Hi, Well, it's actually pretty clear on the reference manual:
[...] External Bus Interface (EBI) The external bus interface (EBI) controls data transfer across the crossbar switch to/from memories or peripherals in the external address space. The EBI is available on the 416 BGA package only. The EBI also enables an external master to access internal address space. The EBI includes a memory controller that generates interface signals to support a variety of external memories. The memory controller supports single data rate (SDR) burst mode flash, external SRAM, and asynchronous memories. In addition, the EBI supports up to four regions (via chip selects), along with programmed region-specific attributes. [...] If you're using the 416 BGA package you're good to go... (you can also add more FLASH) Regards On Tue, Aug 28, 2012 at 2:29 PM, Luis Alves <lja...@gmail.com> wrote: > Hi > > On Tue, Aug 28, 2012 at 12:16 PM, Thirumalesha N <thiru.li...@gmail.com> > wrote: >> >> >>> How much ram does one of those systems actually have? >>> >>> As far as I can tell the CPU is a powerpcspe, which already has support >>> in plain linux, but it very well might have way too little ram to actually >>> run linux. >>> >> >> As per Freescale view, There is no support for Linux porting and also they >> mentioned it is not support uClinux. it will support upto 128KB SRAM only. > > If the cpu supports external RAM then I guess it can run uClinux. > The 128Kb on-chip SRAM is usually used as scratchpad (faster memory). > >> >> To run uClinux how much minimum SRAM Required? > > I've been able to run uClinux with kernel 2.0.x in a system with 512Kb > RAM, but you'll be limited in what you can do...
