LPC55S69-evk(Rev A2) cannot be flashed by onboard link2 with Jlink firmware

francisy — Sat, 14 Dec 2019 00:27:45 GMT

I bought a LPC55S69-evk(Rev A2) but it cannot be flashed by onboard link2 with Jlink firmware.

The setting was working for my Rev A1 board.

If I use CMSIS-DAP firmware for the onboard Link2, it works properly.

If I use jlink OB firmware for the onboard Link2, it can attach debugger to the board, but it cannot erase or program the chip.

I am using NXP Mcuxpresso.

Hi Francis Yeung

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
Please follow the steps which are demonstrated in the https://www.segger.com/products/debug-probes/j-link/models/other-j-links/lpc-link-2/ to update the Jlink firmware, then give a try again.

Have a great day,

Hi Jeremy,

I have done this. I am using the latest jlink OB firmware. But it cannot erase and program. However, it can attach to target and run debugger.

I do the same process on both A1 board and A2 board. A1 board works properly. But A2 board has this issue.

Hi Francis Yeung，

Thanks for your reply.
I don't have the LPC55S69-EVK (Rev A2) on hand now, and I'll apply for one board and do the same testing for confirmation.

Have a great day,
TIC

Hi jeremyzhou,

Sorry, I just release my Jlink software/driver is not the latest although the firmware of Link2 firmware is latest.

Now it is working fine. Thanks for your help.
