nRF5340, nRF7002, XIP, MCUboot, filesystem -> Any examples?

[khelmutlord]

Hello,

I am attempting to configure the following setup to support (with an nRF5340 + nRF7002-EK)...

1. nRF7002 on SPI w/ TLS, STA, and FW patches offloaded to QSPI XIP

2. nRF5340 without any BLE support, empty netcore

3. LittleFS also on external QSPI flash

4. Storing particularly heavy libraries in QSPI XIP.

Is there a simple way to ensure that XIP application code can operate concurrently with the file system? Is partition manager helping things here or can I use the static partitions in Zephyr?

Here is my current project: github.com/.../nRF7002-XIP-Filesystem. When SB_CONFIG_WIFI_NRF70=y is enabled, I get the following error: 
ninja: error: '_sysbuild/nrf70_wifi_fw_patch_target', needed by 'dfu_application.zip', missing and no known rule to make it

If this is disabled, I am able to at least boot but, of course, cannot communicate with the nRF7002.

Thanks,

Helmut Lord

Hi Helmut,

I got a colleague who I maaaaybe think has an example that can help here, but he is out of the office today.

I will get back to you next week when I have talked to him.
