Re: [U-Boot] hi, I could not understand the memsize.c, somebody help me?

Hi Aggrwal,

I could not understand common/memsize.c, how it works?

It writes markers at specific memory locations and then reads these back. The algorithm is chosen to be fast but still to be able to detect mirrored address ranges and other memory errors.

Suppose I configure MAX_MEM)SIZE as 1Gig and the actual memory on the board is 512M, is this function supposed to return 512M?

That's the spirit, indeed.
