After trying different succeful tests programs for the TWR-K40x256 with the debug in codewarrior, I tried to put my program into the Kinetis using the "Flash programmer" (blue lightning) without success (I did this to make to program work without using the computer). Maybe I did something wrong because now I'm not able to use the debug anymore. While downloading the program into FLASH (by the green bug), codewarrior says that he is downloading, but it's still stuck at 99% saying "downloading binary to target".
I clicked on "erase whole device" into the flash programmer menu, maybe the problem comes from that point ?
Now I'm unable to use the MCU which is impossible to make it work.
Sorry for my english, I'm registered with my team for the french qualification of the freescale cup and we can't continue the preparation with this issue.
