I was wondering if it was possible to upgrade the RAM of a WRT54G from 16MB to 32MB?
My unit (v3.1) has a Hynix HY5DU281622ET-J ram chip which according to specs is DDR333 8Mx16 in a TSOP package.
I've seen that some v2.0 (XH) units featuring the HY5DU561622DT-J can use of the full 32MB provided by this chip. As the v2.0 and the v3.1 share the same CPU (BRCM 4712), shouldn't it be possible to upgrade the ram of every WRT54G >=v2.0 to 32MB by replacing the ram chip and setting the appropriate nvram variables? what's the limit imposed by the cpu/pcb design? and how could i recognize compatible ram chips?
I'm quite willing to try out this hardware mod as it would substantially increase the capabilities of this otherwise already great Linux device!
(the flash memory can already be extended easily by the well documented sd/mmc card mod)
