AM1808 hardware design for SPI flash

Other Parts Discussed in Thread: AM1808

Hi,

I have some queries on AM1808. We are designing our own customized product. Here we are using AM1808 with SPI flash only (No NAND & NOR). Our SPI flash size is 8 MB.

In Final production where will keep our JFFS2 file systems. 

  • Whether will keep Jffs2 filesystems in SPI flash?
  • Or only we can keep ramdisk as a root file system in to the SPI flash??
  • Will it fit both the images (Kernel uImage & FileSystem (jffs2/ramdisk)) in a single SPI flash itself? 

In our design we are using SD-Card for data Logging. Please recommend me any suggestions to take care our hardware design for keeping the kernel image (uImage) and file system on SPI flash.

Thanks

Francis
