lpc54s018M-EVK not being able to update QSPi flash

[HeMyFAE]

Dear LPC Tech Support,

Environment:

MCUxpress 11.2

LPC54s018M  SDK  2.8.2 

Problem:

Unable to download  and debug code on embedded QSPI flash demo code with both Link Server and Jlink.

I even roll back to MCUxpresso 11.1.1 and SDK 2.7 but it still can't write to flash.

Please advise!

Can you try ISP boot? See Section 6 (Troubleshooting) of the manual: https://www.nxp.com/docs/en/user-guide/UM11192.pdf
