I’m using L4T 32.7.6 with PCN211181 overlay fully applied. We have a few U-Boot patches on top of tegra-l4t-r32.7.6_good U-Boot tag to support our product, but those should not affect U-Boot’s memory probe.
The same code can detect full 4GB on unaffected modules. The affected modules are confirmed to have D8CSC marking on the memory chips.
The full U-Boot boot log can be found here:
