Hello - k53n512 tower board 'brick'

rcl-arm-coder — Thu, 27 Nov 2014 12:01:23 GMT

While minding my own business and innocently trying out 'example' programs, I had 'processor expert' pop up in one of the IDE's I was

trying.

This has probably reconfigured internal GPIO assignments that control power/reset modes.

End of day, K53N512 tower board is bricked. The nice people at P + E Micro will gladly sell me (400 usd) a jlinkish debugger

and a mini app that prompts you to power up/down the board, and attempts to halt before the 'dangerous' area, and let you erase the flash.

Hey Freescale - isn't there an easier way to erase the flash and start again non-brick mode?

Thanks

Richie

Hi Richard Lowes,

The below steps could help!

1) creating a new NULL project

2) connecting NMI pin to GND before power-on and then download the created project

3) After downloaded, then, power-off and disconnect the NMI pin from GND

please let me know if it works!
