0001-Add-Olimex-iMX8MP-SOM-EVB-IND.patch does not apply

[JSmitNortech]

The patch contained in recipes-bsp/u-boot/u-boot-imx/0001-Add-Olimex-iMX8MP-SOM-EVB-IND.patch does not apply successfully on the Kconfig file in arch/arm/mach-imx/Kconfig of the u-boot-imx repo (branch: lf_v2024.04).

Can you rebase the patch and send a PR to fix that?

[JSmitNortech]

I am attempting to implement a fix. However, I am not YOCTO expert.

I am currently using this layer to build the Mender image for the Olimex iMX8M Plus dev board (meta-mender-community), which implements its own changes to the u-boot-imx recipe. Is there a way I can test the u-boot-imx recipe compilation without the changes that the meta-mender-community layer implements?

[otavio]

Absolutely, You just need to remove the layer from the bblayers file.

I managed to update the patch locally and it is currently applying successfully. However, the compilation step fails with this error:

| /usr/src/debug/u-boot-imx/2024.04/drivers/usb/gadget/f_mass_storage.c:688:(.text.sleep_thread.lto_priv.0+0xf0): undefined reference to `dm_usb_gadget_handle_interrupts'

Digging through the compilation logs, it seems this function is undefined at various points in the u-boot-imx codebase. However, I only get this error when building for the Olimex board. Using the same layers for a standards imx8mp-evk build does not yield these errors. So I believe there is likely a configuration issue for the Olimex imx8mp dev board.

[otavio]

Yes, probably the USB gadget support needs to be enabled.

Actually, CONFIG_DM_USB_GADGET is not needed. I rebased the patch.

I fixed this issues and I opened a GitHub PR for branch master: #308

My pleasure, please ping me in any related to this board GitHub issues. I have the hardware and I can assist. Btw I have also ported Mender and RAUC as software update solutions for Olimex i.MX8MP SoM and evaluation board.

Best regards, Leon
