I cannot confirm this as I do not have the hardware to test. But ...

the issue is probably the insufficient malloc area size defined in
the board config file. The mx51evk defines CONFIG_SYS_MALLOC_LEN
to be slightly more than 2 MiB. The vision2 config sets
CONFIG_SYS_MALLOC_LEN to 10 MiB. Please try increasing CONFIG_SYS_MALLOC_LEN.

Thanks,
Anatolij
