Tool/software: Linux
Hi Sir
we are using DM385 with IPNC 3.5 (Linux Kernel 2.6.37) for development and would like to use QT.
After checking the wiki's suggestion, we try to insmod vpss.ko and have below message
#cat /proc/cmdline

PC is at kmem_cache_alloc+0x20/0x7c
It might be the vram issue.
Could you offer the suggestion or do we need to modify the memory mapping?
thanks for the reply.
