Hi all,
I am using a FRDM KL05z (eval board) to program a custom board with the KL04. I've configured the FRDM board to operate as a external device programmer/debugger utilizing USBDM OpenSDA files. Whenever I make my connections from the FRDM KL05z board the Flash Programmer tool (from USBDM) sees the device, but cannot program it. I am getting an error message: Programming of the Target Flash Fails. Is there a particular reason for this behavior?
The USBDM Flash Programmer sees the device as presented below:
Hi Anhkhoa,
Unfortunately the FRDM-KL05 has a hardware design bug that renders the external programming interface useless unless modified.
I think that this may have been fixed in a later board revision.
J6 as shown in the following diagram disconnects SWD_CLK (a signal from the programmer) from the external connector - It should just isolate the on-board processor.
There are three solutions:
