Using RAM as temporary storage
Added by Alexander Block almost 12 years ago
Posting on behalf of a customer:
Customer wants to store data to the SD card but believes they will be bursting more than the write speeds that we have tested for the SD card interface (http://support.criticallink.com/redmine/projects/arm9-platforms/wiki/MMCSD_Card_Throughput). They had the following question in regards to a possible solution:
Do I have access to the on board 128MB DDR memory? Can I use it for my temporary storage needs? If so, how much storage space will I have?
This is important since if this memory is not accessible I must add an additional memory chip on my base board.
Thank you,
Alex

The 128 MB of Memory is total system memory. Some of it is used for the kernel and application space, but typically not all of it.
We have had some kernel and application foot prints as small as 12 MB, which would leave a larger chunk available for some sort of RAM drive.
