[U-Boot-Users] AT91SAM9260-EK: Trying to load U-Boot env from NAND

[U-Boot-Users] AT91SAM9260-EK: Trying to load U-Boot env from NAND

[Destrukto]

Hello, this is my first post in this Forum and my English is not very good so
I give my best to describe my problem.

I have a AT91SAM9260 eval kit board and until now there were not very much
problem. But what stops me now is a really tough problem. I use the
Bootstraploader for NAND boot which is compiled by Atmel in the Demo. I've
compiled the U-Boot by my self and its starts without problem, but what get
on my nerves is that I can't write the U-Boot env over .tcl file. To explain
that, I load everything, just like it is done in the demo, with this batch-
and .tcl-file. So, I've checked the checksum for the env's but everytime I
uploaded it and trying to boot I get this:

U-Boot 1.1.5 (Nov  2 2006 - 10:20:33)

DRAM:  64 MB
NAND:  NAND device: Manufacturer ID: 0xec, Chip ID: 0xda (<NULL> NAND 256MiB
3,3V 8-bit)
256 MiB
DataFlash:AT45DB642
Nb pages:   8192
Page Size:   1056
Size= 8650752 bytes
Logical address: 0xD0000000
Area 0: D0000000 to D0003FFF (RO)
Area 1: D0004000 to D0007FFF
Area 2: D0008000 to D0037FFF (RO)
Area 3: D0038000 to D083FFFF
*** Warning - bad CRC or NAND, using default environment

End of Autonegociation
U-Boot>
U-Boot>
U-Boot> printenv
bootdelay=3
baudrate=115200
stdin=serial
stdout=serial
stderr=serial

Environment size: 69/131068 bytes
U-Boot>

I checked the env (nand read to copy them in the RAM and md to hae a look at
them) and they're still correct. Well, I could write the env every by hand
that would work but if you have to do this 20 times a day and you have
really much to write this wouldn't be very funny. 

So I hope I haven't forget anything, but if there is any question I will try
to answer.

Greets, Destrukto

[Dharmosoth Seetharam]

Hi,

If I remember correctly, i got the same issue on
AT91SAM9263ek.

you please debug the Dataflash_Select() ... 
there u many need to go into the if condition and
do valid=1;


so, please check it once and modify the condition...

u may get the solution ..

Thanks,
Seetharam

Yes! I get it work, the problem was, that it had a problem to accept the
crc32-Checksum. So I just erased the sequence where this happens. Here the

You mean you completely castrated all logic that would verify if the
environment is OK? Arrggghhhh...

> Maybe it isn't the best solution but it works ;)

You THINK it works, but actually it's completely broken.

Don't do that!!!

Well, until now I haven't got any problem with this solution. So until I
can't find any better solution I will use the system as long as it works.

You probably don't have a problem but your customers will get them.
I wish you some luck when your product goes to mass production if you
neither have found out why your environment storage has problems nor
if you don't have any error recovery.

With best regards
Andreas Schweigstill

PS.: If you need a consultant which does some forensics on your failed
  products and is able to find a quick and clean(!) solution don't
  hesitate to contact me. ;-)

Then all I can do is wishing you an early and complete crash,
otherwise you will never fix the real problem until it really hurts.

Well now I had time to solve the problem once and for all. If I look back the
solution was so simple. Because we use a .bat and .tcl file to copy all on
the NAND-Flash we haven't set the active ENV-Block (one redundant and one in
use). Now I simply ad the flag set in the .tcl file and it works:

################################################################################
#  proc uboot_env: Convert u-boot variables in a string ready to be flashed
#                  in the region reserved for environment variables
################################################################################
proc set_uboot_env {nameOfLstOfVar} {
    upvar $nameOfLstOfVar lstOfVar
    
    # sector size is the size defined in u-boot CFG_ENV_SIZE
    set sectorSize [expr 0x20000 - 5]
    set flag 1                                                                    
<- I added this

    set strEnv [join $lstOfVar "\0"]
    while {[string length $strEnv] < $sectorSize} {
        append strEnv "\0"
    }
    set strCrc [binary format i [::vfs::crc $strEnv]]
    return "$strCrc$flag$strEnv"                                           
<- and the $flag
}

[U-Boot-Users] AT91SAM9260-EK: Trying to load U-Boot env from NAND

[Destrukto]

Well now I had time to solve the problem once and for all. If I look back the
solution was so simple. Because we use a .bat and .tcl file to copy all on
the NAND-Flash we haven't set the active ENV-Block (one redundant and one in
use). Now I simply ad the flag set in the .tcl file and it works:

################################################################################
#  proc uboot_env: Convert u-boot variables in a string ready to be flashed
#                  in the region reserved for environment variables
################################################################################
proc set_uboot_env {nameOfLstOfVar} {
    upvar $nameOfLstOfVar lstOfVar
   
    # sector size is the size defined in u-boot CFG_ENV_SIZE
    set sectorSize [expr 0x20000 - 5]
    set flag 1                                                                    
<- I added this

    set strEnv [join $lstOfVar "\0"]
    while {[string length $strEnv] < $sectorSize} {
        append strEnv "\0"
    }
    set strCrc [binary format i [::vfs::crc $strEnv]]
    return "$strCrc$flag$strEnv"                                           
<- and the $flag
}
