Trying to select a CPU..

Sep 01, 2004 10 Replies

Hello,



in the next few months, I will start a project which involves an embedded linux system. I don't have a complete overview about all suitable devices, especially about the quality of their linux support. So I hope I can get some advice from this group.



Here are the requirements:



o About 10-20K devices per year. o Lifetime = 5 years. o The target is cost-sensitive. o Storage should be nand flash chip. o Booting from NAND flash will reduce total system costs. o Filesystem = ??? YAFFS? o Memory will be SDRAM or DDRAM. 256 Mbit = no Problem. o USB Host support (1 Port). o USB Device support (1 Port). o LCD controller support (less than quarter VGA). o 1 SPI Port. o 1 UART Port. o BGA package, 0.8mm Pitch or more. o Computing Power ca. 100 MIPS. o MMU preferred.



Because of USB Host and Device, Linux 2.6 will be preferred.



The best choice I found so far is the "Cooper" from Netsilicon. Disadvantage: first samples in December, Quality of Linux support unknown.



So, any comments?



best regards Wolfgang Mües



What is this ?

You can check out the via epia/eden boards unless thei are outside your pri= ce range If so you can check out for one of the acrom products or any other company = here:

It's a stripped-down Version of the NS9750. It's not on the Netsilicon Website yet.

The RM9200 is on my list.... can you tell me something about the quality of the linux port? USB drivers available? Which kernel version? Framebuffer device for LCD?

best regards Wolfgang

I don't want a board. I only want to select the right chip for my own board design.

best regards Wolfgang

Thank you for the link.

However, I don't search a board. I want to select the best chip for my own board development.

best regards Wolfgang
