Part Number: LP-CC1312R7
Other Parts Discussed in Thread: UNIFLASH, CC1312R7, CC1312R

CC1312R7 contains 12MB external flash, i want to write some data using uniflash tool, I am getting some error "memory map prevented reading".

Can we use uniflash or some other tool to write to external flash?

Thanks,

Bhasker

    Hi bhasker,

    You cannot use Uniflash, but you can use flash-rover, for that purpose.

    You can download it there: https://github.com/ti-simplelink/flash-rover/releases

    Please use that thread for reference: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz-group/sub-1-ghz/f/sub-1-ghz-forum/868875/launchxl-cc1352p-needing-an-oad-example/3221702#3221702

    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,

    Bhakser

    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

    Regards,

    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.

    Regards,

    Arthur
