The following code may be substituted for the broken code in fwdev.c, line 325 (in the routine fw_read) to allow downloading of digital camera images. #if 1 /* XXX fixed ? */ /* per packet mode or FWACT_CH bind?*/ s = splfw(); ir->queued --; STAILQ_REMOVE_HEAD(&ir->q, link); splx(s); fp = &xfer->recv.hdr; if (sc->fc->irx_post != NULL) sc->fc->irx_post(sc->fc, fp->mode.ld); err = uiomove((caddr_t)fp, sizeof(struct fw_isohdr), uio); err = uiomove((caddr_t)xfer->recv.payload, xfer->recv.pay_len, uio); #endif Changing the receive channel, however, results in the message: fwohci0: IR DMA no free chunk Is changing channels not supported? After the above message, the code returns 0. So maybe this message is not really an error. Buzz Slye NASA/Ames
