Author Topic: Why is my camera configured with 64M RAM, but has 128M chip?  (Read 4496 times)

I have a Hi3516C based board, and this is the RAM chip on board:
http://www.samsung.com/semiconductor/global/file/2011/product/2011/6/24/013928ds_k4b1g1646g_x16only_rev111.pdf

It looks to me like a 128MB chip.
However, my vendor default uboot arguments are:
mem=64M console=ttyAMA0,115200 root=/dev/nfs nfsroot=10.0.1.109:/nfsroot,nolock rw rootdelay=0 init=/init


So, it seems that the unit is configured for 64M of RAM, even though it has 128M on board...

I have tried changing the value from 64M to a higher value - and it just causes the camera software (the RTSP server) to fail to start.
It boots fine - in fact, I can set the value to 256M or 512M, and it still boots, but the IPCAM executable just doesnt work properly....

Does anyone know anything about this?
Am I correct, but I'm not changing everything I need to, to bump it's accessible memory to 128?

I'd really like this camera to have access to all the RAM is it's not currently...

Thanks
