make model micro soldering tutorials? i would really really like to fix this if i can. I think the size should be the same of the one needed for the buzz fix... about soldering eee... good luck! :P I made my buzz fix and it was a pain in the a**hole! [0) check your pcb and verify you still have the traces where you'll put the new resistor because maybe you ripped the metal out] 1) remove the board from all the plastic case 2) firmly fix it to a solid table with an adhesive tape 3) do not drink alcohol and keep calm ;) 4) use the sharpest newer soldering tool, 25W-30W 5) put a _little_ of alloy on the little squares of the pcb 6) put the resistor in place and keep it _gently_ pushing down with a small tool, like the point of a pin or similar (gently, otherwise you make it jump away!) 7) take your iron and pick up some but _little_ fresh alloy on the tip and then melt it on the first side of the resistor 8) do the other side of the resistor 9) verify that your resistor is firmly in place and you haven't leaked the alloy around and check any short-circuit the size is really tiny, so good luck and don't panic! you can put your resistor in any direction, it hasn't +/- polarity. be quick with the iron on your components otherwise you'll fry them! no more than 2-3 sec. you can cool down the components and do another try little later.

It will probably take a u-boot expert or a close look at the code to see what the error means, and possibly sight of the glamo documentation :-( It seems like a hardware error to me, though there's a faint possibility it's got into some odd state that's being kept alive by the backup battery. All I can suggest at this point is to check the contacts on the SD and its socket are clean, and try leaving it with the battery out long enough for the backup battery to go flat before trying again. I don't know how long that takes, but over night should be plenty. If it was long enough the rtc will have lost the time.

I can say mean exactly, i know following bugs: 1. u-boot 2-4-2 need fix to read kernel from sd, but kernel works perfect with this timings (never saw single read failure). 2. kernel can't access sd without large delay and this delay is different in different versions. but u-boot can access data instantly! Also, i know following things which is probably bugs: 3. sd card init in kernel look strange. some mess with voltage, some delays. Need investigation. 4. sd card read speed is somehow 7 times slower than for same sd card on host. glamo-sd bus is 4 bit, same to host as far as i understand. no idea why it should be so much slower. card read speed bottleneck is _not_ cpu- glamo bus or glamo-sd bus. Need more investigation, but entirely possible it is just something wrong with driver/hardware setup. 5. yes. supported and unsupported look strange and i do not believe glamo 'works' with some cards and do not with others.
