ext4load failed in the uboot

[Kali]

Hi guys:
    I'm kali.

We used  this uboot(PDX-License-Identifier:GPL-2.0+) on the rtl11619b soc.

We find sometimes  ext4load failed.  cmd is "ext4load mmc 0:4 0x1400000 emmc.uImage".

I guss  global vars cause this problem. Maybe,global vars  are modified by other app.

for example:

    static block_dev_desc_t *fs_dev_desc;  static disk_partition_t fs_partition;( they are included fs.c)

    struct ext2_data *ext4fs_root;struct ext2fs_node *ext4fs_file; uint32_t *ext4fs_indir1_block;( they are included ext4fs_common.c)

    Please check it. Thank you!
