[U-Boot] Uboot ext4write command error

[vemaa at vestas.com]

Hello,

I've a regression test case for ext4write command which writes a 100MB file
to a SD card ext4 partition continuously 1000 times.
Initially this 100MB file is loaded from the same SD card's FAT partition
with fatload command.
When i run the test case, after 800 iterations, I've got the following
errors on uboot console

(FI: 1. uboot version: U-Boot 2013.07-03530-g774dc8a (Jan 27 2015 -
12:35:52),
     2. SD card (capacity: 2GB) has 2 partitons, 1st one is fat partition of
300MB and the other ext4           partition of 700MB
     3. when i tried the same with uboot version U-Boot
2013.07-03530-g774dc8a (Jan 27 2015 - 12:35:52), it got failed at 180th
iteration)
     4. My observation: It is not related to the size of the file, even the
same error occured with a 1MB of file in the test case )

uboot ?
