I've been unable so far to boot NetBSD on my PINE64 ROCK64 (v2.0, Rockchip RK3328) using U-Boot built with its own TPL, the default since commit ff3dd0a474.
The same NetBSD image boots fine using the binary TPL supplied by Rockchip.
The exact failure varies but it always seems memory-related. Typically the NetBSD kernel fails right after starting with a panic in its virtual-memory system, uvm.
Also significant may be these messages sometimes output by U-Boot at startup, which I haven't seen when the Rockchip TPL is used:
libfdt fdt_check_header(): FDT_ERR_BADMAGIC
I've pasted the output from a typical failed boot below and have submitted a problem report (with a bit more detail) to the NetBSD project:
https://gnats.netbsd.org/54557
Does anyone know why this might be happening? Is there perhaps some additional setup the U-Boot TPL expects from the OS to finish configuring the RK3328's memory controller that's currently missing from NetBSD?
How I can diagnose this further?
