Follow-ups

Grace:

 

I think there are two different bugs here. Can you post them separately?

 

The first:

 

>

>peripheral_request: Peripheral 32 function 0 is already reserved by

bfin_mac

 

but it looks like we are not handling the error condition properly...

 

>bf5xx-nand: Requesting Peripherals failed

>bf5xx-nand: probe of bf5xx-nand.0 failed with error -14

>Data access misaligned address violation

 

failing the probe should not cause the kernel to crash.

 

The 2nd:

>BF5xx on-chip NAND FLash Controller Driver, Version 1.2 (c) 2007 Analog

Devices, Inc.

>bf5xx-nand bf5xx-nand.0: page_size=256, data_width=8, wr_dly=3, rd_dly=3

>NAND device: Manufacturer ID: 0x20, Chip ID: 0xdc (ST Micro NAND 512MiB

3,3V 8-bit)

>No oob scheme defined for oobsize 256

>BUG: failure at drivers/mtd/nand/nand_base.c:2438/nand_scan_tail()!

>Kernel panic - not syncing: BUG!

 

is just large page flash issue (I think)?

Separated.The first one is going to bug 4053.This one tracking the secong issue.

 

--- Mingquan Pan                                             2008-04-24 01:59:16

Yeah,after invert SW1 to off off on off, the kernel with nand driver can boot up

normally.

But then another problem is it looks this design makes it impossible to run the

case automatically and everytime I need to download the image I enable the

ethernet card,and when booting this kernel,I have to invert back...

 

--- Mike Frysinger                                           2008-04-24 02:32:49

well, there's literally nothing we can do about it.  it's a hardware issue, not

a software one.  i'm not even sure it can be solved automatically in hardware

(presumably if it were possible, i'd be fixed already).  the BF52x processors

themselves mux the MAC and the NAND controller so they cannot be used

simultaneously.

 

so yes, testing NAND on the BF527-EZKIT will have to be manually done.  or you

load it over the serial port ;).

 

about the only thing here for Michael to do is make sure there is proper error

checking when resource allocation fails.

>Yeah,after invert SW1 to off off on off, the kernel with nand driver can

normally.

 

Please close.

--- Robin Getz                                               2008-04-24 09:00:42

Grace:

 

Mike is correct - you can load the compressed uImage (please start using this

in all your tests?) over serial port.

 

Closing this bug.
