CCS/OMAPL138B-EP: OMAPL138

Hello,

Have you tried using a working example first? This will help us isolate whether it's a hardware or software issue. I found these examples on the web for the MityDSPL138 module:

support.criticallink.com/.../1500

Can you give the uart example a try?

By default the ARM has access to most on and off chip memory areas, including the DSP Internal memories, EMIFA, DDR2, and the additional 128K byte on chip shared SRAM. Likewise almost all of the on chip peripherals are accessible to the ARM by default.

Yes, you can program the ARM through JTAG just as you do for the DSP. Which software package is the UART_ECHO code from?

OMAPL138_StarterWare_1_10_03_03\examples\MityDSPL138\uart. This is the path of the uart code which i tried running. Before running a code do i have to do something with boot?
printing hello world i tried, modifying UART registers also i tried, both were possible.
Through JTAG why cant i access the ARM registers then ?
I will try the example what you gave too.

Please see the following page. It looks like some modifications are needed to get the examples running on the MityDSP-L138.

ARM9_0: Trouble Removing Breakpoint with the Action "Finish Auto Run" at 0xc2080a3c: (Error -1066 @ 0x3332) Unable to set requested breakpoint in memory. Verify that the breakpoint address is in writable memory. (Emulation package 8.0.27.9)

Its showing like this while debugging

I think this is an issue with the GEL file not properly initializing the device. Can you share which GEL file you are using? (Double-click on your target configuration file, go to the "Advanced" tab, select ARM9_0, and copy and paste the path in the "initialization script" field.

Please also share the console output when connecting to the Arm core.

It looks like there is a GEL file specifically for the MityDSP-L138 in Critical Link's BSP:

support.criticallink.com/.../Board_Support_Package

We're interested in just the GEL file:

Are you able to download this and add the gel file to the initialization script field?

I tried loading the gel file for ARM, but its giving error.
