Thank you for your response, it's quite clear now 🙂

I think this thread can be considered closed then. I'll create a new issue regarding mcuboot and XIP, given that diverges from the original question asked here.

Thanks for the patience Leandro, I've been sick for a few days.

[quote user="lsoria"]Is there any resource that mentions that XIP doesn't work over SPI?

I can give you the opposite. The PS of the 53 mentions that XIP is an available feature for QSPI. The section on SPI doesn't mention this.

Hi Elfving, thanks for your response!
Well, that's unfortunate :(
Is there any resource that mentions that XIP doesn't work over SPI?

Hello Leandro,

[quote user=""]Thanks in advance, and apologies if the question seems to be lazy, it's my first time interfacing an external flash on Zephyr.[/quote]

Not at all :) Please feel free to ask about anything!

Though I believe you do need to QSPI for XIP to work; you can't use SPI for this.

Regards,

Elfving
