Well, even the tiniest check with the source  code  would  have  con-
firmed  what you could expect from the "ERROR : memory not allocated"
error message: malloc() resp. realloc() return error codes.

This sounds not really unlikely when you try running nested shell
scripts, which may need to allocate some data.

Well, but the solution is trivial: increase the size  of  the  malloc
arena  in  your board config file. Many boards define this as 128 kB,
which is enough for standard use in most cases, but in your case more
is needed.

There are two completely separate topice.

"setenv" is a native U-Boot feature. I don't know of  any  issues  in
terms  of  memory  allocation, especially as "setenv" itself does not
allocate any new memory.

The hush shell is borrowed from the BusyBox project; you  might  want
to raise your concerns there.
