Hi, All:
I use ccs uniflash Version: 3.2.0.00123 to download camera application to TI demo baords. I running on windows 7. At beginning, I can format and download image. But I don't know why now down load failed. The log showed "---- reading ACK signal failed ----".
I push the reset button when pop "--- please restart the device ---", it does't work.

hI, Shlomi:
It's ok now.

Hello Shlomi,
I have a CC3200 Launchpad that is suffering from similar symptoms. Thank you for posting such a comprehensive testing protocol. I have gone through all of the steps that you have mentioned here and I have verified that FTDI is functional (via step 4) and I have confirmed power levels (via step 5). However, I am still unable to connect to the board and upload a new program.
I have a suspicion that it might be related to the last program that I loaded to the board. In that program, I configured pins 3, 4, 15-18, 20, 45, 50, 52, 53, 55, 57-64 as GPIO output pins and pins 1,2, and 19 as PWM pins each associated to a different timer. My concern is that in configuring all of these pins as GPIO outputs, I may have overwritten one of the pins necessary for programming. Alternatively, there may be a different problem that I am unaware of.
Any help or advice you can provide is appreciated.
Thank you
