Message: 51351 hai all,
i'm trying the PPI driver by zhi chen lee as my driver and bfin_capture.c as my application to check for the data in the SDRAM in BF561 Ekit lite. I made some modifications in the application jus to check, in the driver the code hangs up at the following function which is in bold.
source copied and pasted.
if (pdev->nonblock)
return -EAGAIN;
else {
pr_debug("PPI wait_event_interruptible\n");
printk("\n in_wait\n");
ierr = wait_event_interruptible(*(pdev->rx_avail), pdev->done);
printk("\n aftr_wait\n");
if (ierr) {
/* waiting is broken by a signal */
pr_debug("PPI wait_event_interruptible ierr\n");
return ierr;
}
}
i have seen the topic regarding this already in the forums
i made the necessary switch settings and RESET flag and OE FLAG for ADV 7183.
