Hi developers~:

 

  i am currently working on a project with BF548 Ezkit board.  The project does need an OS on the board so i have read most of related DOCs about how to build and download u-boot and kernel to target. Now there is a question...does the board can running this kernel stand alone...i mean even i unplug power cable it won't loose any data and it will boot correctly image at next time....if it can please help me out: how..?

 

  Also i have seen a awesome demo on the website https://docs.blackfin.uclinux.org/doku.php?id=hw:boards:bf548-ezkit. So i just wondering if some one can help me what kind of cable i need to connect to a USB keyboard and what is the blackfin-linux-dist configuration file if i want to achieve the same results as that video editor's one?

 

  anyway...may everyone have a nic easter.

the BF548-EZKIT has many flash parts on it.  store the kernel on there and have u-boot boot from that.

 

the demo shows the on-board LCD being used.  USB is largely irrelevant to the graphics demos.

the bf548-ezkit has many places to store files.  it's up to you where you store things.  like the manual says, it has 16MiB of parallel flash, 2MiB of SPI flash, a couple of MiB of NAND flash, and quite a few GiBs in the PATA drive.

 

the wiki covers working with each:
