Hi there,


Today i received the FRDM-K22F, as it can not download the routine by J-link or OpenOCD or PEMicro. So i followed the "Quick Start Guide fro the Freescale Freedom Development Platform FRDM-K22F", when i follow the page 9 and try to enter bootload mode, but there is no drive shows, just as normal nothing happens.



    After finish this, nothing happens, and there is no removable driver, also the RGB light stops flickering. What can i do now? is there some problem with my hardware?


-Thanks in advance!
