Hello,

 

i have develop a new embedded board with the MK22FX512VLL12. I have put a pull-up of 10kohm on the reset pin but when i try to program this micro for the first time the reset pin continue to oscillate. 

 

 

i have try with the segger commander with the command erase and unlock kinetis but nothing. I can't erase the memory. I have read some post that speak about this problem but i didn't find a solution. I use a EDU Segger Jlink.

This happen on all board

 

Thanks
