CCS/CC3220SF-LAUNCHXL: Can't download, error 1170

Expert 1280 points
Part Number: CC3220SF-LAUNCHXL

Tool/software: Code Composer Studio

I have attempted in vain to download a compiled demo project to the dev board. Invariably, I get the following error:

(Error -1170 @ 0x0)

Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).

(Emulation package 8.3.0.00003)

I reset, cycled power, changed JTAG settings but nothing changes. I am just compiling one of the RTOS examples. Running on iMac with macOS 10.13 and CCS 9.2

    Hi,

    Were you ever able to download code to this board? If not, check the thread below that contains a range of troubleshooting tips for it:

    Hope this helps,

    None of the suggestions in that thread helped, jumpers were in the correct position and board was in dev mode. Also when I tested the connection with the board (project properties, test) the connection worked just fine without a single failure reported.   I did notice that a different example project (a NORTOS project) build and downloaded just fine - there appeared to be a difference between the two ccxml files. Copying the 'good' ccxml file to the 'bad' project allowed the download to work.

    1. Though I noticed the differences in the CCS GUI between the two ccxml files, there appeared to be no way to make changes. At first I thought to just put them side by side and made changes so the files would be the same and I could learn something in the process. But no. 

    2. Every time I download, my CCS perspectives layout will change. Every dang time I have to reset it. Everytime I bring up some window (Explorer for example) the layout is modified and whatever window is just plugged in the middle somewhere.
