Hi All,

I faced some problem while booting the linux

Using tftp I copied the linux image into ram at 0x8000
after I used bootm command
at that time its working fine.

But whenever I copied the linux image into flash at 3
to 10 sectors and after I used bootm command but I
getting error message like below

## Booting image at 1c060000 ...
   Image Name:
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    997788 Bytes = 974.4 kB
   Load Address: 00008000
   Entry Point:  00008000
   Verifying Checksum ... OK
OK

Starting kernel ...

Uncompressing
Linux.......................................................
......
........

crc error

 -- System halted

In cmd_bootm command I given 3rd sector
addres(0X1c060000)of flash also.
My flashdisk file system starting at 11th sector.

Pls give me tha idea to solve the above problem.

Thanks & Regards
Srinivas Rao.Ch

Error checking data in CSV files
user name
2006-09-15 07:29:25
Hello,

I have a question regarding CSV files as a data source. So
far, I'm able
to connect and load data fine, but I am expecting some
trouble further
down the road: The CSV files are to be uploaded by the user,
and needs a
through error checking. Basically, the files can have any
problem; too
many commas, wrong data types or anything else.


If there are some serious errors in my data files, the data
loading just
fails with some very generic messages. At a minimum, I would
need to
know at what line of the CSV file the error happened, and I
would also
need to go through the file and find all lines with invalid
data, as
fixing errors one by one would take too long time.

What I want, would be iBatis working pretty much as it does
right now,
except that it would give me a list of error messages and
the line
number of each error instead of just an exception.

Is there any clever approach that might give me what I'm
looking for?
Any smart ways of validating CSV data and make iBatis make
999 objects
and an amazing error message for the single line that
failed?
 
If not, it seems that the only way to get this to work is by
writing my
own CSV parser by hand, ditching both the CSV driver as well
as the
iBatis mapper. Which would be a bit annoying (But I'll
live. At least I
iBatis will insert my objects into the SQL DB after I've
parsed them
from CSV, phew!)


My issues are maybe more related to ODBC and the
"Microsoft Text Driver"
that iBatis, but maybe someone here have any ideas, so I
hope you don't
mind me asking
