Hi,
I'm having flash erasing problem when using j-link(connect target successfully), it happens eveytime. Please help to identify the issue thanks.
I have tried set the SWD speed to 200kHz but no difference.
Hi,
Thank you so much for your interest in our products and for using our community.
The debug port pins default after POR to their JTAG functionality, please check that you have configured the SWD pins according to the Table 9-2. Debug port pins from reference manual.
An also I see that there is another post with the same error, could you please try its workaround?
Have a nice day!
Hi,
The SWD pins are configured right. I'm trying to unlock a secured MCU from our customer but failed, below is the response. Command : connect -> unlock kinetis -> erase
Do you have another way to unlock MCU? Preferably using PE micro Cyclone.
To unlock the device if Flash is secured follow the following steps:
Using MCUXpresso IDE to Unlock the Device
1. Verify Connections and Settings:
2. Check Debugger Firmware:
3. Using J-Link Commander to Unlock:
