Tricky problem. Is this for a custom board or an existing configuration? If an existing configuration, which one? If it's for a custom board, then the place I would recommend to check is the linker script, Kconfig options, and compiler options. Perhaps try to find an existing configuration in the NuttX tree that is as close as possible to yours, and compare the various files (linker files, defconfig, etc) and see whether any differences that you find will affect heap allocations. Hopefully someone else here can chime in with some more specific items to check. Nathan
