Reading ACK Signal Failed on Energia and Uniflash

Other Parts Discussed in Thread: CC3200, ENERGIA, UNIFLASH

Hello,

I've been using the CC3200 for about a week now

This is a problem I've been facing only after installing FTDI drivers for CC3200 for Energia.
When I first connected SOP2 to J8 and connected the LP to my PC, None of the LEDs glowed.

Every time I try to Upload a code in Energia, all the LEDs glow faintly I get an error saying
Opening \\.\COM30
Read ACK failed
Failed to trigger bootloader

When I try to Format it using UniFlash, the error is as follows;

[16:38:34] INFO: setting break signal
[16:38:35] INFO: detecting FTDI for device reset
[16:38:51] ERROR: ---reading ACK signal failed---

And when I try to download a code using IAR Embedded Workbench, I get the following error;

Fatal Error : JTAG initialization failed0x000000001

I've tried all of these procedures by replacing SOP2 and J8 to their original positions as well, but nothing seems to work
Please help me out with this problem!
Thank you!

  • At least the RED LED on the programmer side should turn on. Did it work work with UNIFLASH before you installed the FTDI drivers? What drivers did you have installed?
  • When I connect it to the PC or try to format it using UniFlash, none of the LEDs light up.

    But when I try to Upload a program using Energia, the DBGENn LED (D2) glows brightly, and the rest of the LEDs glow very dimly. 
    Then it gives the error "Failed to Trigger bootloader", yet the LEDs continue to glow.
    If I press RESET, all the LEDs glow brightly for the duration of time the RESET button is pressed down

    I had installed the recommended FTDI drivers from
    http://www.ftdichip.com/Drivers/D2XX.htm

    And my device is detected in the Device Manager under Ports (COM30)

    Initially I was using IAR Embedded Workbench to program the LP, and it worked great then.
    I wanted to switch over to Energia, so I installed Energia along with its recommended drivers from
    energia.nu/files/cc3200_drivers_win.zip

    After I had shorted J15(2) and J8 as instructed on the site, I connected the LP to my PC and none of the LEDs glowed.

    After that when I tried to revert to IAR workbench, it gave me the JTAG error.

    Thank you so much!
    Hope this helps!

    UPDATE : I Installed FT_PROG, and the LP is detected by it. I'm attaching the screenshot below.



  • Hi,

    Try at another PC and see if the same error happens. There is a troubleshooting guide for "reading ACK signal failed" at the link below.

    processors.wiki.ti.com/.../CC31xx_&_CC32xx_FAQ

    Try also using removing all installed FTDI drivers using FTClean, and then start again with CC3200 Guide.

  • Hello everyone,

    I've been a massive idiot and connected the wrong jumpers. I replaced them to their original state, and they're working fine now!

    Thank you all so much for your help!
