVV or even more V - that could give you some hints. Also please make sure that your connectivity is good enough

Hi flashrom team,
i try to read the mx25l3255e (https://media.digikey.com/pdf/Data%20Sheets/Macronix/MX25L3255E.pdf) chip. But it don't work. I have tried to patch flashrom but output say:

But then nothing happens. Can you help? That would be great!
