Unable to write to the SPI Flash on the LPC4370(LPC-Link2)

aroerina2 — Sat, 29 Nov 2025 23:46:07 GMT

For the past few days, I've been trying to write to an LPC4370 (LPC-Link2) using MCU-Link in the MCUXpresso IDE, but I keep getting the error “No flash configured at the specified address” and the write fails.

In the project settings, the Flash driver is set to “LPC18_43_SPIFI_GENERIC.cfx” and the Flash address is set to 0x14000000.

When I remove the Flash region and specify the code execution area as SRAM, the error does not occur and it executes normally, so I believe the connection to the MCU is fine.

Does anyone have any insights on this issue?

Hi @aroerina2

May I ask what model of external flash you are connecting to?

@Harry_Zhang

I am attempting to write from MCU-Link to LPC-Link2. The SPI Flash on LPC-Link2 is a W25Q80BVSSIG.
