Topic: WRT54GL and 64MB RAM upgrade: [partial] success.
I have just replaced the original Hynix HY5DU281622ET-J chip with the Micron's 46V32M16-5B F (the smallest SDRAM I could find).
I expected to be having the full 64MB, but instead I have only half of that - 32MB.
My dmesg reports:
Determined physical RAM map:
memory: 02000000 @ 00000000 (usable)
on node 0 totalpages 8192
zone (0): 8192
zone (1): 0
zone (2): 0
memory: 30420k/32768k available
Is it possible to reclaim the remaining half as well?
I did not change any NVRAM variable yet.
Should I force it to recalibrate the DRAM timings?
(My WRT54GL v1.0 is SN#CLA7A0F101902)
