Hello Everyone.
We use DVRRDK_03.50.00.05 SDK to develop product.
APP is working <capture -> encoder->write file>
if we config DVRRDK_03.50.00.05 SDK to 2G Memory。Platform is TI8168EVM Board。
after do ./init.sh ./load.sh everything look better.
Then ./bin/app.out The CPU is hung up when run to System_linkCreate(encId, &EncPrm, sizeof(EncLink_CreateParams));//hung up in cortex-a8
hung up when run to memset(pBaseAddr, 0x80, (size * numFrames));;//hung up in m3video (file at ./mcfw/src_bios6/src/utils_mem.c Line 738 to clean mem)
I have printf that pBaseAddr = 0x80000080. (Can not Access that Memory？？)

Then I had config DVRRDK_03.50.00.05 to use 1G Memory.
rebuild this SDK and APP
./init.sh ./load.sh ./bin/app.out
Everything is OK. This H264 file is write.
Then printf pBaseAddr = 0x90000080

So somebody Can help me ? what is error?
How can I fix this Problem？
I guess the Memory at 0x80000080 can Access.Because of when we config the SDK to use 1G Memory,The ARM cortex-a8 is use that address.
thank you ！
