Mass erase is disabled for k series

[jyothi_pula]

Hi All,

Using segger debug tool performed erase chip. After performing the task microcontroller got into protected mode. it isnot allowing to flash source again the showing " couldn't find the core  in coresight setup. Abort the setup."

If I browse it google it mentioned chip could be blocked. Help me to unlock the chip.

Thanks in advance.

Best regards,

Jyothi Pula.

Hi Jyothi Pula,

Please refer: How To Sucessfully Program a Custom made Kinetis Microcontroller Board.(If this doesn't work, then please try to use the P&E recovery utility mentioned in Bricking and Recovering FRDM-KL25Z Boards: Reset, SWD Clock and Low Power.)

Check the hardware circuit of your custom board.(NMI_b \ Reset_b \ debug pins)

Please download the MCUXpresso IDE, step8 can be replaced by resurrect locked Kinetis device in GUI Flash Tool.

GUI Flash Tool extended for P&E and SEGGER

The GUI Flash Tool previously was only for the LinkServer (or LPC-Link2) connections.

GUI Flash Tool

Now it supports all debug probe connections, including P&E and SEGGER, and I can program, erase or even resurrect a ‘bricked’ Kinetis device:

LinkServer GUI Flash Tool

PEMicro GUI Flash Tool

Segger GUI Flash Tool

Using the toolbar icon is probably the most convenient way to use the GUI Flash Programmer, it is possible to run it from the debugger launch configuration too:

Running GUI Flash Programmer from Launch Configuration

The operation executed is logged in the Console View:

Best Regards,
