Is it possible to boot from compact flash?

Hi bkucera,

Yes, provided you can download the correct binary images. U-boot can read/erase/write the

epcs device -- so if you tftp the binary image into main memory for example, u-boot can

write it to the epcs device. Creating the appropriate binary image(s) is usually where people

have trouble -- copying to the epcs device is the easy part ;-)

> Also is there any issue with multiprocessor designs?

I've never tried u-boot in a multiprocessor environment. But I don't think there would be any problems.

Just run u-boot on one of the cores (with access to the required peripherals: timer/uart).

> Is the idea of copying SOF/program data from the CF card to the onboard flash valid?

I've been assuming that you're referring to a serial configuration device -- regardless, u-boot can

parallel flash as well as the epcs.
