I ended up using this to avoid the timeout (it is a matter of printing
in the lgos the value of the GER_STATUS register and see what is its
final value, then copy it in the code):

      busy = MMIO_IN8(pTrident->IOBase,GER_STATUS) & 0x90;
      if (busy != 0x90) {
        return;
      }

Then, I get somewhat less garbled output but a freeze anyway.
