Follow-ups

--- Michael Hennerich 2008-04-23 10:41:21

This is not a bug.

It's a matter of hardware - the EZkit is designed that way.

In order to test NAND on the BF527-EZkit - you have to disable the bfin_mac

driver. And invert all SW1 (ETH Enable Switches).

See here (disable Ethernet):

docs.blackfin.uclinux.org/doku.php?id=hw:boards:bf527-ezkit

-Michael

--- Robin Getz 2008-04-23 16:42:08

Michael:

The bug is not that it conflicts - it is that it crashes the kernel, rather

that just not loading the driver.

We should be able to compile both as module. install one, install the 2nd

(which should fail - gracefully), and then continue on.

The one that gets their first should "win" - but we should never

crash the kernel.

-robin

--- Michael Hennerich 2008-04-24 04:48:02

Your absolutely right.

I didn't notice the crash, because I didn't scroll down the tiny Details window

up to the bottom. I just saw the fail message.

Fixed now.

The peripheral request was happening after peripheral initialization, which is

totally wrong.

-Michael

--- Michael Hennerich 2008-04-24 04:49:10

Change resolution to fixed.

--- Mingquan Pan 2008-04-24 23:31:01

Yes,fixed.Now the fist module that is inserted could win the resource and

work.Kernel does not crash.
