Hi all,

 

I have a custom board which has a MK22FN128VLH10.

On uVision V5 with J-Link, I'm trying to flash a sample program but fails as follows:

 

Target info:
------------
Device: MK22FN128VLH10
VTarget = 3.270V
State of Pins:
TCK: 0, TDI: 0, TDO: 0, TMS: 1, TRES: 1, TRST: 0
Hardware-Breakpoints: 6

Error: Flash Download failed  -  "Cortex-M4"
Flash Load finished at 15:29:08

 

I think MK22FN128VLH10 has 128KB flash which address is from 0x00000000 to 0x0001FFFF.

However, according to above messages, flash writing seems to be uncompleted.

May be I have something mistakes on settings, I'm still uncertain them.

Could someone advise me to solve the issue ?

 

 

 

 

Thanks in advance.
