Dear all,
I use Android 4.2.2 on iMX.6
I want to reset IPU3 CSI0 interface manually when CPU get an interrupt,
and I run theses functions as below, but they don't work.
----------------------------------------------------------------------------------------------------------
ipu_disable_csi(&ipu_bk_0, 0);
ipu_disable_channel(&ipu_bk_0, channel_bk_0, 1);
ipu_uninit_channel( &ipu_bk, // The function would initialize some parameters.
channel_bk);
ipu_csi_set_window_size(cam->ipu, cam->crop_current.width,
cam->crop_current.height, cam->csi);
ipu_csi_set_window_pos(cam->ipu, cam->crop_current.left,
cam->crop_current.top,
cam->csi);
ipu_csi_init_interface(cam->ipu, cam->crop_bounds.width,
cam->crop_bounds.height,
pixelformat_bk1, csi_param_bk1);
ipu_init_channel( &ipu_bk_0,
channel_bk_0,
params_bk_0_test);
ipu_init_channel_buffer( &ipu_bk_0,
channel_bk_0,
type_bk,
pixel_fmt_bk,
width_bk,
height_bk,
stride_bk,
rot_mode_bk,
phyaddr_0_bk,
phyaddr_1_bk,
phyaddr_2_bk,
u_bk,
v_bk);
ipu_enable_channel(&ipu_bk_0, channel_bk_0);
ipu_enable_csi(&ipu_bk_0, 0);//csi=0
----------------------------------------------------------------------------------------------------------
At first, there are video on display, but when I reset IPU3 CSI0 interface,
there are no video on display and I got the message :
" imx-ipuv3 imx-ipuv3.0: Warning: channel already initialized 15 "
Could anyone tell me what happened?
Thanks for your reply,
zohan
