2008-07-17 11:49:06     [U-Boot On Custom Board] Flash Problem

Axel Normand (FRANCE)

Message: 59023   




I'm working on a BF533 custom board based on the BF533-STAMP.


Same RAM


Same Eth controler


Other Flash.


The Flash working, I writing U-boot in by Jtag and booting.


but, U-boot can't see the Flash size. (I have a 4 Mo flash, I will tried tomorow with a 2 Mo).


I dont used a CPLD for switching between flash and Eth but I just used Flash for Uboot and I've mapped the AMS0/1.


I use the configuration of BF533_STAMP to build U-Boot.


a can see on uart this message :

After see the boot processing, I see it's the flash_init() function don't work for me.


If anyone have an idea to help me.

do not modify existing board files.  create your own like the documentation says:



you did not specify your flash settings properly.  you cant blindly copy the settings from a different board when you arent using the same flash.  again, please review the documentation:

Hi Mike,


Thanks for responding me.


I've create my own board files, it run now but dont change the problem whit my flash.


My flash is a CFI flash : but it ID are not describe in include/flash.c


did I need to add it ? or did I need to do more ?


Amic 4Mo flash but only 2Mo are map. constructor id : 0037 and divice : 22f9 like detect say.

I dont know why my flash are not detected ! Did it run better with a more classic flash distributor like AMD or STM ?

sorry, but i dont speak french, so i have no idea what that output says


whether urjtag knows the exact flash id doesnt really matter ... u-boot operates on a completely different database

for the output, I've just posted it for you see where I find the flash id.


u-boot oprerates on a completely different database ?! really


I do the same detectflash whit urjtag on a bf533_stamp :


manufacturer id : 0x0020 for STM


Module id : 0x22CB


and i find this number in include/flash.h !




did I need to do add a support of my flash memory ?


if yes, need I to do that on my board directory or other flash.c ?




I'm realy dont know where my problem come from and how to resolved it.




PS : I will receive a new ship who are list on flash.h , maybe it will solved partialy my problem.

Message: 59088   


why would you think urjtag and u-boot share code ?  they're completely different projects which means they have completely different code bases.


you said you simply copied the bf533-stamp settings.  that means you did not read the documentation and you did not update the flash settings in the board configuration header to actually reflect your flash.  you cannot expect the flash to work if you dont use the right settings.


the wiki page i posted earlier explains the settings you need to set correctly ... please actually read it:

I got it.


I see my flash, I just have an error : I set harware protect at 1 instead of 0.


now flash running correctly, thanks a lot for your help.
