Run from flash and use flash device driver?

Hi Andrew,

This makes sense ... If you do something as simple as (trying) to read the

manufacturer and device IDs, you won't be fetching instructions any

longer -- you'll be trying to execute the IDs ;-)

Fair enough ... but that's not the problem. If you're executing code that's

being fetched from the device that you're programming, a (typical) device

will not be driving array data onto the data bus. It will insted be driving

the write status (e.g. toggle bits, etc.). So you won't be fetching valid

instructions.
