LPCXpresso54608 / OM13092 ISP mode

[mirceaudrea]

Hello,

I have a LPCXpresso54608 / OM13092 board and most probably I wrote the CRP incorrectly.

I get: Failed on connect: Ep(01). Target marked as not debuggable.

I need to erase the flash and regain debugger control. 

I tried to use Flash Magic with onboard LPC-LINK2(reset button +ISP0/1/2) on the serial port provided by it, but it cannot connect (cannot autobaud error).

Does the serial port on J13 connector provide ISP capabilities?

Is there another way in order to un-brick it?

Best regards,

Mircea

Hi Mircea Udrea,

Thank you for your interest in NXP Semiconductor products and the opportunity to serve you.

Please refer to the attachment to assure the MCU enter the ISP mode successful via properly hardware configuration.

And I'd like to suggest another way to 'release' the LPC54608.

First, you should update the on-board LPC-Link2 with the JLink firmware,

then follow the Fig1 to work it out.

Have a great day,
