2009-08-16 22:28:28     SPI File System in Blackfin uClinux

Hi,

 

Currently we want to put two SPI flash in our BF537 board.  My initial plan is : One SPI flash is for boot / kernel / file system , and another SPI flash is totally file system. Can blackfin uclinux support this?

 

Or there have any other method to make TWO SPI FLASH running at blackfin uclinux at the same time?

 

 

 

Thank you very much!

there is no software limitation with flash partitions or filesystems and number of devices.  you could run as many spi flash devices with as many partitions as the hardware can support.

Thanks! Mike.

 

But my question is  how to make all the SPI FLASHs into JFFS2 file system and also mount them to a certain directory under the root directory? Do there have any examples or instructions?

What Mike is saying - is it doesn't matter what the name is - /dev/mtd1 or mtd2 can be on different physcial devices - or the same - it is controlled by the board data. Set up your board data properly - the rest should fall out.
