Hello,
I finally got the chance to test it on the hardware, I have set the "CONFIG_INTEL_STRATIX10_RSU=y" as suggested and copied the libraries for the RSU to the SD-CARD.
The flash image was built with HPS first, following the instructions for creating multiple section in the flash for the FACTORY_IMAGE and the INITIAL_IMAGE.
Trying to boot with this flash image and the RSU enabled, creates the following boot error in u-boot:
Invalid bus 0 (err=-19)
Failed to initialize SPI flash at 0:0 (error -19)
RSU: Remote System Update Status
Current Image : 0x01000000
Last Fail Image : 0x00000000
State : 0x00000000
Version : 0x00000202
Error location : 0x00000000
Error details : 0x00000000
Retry counter : 0x00000000
RSU: Sub-partition table 0 offset 0x00910000
RSU: Sub-partition table 1 offset 0x00918000
Invalid bus 0 (err=-19)
RSU: SPI probe failed.
The output of the "dm tree" in u-boot (the spi does not seem to be binding/loading):

for reference, the map file of the flash image is the following:

FACTORY_IMAGE 0x00110000 0x0090FFFF (0x0017BFFF)

P2 0x02000000 0x02FFFFFF
P3 0x03000000 0x03FFFFFF
I have searched online for solutions and came across this post with similar error message...
Note that booting with a "normal" flash image (without the RSU feature) still works but of course the original issues still persist:
librsu: librsu_misc_get_devattr(): error: Unable to open device attribute file '/sys/devices/platform/stratix10-rsu.0/spt0_address' [LOW]
librsu: librsu_ll_open_qspi(): error: Unable to open '/dev/mtd0' [LOW]
librsu_init return -2
Are there other configurations that need to be change to support RSU? maybe u-boot .config file or the device tree?
thank you!
