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;
