Please detail 32M situation
Using the 16M uboot image to be sure, I see:
============================================
Ralink UBoot Version: 3.6.0.0
--------------------------------------------
ASIC 5350_MP (Port5<->None)
DRAM_CONF_FROM: Boot-Strapping
DRAM_TYPE: SDRAM
DRAM_SIZE: 256 Mbits
DRAM_WIDTH: 16 bits
DRAM_TOTAL_WIDTH: 16 bits
TOTAL_MEMORY_SIZE: 32 MBytes
Flash component: SPI Flash
Date:Jan 9 2014 Time:18:11:05
============================================
icache: sets:256, ways:4, linesz:32 ,total:32768
dcache: sets:128, ways:4, linesz:32 ,total:16384
##### The CPU freq = 360 MHZ ####
estimate memory size =16 Mbytes
I read that the 32M requires some hardware modification, but perhaps I already have it? Linux (OpenWRT) boots and sees only 16M, but perhaps that is because uBoot told it that. I must boot OpenWRT failsafe, or I get OOM errors, having 11Mb used while booting.
Unless you made the hardware modifications yourself the device will not have the larger memory.
