Tool/software: TI-RTOS
Hello, I'm a beginner and I'm using ftp in my platform and this work slow (slow transfer file). I have a problem with running the cache in OMAPL138. When I use a cache without mmu my program dies after a few seconds.
I'm using ti-processor-sdk-rtos-omapl138-lcdk-05.01.00.11 with:
-> bios_6_73_00_12

Do you have any instructions to run the cache?
What am I doing wrong? Where is the problem?
