The whole boot flow is captured here[0]. See if it helps [0] https://gitlab.denx.de/u-boot/u-boot/-/blob/master/board/ti/am65x/README No, we never tried Linux on R5. But I did verify U-Boot(non-SPL) on R5 just for experimentation sake, and it works well. One hurdle I faced was that by default any region above 0x8000_0000 is marked as execute never. Need to setup right MPU configurations before jumping to U-Boot/Linux. >> >> I'll let Lokesh point to where the design of the am65x platform has >> been talked about.

I don't think anything interesting will be obtained from R5 SPL logs. Just the SPL banner and boot device. Anything specific you are looking for? I am on a vacation. If you insist, I can get logs once I am back from vacation (i.e.next week). > I see that you use SPL and also enabling booting Linux. > Are you also testing booting to OS? No. > Are you also supporting booting R5 from A53 and vice versa? Yes, R5 starting A53 and A53 starting R5 are supported.
