[U-Boot-Users] Intel 28F256J3C

[U-Boot-Users] Intel 28F256J3C

[xuxian]

Hi all,

I try to make u-boot work on my board which is similar with OMAP5912OSK. But
the flash we using is 28F256J3C. I have already added 28F256J3C's
manufacture code and device id in the proper position of u-boot. But there
are several questions I can't figure out. 
1) How many sectors does 28F256J3C have? 256 or 259? How to divide 259
sectors in OSK which have two 16M flash. 
2) What's the meaning of "Internal FLASH identification codes" in flash.h
file. It defines like this: 
#define FLASH_28F320J3A 0x00C0		/* INTEL 28F320J3A ( 32M = 128K x
32)*/
#define FLASH_28F640J3A 0x00C2		/* INTEL 28F640J3A ( 64M = 128K x
64)*/
#define FLASH_28F128J3A 0x00C4		/* INTEL 28F128J3A (128M = 128K x
128)*/
But I can't find this kind of information on 28F256J3C's datasheet. And what
the code should be in 28F256J3C?
3) Should I modify the read manufacture and device id command? I have some
trouble with the following codes:
/* Write auto select command: read Manufacturer ID */
	addr[0x5555] = (FPW) 0x00AA00AA;
	addr[0x2AAA] = (FPW) 0x00550055;
	addr[0x5555] = (FPW) 0x00900090;
Sorry for my English. Any help will be appreciated. Thank in advance.

Best Regard,
xuxian

Any reason for not using the CFI driver?

How about reading the chip manual?

How about reading the comments in this file:

/*-----------------------------------------------------------------------

 *
 * Be careful when adding new type! Odd numbers are "bottom boot sector" types!
 */

Do you really expect to find U-Boot internal information in the  chip
manual? I'm afraid we are not *that* prominent yet.

Probably this is not the command  sequence  expected  by  your  flash
chips. Please read the chip manual.

Please take Wolfgangs advice and use the common CFI flash driver. The current 
U-Boot OMAP5912OSK port also uses this driver. It should work without any 
changes with your flash type.

[U-Boot-Users] Which configuration?

Hi,

I would like to update the U-Boot of my embedded jukebox. It has a PPC 405 CPU without FPU. I was reading the documentation on the denx site and the README in the source distribution, but I did not really find out which configuration would best fit me.
Can you please point me to some good documentation? What are TQM8xxl boards and how do I find out, whether or not I have one?

Thanks,
Norman

Which one? 405GR, 405GPr, 405CR, 405EP? Or something else? It's not easy to 
recommened a board that fits your need the best without any knowledge about 
it.

Also good to know would be what kind of FLASH  you use (type and width), and 
how the SDRAM is connected to your CPU (DIMM module or onboard).

With such informations you can look through the different 405 board config 
files and chose the one that fits the best to your custom design.

TQM8xxl are MPC8xx based CPU modules from TQ Components.

No. Walnut is the 405GP eval board. Seems that board port was kind of a quick 
hack, when such inaccurate information is still in the object.

As Wolfgang already told you, please contact the board manufacturer to get the 
U-Boot source. That's definately the best start to get it ported to the 
current U-Boot version.

Stefan

You mention "update", i. e. there is  already  a  version  of  U-Boot
installed.

Why dopn;t you just check with the source tree you received for  your
device?  You  did  receive  one,  or  at  least  a link where you can
download it, right?

What's the name of your device?

> Can you please point me to some good documentation? What are TQM8xxl

TQM8xxL modues are MPC8xx based systems; they have nothing to do with
your 405 based system.

I do not think they want me to have the source.

They may not want it, but they HAVE  TO.  The  software  is  licensed
under  GPL  so  they have no choice. If you didn't receive the source
code, was then your product accompanied "with a written offer,  valid
for at least three years, to give your (and actually any third party)
a complete machine-readable copy of the corresponding source code ?

Please let me know if this was not  the  case.  I  take  such  things
seriously.

They have introduced a harddisk lock in their newest revision, that's why I suppose they will not react in any way to my inquiries. As an individual I am not in a position to negotiate either.
The device itself is not accompanied by any written offer or any other advanced documentation or support.

The manufacurer's web page is at:

http://www.hermstedt.de

the product is the hifidelio. The web page is currently down, though.


What I thought to have understood from your and Mr. Roese's mail is that with the information at hand nobody will be able to point me to a valid configuration?


Sincerely,

Norman

They have to. It's law.

You don't have to negotiate. Please just ask. If they don't give  you
the full sources, I will take care of it.

OK. So they are already violating the GPL.

Indeed.  Not  a  good  sign,  problably.  Do  you  have  any  written
information  (snail  mail  address, phone numbers etc.?) [Please send
this to wd at denx.de - no need to bother the list.]

Right. You would need  a  detailed  documentation  of  the  hardware,
ideally  including  the  schematics,  but  I guess you don;t get this
easier than the U-Boot sources.

Since U-Boot license is GPL, they are required to deliver the source 
code free of charge upon request (except a reasonable amount for 
preparation of media and shipping).

While not disputing your right to update, what is your incentive to 
update U-Boot code since it is unlikely to add any new features that you 
might need in your Jukebox? If it is working fine, there is no real good 
reason, I would recommend not to update boot loader.

In the meantime I have sent 2 e-mails. They have reacted on the 2nd and 
promised to give me the source. I am curious on what I will get...

I always need to have the latest version installed, don't you? ;-)
As I have written in another mail in the same thread, there is a Hardware lock 
in the "original" U-Boot, probably with a similar philosophy behind like the 
image lock Rohit Sharma proposed these days on this list and I don't see why 
my jukebox should only work with a TravelStar 80GB hard disk and not with any 
other HD, especially my newly bought 160GB...
I am sure I will find the explanation right beside the "if" being responsible 
for the lock. Good software writers always explain with comments what they 
are doing!

They have sent me a source tarball. I make it available to the readers of the 
list at:
http://www.normiboy.ch/tute/u-boot-0.4.0wmc.tgz
inside should be either a 0.4.7 or a 0.4.8 u-boot, I did not check that yet.

An integration into the official source might be appropriate, maybe I will 
find time to do something,

Norman
