Hi,
I've got great working Linux on LCDK and on my custom board. As I understand linux works just with ARM processor.
Now I want to work with ARM and DSP in Linux. For example ARM recieved some data from McASP, then I send it to DSP, DSP processed this data and send it back to ARM.
Is there some manual on this subject, or I can work with DSP only from CCS?
p.s.
Linux is from mcsdk.
Hi Alex,
Yes, It is possible through SYSLINK.
Please refer the following TI wikis.
http://processors.wiki.ti.com/index.php/MCSDK_OMAPL138_User_Guide_Chapter_Exploring#Syslink
http://processors.wiki.ti.com/index.php/SysLink_Install_Guide
hi, again.
I found syslink_2_21_01_05 folder in mcsdk.
I should edit products.mak but I don't know where I can find needed folders.
I downloaded syslink_2_21_03_11 from this link
http://downloads.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/syslink/2_21_03_11/index_FDS.html
but there was no anything exept syslink.
I've got such list:
DEVICE = _your_device_
DEPOT = _your_depot_folder_
######## For OMAPL1XX device ########
else ifeq ("$(DEVICE)","OMAPL1XX")
LINUXKERNEL = $(DEPOT)/_your_linux_kernel_install_
CGT_ARM_INSTALL_DIR = $(DEPOT)/_your_arm_code_gen_install_
CGT_ARM_PREFIX = $(CGT_ARM_INSTALL_DIR)/bin/arm-none-linux-gnueabi-
IPC_INSTALL_DIR = $(DEPOT)/_your_ipc_install_
BIOS_INSTALL_DIR = $(DEPOT)/_your_bios_install_
XDC_INSTALL_DIR = $(DEPOT)/_your_xdctools_install_
I could edit just this 4 lines
DEVICE = OMAPL1XX
DEPOT = /home/user/ti/
IPC_INSTALL_DIR = $(DEPOT)/ipc_1_25_03_15
LINUXKERNEL = $(DEPOT)/mcsdk_1_01_00_02/board-support/linux-3.3-psp03.22.00.06.sdk/kernel
So I've got 2 questions:
1. I've got compiler, which I generate Linux kernel.
I can edit this line
CGT_ARM_INSTALL_DIR = $(DEPOT)/arago-2011.09/armv5te
but there will be an error in the next line
CGT_ARM_PREFIX = $(CGT_ARM_INSTALL_DIR)/bin/arm-none-linux-gnueabi-
in bin folder I've got just arm-arago... files.
Should I edit this line like this:
CGT_ARM_PREFIX = $(CGT_ARM_INSTALL_DIR)/bin/arm-arago-linux-gnueabi-
Or should I search for another compiler?
2. Where can I find folders for this lines?
BIOS_INSTALL_DIR = $(DEPOT)/_your_bios_install_
XDC_INSTALL_DIR = $(DEPOT)/_your_xdctools_install_
Thanks.
Hi Alex,
This is the file I have modified for own syslink build.
Please create new thread if any follow questions.

# Enabling SYSLINK_BUILD_DEBUG enables runtime assertion checking and makes

# SYSLINK_BUILD_OPTIMIZED is intended to be used in a closed system where all
# code paths are known, and error conditions are ensured never to occur - so
