DM368运行encodec时,会出错:
rsz_set_output_address 0
rsz_set_output_address 1
Unable to handle kernel NULL pointer dereference at virtual address 00000003
pgd = c26d8000
[00000003] *pgd=822b9031
, *pte=00000000, *ppte=00000000
我们自己做的dm368板子,encode运行几分钟后会出错
谁遇到过?

你好我也在搞dm368,我想问你下,那个uboot配置参数是用什么,比如:
setenv bootargs mem=60M console=ttyS0,115200n8 noinitrd rw ip=192.168.1.80:255.255.255.0:192.168.1.1 root=/dev/nfs nfsroot=192.168.1.100:/home/davinci/dm368/dvsdk_dm368_4_02_00_06/filesystem/dm368rootfs video=davincifb:osd0=720x576x16,4050K dm365_imp.oper_mode=0 davinci_capture.device_type=4
你用的是什么?谢谢

我后来用UBL_DM36x_NAND.bin启动板子,就是把ARM、DSP等频率降下来,ARM跑297Mhz,encode就能稳定运行一天多。
估计硬件布板可能有问题,我还要进一步测试。
