Greetings,
I'm working on an OMAPL138 on a Critical Link evaluation board. We are eventually using a custom board with kernel version 3.2 so IPC 3 is not an option for us. I am having issues loading any program to the DSP core. I've attached the log result. I am not familiar with the details of the log, as far as I can tell I feel like it may be an issue with the Syslink build? The current program I am loading is the typical SYSBIOS example built into CCS6 for the C6000. I have made no changes other than the config.bld and updating module settings in app.cfg to support Syslink.
Attached files:
"arm_ipc.c" - the program I am running on the ARM core running a modified Angstrom Linux with v3.2 kernel
"screen.log" - log from the TRACE output when trying to load a program to the DSP core
"config.bld.cfg" - platform build (added .cfg to allow for upload via forum post)
"app.cfg" - ARM project configuration
I've appended the following to boot arguments for the system:
mem=32M@0xc0000000 mem=64M@0xc4000000
Environment/versions:
BIOS 6.34.02.18
IPC 1.25.00.04
Syslink 2.21.03.11
TI_CGT_C6000 7.4.1
XDC 3.24.05.48
Any help would be appreciated.
Thank you
Hitesh Patel
