Re Re: DRAM Size

Thank u very much.

80KB of on chip RAM is available for LH7A404 Processor and it can be used for both program and data. I am planning to use 1MB external Flash memory for program. Do the 80 KB ram is sufficient for the eCOS kernal and peripheral module's DATA RAM

Hi thomas

I think you are new to eCos.
The Non Volatile Memory is specific your Need.
If U talk about the eCos, in One of my Handheld Device With Ecos I have Managed everything in 128 KB Of RAM.
Even you can scale eCos to as low as 32 KB to 64 KB. And If You are Not Sure about the application you Go with 512 KB to 1 MB of Memory then in your final version you can optimise the Size.

Thanks And Regards
