How to find the free space in external SDRAM in u-boot

Santhosh Reddy

Hi,

I am working on firmware upgrade in my project.

I would like to know, how can I find the free space availability in SDRAM from a particular address.

Let's say I need 100MB space to copy an image to RAM location at 0x82000000.

So, how can I find from 0x82000000 location whether 100MB space is available or not?

Please help me in this.

 

Regards,

Santhosh
