Hello Vijay,

What tool chain are you using for the programming? ICDI? JTAG?

Hello Ralph,

I am using CCS4 Tool chain, EK-LM3S6965 board has inbuilt debugger and this is is being used to flash the code.

Earlier I have flashed the code, but after changing the CLOCK to PLL and flashing this code later i am not able to flash any code.

Regards,

Vijay

Hello Vijay,

Thanks, the board was the big one I was looking for. This should be simple to solve then! Please download our LM Flash Programmer software if you do not have it: https://www.ti.com/tool/LMFLASHPROGRAMMER

In there, select the Quick Set for LM3S6965 Ethernet Evaluation Board.

Then go to the Other Utilities tab and the second feature is "Debug Port Unlock". The device you have is a Fury device so select the first option for Fury class devices and then click the Unlock button and follow the prompts.

That will clear the bad clock configuration and allow you to program the board again.

Hi Ralph,

Thanks a lot for quick resolution, will check and revert back on this.

I have one more issue related to OLED display, previously loaded all samples related to display (Example hello program) but I am not able to see messages on the OLED. Hoping you would provide quick resolution. I have EVK-LM3S6965-D

Regards,

Vijay

Hi Vijay,

Unfortunately for that question I cannot really help. We do not sell or support the EVK-LM3S6965-D anymore, haven't for a long time. That kit predates me by a few years and I don't have one that I can test with. Sorry.

For new kit with an LCD display, we have the DK-TM4C129X or you can BoosterPack to use with TM4C LaunchPad's: https://www.ti.com/tool/BOOSTXL-K350QVG-S1
