This is an issue when using the OSELAS phyCORE-AM335x rt kernel on the 
Phytec BSP and not related to ptxdist. So this list is the wrong place 
to ask. Please contact the Phytec Support in such cases.

Your malloc space in ram is to small. You have to increase the 
MALLOC_SIZE in the barebox config.
You will face the same problem when trying to flash the image to NAND or 
SPI NOR flash. You
will have to increase the partition size in the environment and also 
update the rootfs.
