Thanks for promoting the new K3 DDRSS configuration tool (v0.12.00)! Until recently, I was still using the old spreadsheet (K3 DDRSS v0.10.0) from outdated application note [1]. The FAQ post [2] is really useful for custom board DDR configuration but somewhat difficult to find/notice on e2e forum. Note: The K3 DDRSS sysconfig based tool can even be used offline [3].
