dm355: previewer freeze target

Klaus Schwarzkopf

Hi,

my setup:

mt9v126 -> CCDC -> IPIPE (raw bayer-> YUV 422) -> SDRAM -> V4L2 -> LCD

Leopardboard DM355, Linux davinci (r37), examples davinci (r37)

I run the imp-prev-rsz/dm355/capture_prev_rsz_onthe_fly_bayer.c demo, but the function (line 799)

if (-1 == ioctl(fdCapture, VIDIOC_STREAMON, &type)) {

does not return. If i comment out this line

//preview_fd = init_previewer(user_mode); // line 900, disable previewer

the target don't freeze.

Can you help me?

Regards,

Klaus

Klaus Schwarzkopf,

since you are using IPIPE in continuous mode, you need to set bootargs to indicate the same. Can you check that?

Hello Nagabhushana,

my bootargs are:

setenv bootargs mem=96M console=ttyS0,115200n8 root=/dev/nfs rw nfsroot=192.168.0.20:/home/klaus/fs

ip=192.168.0.110:192.168.0.20:192.168.0.1:255.255.255.0:leopard:eth0:off ethaddr=00:09:45:53:d1:b3

davinci_enc_mngr.ch0_output=LCD vpfe_capture.interface=1 video=davincifb:osd1=0x0x8 vpfe_capture.debug=1 dm355_imp.oper_mode=0

If dm355_imp.oper_mode=0 isn't set, the demo don't start.

Regards,

Klaus
