Temat: Wymiana RAM w TD-W8970 v1.2
Zachciało mi się rozbudować pamięć tytułowego sprzętu, głównie dla zabawy i sprawdzenia, czy da się przelutować pamięć BGA z kości SO-DIMM bez sit, kulek czy pasty. Okazuje się, że się da i sprzęt działa, ale wykrywa tylko połowę ze 128MiB.
Pomyślałem sobie: bootloader, więc podszperałem trochę i znalazłem ten link. Ściągnąłem, zmieniłem w konfigu RAM na 128 oraz procesor i pamięć na 600 i 300MHz, skompilowałem i dupa:

Użyłem pamięci Samsung K4T1G164QF-BCF7, takiej samej jak w ruterze BT HomeHub 5.0 Type A, który ma identyczny procesor.
Zastanawia mnie linijka DDR size from 0xa0000000 - 0xa3ffffff. Wynika z niej, że w systemie jest 64MiB ramu i to przed U-Bootem. Czyżby więc nic z tego?
