CCS/CC1310: Having trouble programming E70 Ebytes that contains CC1310

CC1310: setting up launchpad to program an ebyte E70 915T14S

Part Number: CC1310
Other Parts Discussed in Thread: UNIFLASH

I have seen many posts on the forum trying to program Ebyte parts

I am trying to do the same using an E70 915T14S, which uses a cc1310 device

I have connected

VCC (3.3V) and GND

TMS TCK and RESET_N

When attempting to flash, I get the generic error

Error connecting to the target:
(Error -241 @ 0x0)
A router subpath could not be accessed.
A security error has probably occurred.
Make sure your device is unlocked.
(Emulation package 9.8.0.00235)

I only knew to connect the above by other posts on the forum, I cannot find any documentation, describing how to connect the CC1310 launchpad to program another device

All help appreciated.

    Hi Lee,

    To debug the CC1310, the connections to be made are mentioned in the post. Make sure the contact is proper.

    But maybe the debug interface is locked. If it is okay in your case, you could try a mass erase to unlock the interface.

    Regards,

    Hi Sid,

    Actually, I don't need to debug, I just need to flash the device.

    Would the absence of a mass erase give the error message I provided earlier ?

    If so, could you provide a pointer in order to perform a mass erase, I am attempting to flash, directly from code composer

    Is it possible to perform the mass erase from code composer, and finally - are there any additional hardware connections required to perform a mass erase

    Thx

    Lee

    The error message you provided earlier seems like an issue either with the connection itself or it says "Make sure your device is unlocked".

    For security reasons, mass erase is the only way to unlock the debug port. This does not need additional connections. 

    You can use Uniflash :https://www.ti.com/tool/UNIFLASH to perform Erase Entire Flash(Mass Erase), this should unlock the device.

    But if this does not work, then it must be a connection issue. Have you also tried what the thread you mention suggests? Also, please check if EByte themselves have some support. 

    Regards,

    Sid

    Just a short note for anyone with a similar issue

    It appears that the E70 is indeed locked, using the UNIFLASH to perform a mass erase - solved my issue

    I was then able to download from code composer
