Hello Champs,
1. Customer used TCI6638k2k and CCS v5.5, he wanted to use linux to load dsp .out files, he could successfully load dsp code from 0XA0000000-0Xbfffffff, but failed from 0x800000000-0xbfffffff.
2. If modifying the address to 0xA0000000-0xbfffffff, the total size of 8 .out file is about 15Mx8=120M. It sometimes prompted below error.

It seems that it is caused by memory leak, does the large size of the .out make the memory leak?
Thanks.
