Hi:

MCU: LPC54018
BOARD: LPCXpresso540xx Eval Brd Rev E

Problem: can't program the flash，the error log from MCXpresso IDE is：

"chip initialization failed - Ef(34): Timed-out initializing flash.

failed to initialize flash driver LPC540xx_SPIFI_SFDP.cfx"

the eval board can run the demo download before which compiled by myself.

how can i fix it?

Hello ,

Please show your steps how to download and debug your project?

Also first use a SDK demo to test.

Hello ,

How about Remove JP5?
