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 )

******** Test case output just before fail *********** i=21 j=0 writing to file //test_write1 File System is consistent file found deleting update journal finished File System is consistent update journal finished j=1 writing to file //test_write2 File System is consistent file found deleting update journal finished File System is consistent update journal finished j=2 writing to file //test_write3 File System is consistent file found deleting ext4fs_devread read outside partition 4294967200 ext4fs_devread read outside partition 4294967200 update journal finished ext4fs_devread read outside partition 4294967200 part_offset is 1953280 total_sector is 1367232 error: overflow occurs File System is consistent no block left to assign no block left to assign ** Error ext4fs_write() ** j=3 writing to file //test_write4 File System is consistent file found deleting ** Error ext4fs_write() ** j=4 writing to file //test_write5 File System is consistent file found deleting ** DI ext2fs read block (indir 2 2)malloc failed. ** data abort

Anybody have faced the same problem ? What are the limitatons of the ext4 in uboot ? any one has fix for this ?

Any help greatly appriciated, Thanks in advance.
