Hi Alice,

Actually I was trying with the demo projects. The issue got resolved due to the technical team support. Thank you for the support.

Hi,

Again after unlocking the device, initially i was able to debug with the examples programs. After doing with some changes in the program, if i execute the same program, i will get the error as "Error: Failed to erase sectors 0 @ 0x00000000 (Algo35: Flash protection violation. Flash is write protected" and if i download the different program and try to debug then i will get the error as "Error while programming flash: programming failed".

Can you please suggest me what would be the problem.

Thanks and Regards,

Hello SHRUTHI N A,

What about your project, please check whether your code project the flash to erase and write.

How about a simple demo project? You can also share your project.

Hi,

Thank you for the update Alice.

I had been browsing the net to find the solution for the problem and found the solution in the below link:

https://mcuoneclipse.com/2014/10/05/unlocking-and-erasing-flash-with-segger-j-link/

But i was getting the same problem as unable to write in the flash since flash is write protected. So i use to follow the above for unlocking the device but i didn't erase the flash.

After unlocking the FRDM-K64F for 3 to 4 times, now i am getting the problem as "Error while programming flash: Programming failed and now if i unlock the FRDM-K64F.. FRDM-K64F will be in continuous reset mode.

I am unable to continue my work. I am not able to figure out the problem. Can anyone help me with this.

Thank and Regards,

Shruthi N A
