TMS570LS programming issue

Other Parts Discussed in Thread: HALCOGEN, TMS570LS3137

Hi,

I made one sample program for glowing LED (TMS570LS3137, Dev board TMDX570LS31HDK) using HALCogen and compiled using CCS.

Since i am not able to connect debugger to CCS, the "gio.out" file is flashed using nowFlash v3.42(-bl -er -pr -ve "C:\workspace_v5_2\GIO_Test3\Release\GIO_Test3.bin" -r 0x00000000-0x002FFFFF,0xF0200000-0xF020FFFF -q -emu TIXDS100V2 -p 000 -cpu CORTEX_RXX -targets 1). This programs runs successfully.

Now the problem is, i am not able to flash another program to ECU. Even "hercules safety ecu demos" software loading not happening. The first sample program flashed runs after each reset.

Regards,

Shanavas

Hello Shanavas,

Are you able to erase the flash using nowFlash?

I have successfully compiled the Blinky example, LED Blinking wtih 1 HZ. In Debug mode, I can run the application, and the LED is blinking.

But with nowFlash using the Settings above, after execute, there are no errors displayed, but the LED is not blinking.

I need this tool since I want to test the same Application written and compiled with Ada.

What settings are missing in NowFlash which is internally used in CCS Debug mode?

From CCS, can you do a system reset and then see if you can connect to CPU? System reset does not require connection to CPU.

You may consider replacing the instruction at address 0x0 with "b #-8" for debugging. After reset, CPU will loop around this location. When you hooked up CCS, everything is at default.

Thanks and regards,

Zhaohong
