CCS/TMS320F28379D: XDS100V2 USB can't connect to the target

user4669408

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

I have a problem with my emulator XDS100V2 USB. when I load the program to the TMS320F28379D then I run the program, it's ok, but after several minutes it will stop as below:

C28xx_CPU1: Error: (Error -150 @ 0x0) One of the FTDI driver functions used during configuration returned a invalid status or an error. (Emulation package 8.0.903.2)
C28xx_CPU1: Unable to determine target status after 20 attempts
C28xx_CPU1: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging

what's the mean of this error, and what's the reason for this error, and if this is caused by EMI, any solution to solve it?

then I change to XDS100V3 USB, the problem also exist.

Han,

When we see issues with the JTAG disconnecting during program execution it is helpful to understand the C2000 is still behaving normally otherwise. What I mean by this is if the C28x is still executing its program code as expected; whether it is still controlling the system correctly, or if you have a spare GPIO that can be used to determine what the code is doing.

If the only issue is the JTAG connection to the C28x, I would make sure that your connections to the JTAG pins with respect to the board layout as shown here http://www.ti.com/document-viewer/TMS320F28379D/datasheet/emulation-jtag-sprs8808282#SPRS8808282 .

Best,

Matthew

Han,

Wanted to follow up to see if you had made any progress on the above debug steps.

Best,
