lpc55s69 can't be programmed

steffen_norbert — Tue, 04 May 2021 17:46:36 GMT

We have produced a custom board for the lpc55s69 chip (100 pin HLQFP). For power supply , USB and connectivity, reset, the JTAG connector and quarz oszillators we reproduced the design from the EVK development board. The processor seems to run, but we are not able to program it (using MCUxpresso 11 and the Link Probe from the EVK board). From several tries ("Debug" with the Hello world example) 2 times the programming went through and we ended up at the breakpoint (first line in main). we never managed to get "Hello World" over FC0.
The error messaged whch where shown in the Console window of MCUXpresso are shown below. We felt that using the GUI Flash tool doing a mass erase helped some how, but did not really solve th problem.

Any help how to get more information what happened and why is very much appreciated.

Thank you for contacting us.

Your custom board can't be connected with LPC-Link2. The problem may be in either PC side or board side:

1. test your LPC-Link2 with another board. make sure your LPC-Link2 is in good condition.

2. create a NEW project in a NEW workspace, make sure the problem is not due to SW association.

3. refer this article to check your debug interface design.

Hope this helps,

Hi,

thanks for the suggestions. Meanwhile we found a hardware Problem. Once we solved this we hope our custom board will work. If not we will come back.

tx & regards,

Steffen
