Code Composer Studio Version: 7.1.0.00016

The LAUNCHXL-F28379D is fanstic, I got it last week. The demo C:\ti\c2000\C2000Ware_1_00_00_00\device_support\f2837xd\examples\cpu1\launchxl_f28379d\cpu01\Example_28379D_LaunchPad woked well.

I want to develop applications with SYS/BIOS support. I add the led blink code into the SYS/BIOS minimal project. The project worked in debug mode. But after power off and power on with the USB, the led does not blink.

please help, thank you.

Can you attach the "cleaned" project? What version of SYS/BIOS are you using?

SYS/BIOS 6.50.0.10

XDCtool 3.50.1.12_core

TMS320F28379D.cmd has been modified, the origional one adress about Ramfuncs is wrong.

Or is there any SYS/BIOS examples available for LAUNCHXL-F28379D? I can follow and find what's wrong.

Thank you.

Another example, still fail to boot from FLASH.

CCS6.2.0

Please help, I have tried with different versions of CCS and SYS/BIOS, but still fail to work.

Thanks for the project. I'm looking at it now and should have an answer by Monday.

Hi, I was able to take your project and reproduce the problem on the F28377D. Then I was able to fix the issue. You are not disabling the watchdog (Which CCS does for you via the gel file). To disable the watchdog via the Boot module, add the following line to your .cfg file. After I do this, the program worked and LEDs blinked as expected.

Boot.disableWatchdog = true;
