Strange that why it is made a "solder" jumper
<zyp>
you could remove both and solder a header to J5 for a normal jumper if you'd like
<zyp>
I figure the reason it's using a solder jumper by default is because all the other parts are surface mount, so the board only requires reflow soldering
<zyp>
adding a selective wave soldering step just to solder J5 would increase the cost of manufacturing significantly for little gain
<zyp>
or more likely hand assembly than selective wave, but still

zyp how is the SDRAM on ulx3s different compared to the DDR3 memory on orangecrab in terms of memory data transfer protocol implementation?
<zyp>
slower and simpler, I guess

DDR3 has DQS strobes, you need to make use of special fpga features to implement that properly. SDRAM (and DDR1) you're good with just IO registers.

ive been digging thru ddr2 docs lately, to better understand the dram controller in the rpi
<clever>
and now i know more then i wanted to know, lol
<clever>
now i cant stop thinking about how i would implement suspend to ram and deal with self-refresh, without halt the docs.....
