LP-CC1312R7: How to write into external flash using Uniflash tool

while using flash-rover i am hitting following error:

C:\Users\lab\Desktop\flash-rover>ti-xflash.exe -d cc1312r -x L24000RF read 0 100
Error: Unable to find CCS root

C:\Users\lab\Desktop\flash-rover>

though I have installed CCS even i am hitting the same error.

Any pointer will be helpful.

Thanks,

Hi Bhasker,

You have to read the instructions in the GitHub repository. Indeed, flash-rover has to be copied in a specific location, inside of your CCS folder.

Only then it willl work.

Here is an example command line that writes a binary file to the flash at address 0:

C:\ti\ccs1210\ccs\utils\flash-rover> .\flash-rover --device cc1352p --xds L42001ES write 0 --input .\englishcommunication.raw

Hi bhasker,

I am sorry, I do see the same error. The reason is that the software has not been updated to support the newer x7 devices.

I will find a solution. In the meantime, you can try to modify the software as well.
