Programming boot code to external flash for LPC54018

Hi,

I'm planing for a LPC54018 with an external flash connected on the EMC.

Is there support in the circuit for any ISP and or IAP to program an external flash?

Is there otherwise any tools with support for that? (I've looked at Flashmagic but they don't seem to support the

LPC54018-series) Do you have any sample code for building BootROM functionality?

Best Regards,

Göran

I suggest you refer this article of How to boot from the external flash for LPC54018

Have a great day,

Hi,

Thanks for your answer, but that article doesn’t handle programing of external flash memories connected to the EMC as far as I can see.

Has the Segger software build in functionality to handle truly external flashes as well? (on the screen shoots I can see no reference to that or setup for that)

Regards,

Göran

do you mean parallel nor?

By checking, we don't have programming tool for it.

for external memory, we suggest use spifi FLASH.

Have a great day,
