I've had the AM437X processor for a while, swapped my design for an "S" version of the processor and tried loading my original, working U-boot-spl. It doesn't seem to work. Are these processors not code compatible?

Hello Bryan,
From "Figure 6-1. Device Nomenclature" in AM437x datasheet
"S = High-Security (AM437xHS) device, Secure Boot Supported"
The SPL needs to be signed in order to boot on HS device.
For more detailed information on AM437x secure SDK, EVM, collaterals, fill the request using the following link
