Hi all,
I have done a reset test IMX6 Solo with Uboot 2013.04 and kernel 3.10.17, the system reset every 15 seconds after startup. After a day, the system hangs at ipuv3_fb_shutdown() function in Uboot. PLease help some advices for this issue! Thanks.
void ipuv3_fb_shutdown(void)
{
printf("\n *********** IN FUNCTION ipuv3_fb_shutdown\n");
int i;
struct ipu_stat *stat = (struct ipu_stat *)IPU_STAT;
printf("\n *********** %s: ipuv3_fb_shutdown step 1\n", __FUNCTION__);
for (i = 0; i < ARRAY_SIZE(mxcfb_info); i++) {
struct fb_info *fbi = mxcfb_info[i];
if (fbi) {
struct mxcfb_info *mxc_fbi = fbi->par;
ipu_disable_channel(mxc_fbi->ipu_ch);
ipu_uninit_channel(mxc_fbi->ipu_ch);
}
}
printf("\n *********** %s: ipuv3_fb_shutdown step 2 \n", __FUNCTION__);
for (i = 0; i < ARRAY_SIZE(stat->int_stat); i++) {
__raw_writel(__raw_readl(&stat->int_stat[i]),
&stat->int_stat[i]);
}
printf("\n *********** %s: ipuv3_fb_shutdown step 3 --> DONE\n", __FUNCTION__);
}
Best Regards
