Re: [uClinux-dev] Is there any possibility to port uClinux to MPC5566 Microcontroller
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. 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... (the kernel was reduced to the minimum functionality).

Re: [uClinux-dev] Is there any possibility to port uClinux to MPC5566 Microcontroller
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?

Re: [uClinux-dev] Is there any possibility to port uClinux to MPC5566 Microcontroller
it has 128KB internal SRAM only, so there's no chance to run uClinux without adding more ram. I don't know if this chip supports external ram at all. -Erwin Am Monday, den 20.08.2012, 10:37 -0400 schrieb Lennart Sorensen: On Sat, Aug 18, 2012 at 09:51:24AM +0530, Thirumalesha N wrote: This is Thiru, I'm new to uClinux.

I don't know if this chip supports external ram at all. It seems like it can support up to 512MB external ram, but I can't make sense of the datasheet to see whether it works the same as the internal ram as far as running software is concerned, or if it is special data storage memory. -- Len Sorensen ___ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
