PacManPlus Posted April 17, 2019 Author Share Posted April 17, 2019 (edited) ...and thank you so much Mitch for looking at it as well. I couldn't see anything that clearly either (getting old is a b*t*h) , and I actually was just going to toss it. Crossbow talked me into holding on to it, so I asked him to look at it. Thanks guys, so much Bob P.S. Speaking of getting older, not looking forward to my B-Day this year... I turn the big 5-0.

jaybird3rd Posted April 18, 2019 Share Posted April 18, 2019 Bob and me turn 50 in the same month, so does someone else on these forums. (Actually, I'm only about seven years behind you.) I'm glad to hear that you got your CC2 fixed! I thought I had bricked mine with a bad firmware update shortly after I got it, so I can imagine how much of a relief it must be to have it back! 2 Quote Link to comment Share on other sites More sharing options...
PacManPlus Posted April 18, 2019 Author Share Posted April 18, 2019 Curiosity Question: Is there such a thing as a Micro SD -> MMC adapter? (NOT SD/MMC but MMC only, as you guys know the CCII uses this and it's thinner than SD/MMC cards) I'd like to start using Micro SD cards, and from some of the googling I've done, it *seems* to use the same 3.3 volts as the MMC card slot... In fact most of the pins are a 1:1 conversion, with the exception of a missing Ground pin (there seem to be two of them). I tried searching Google for one, but as you can probably guess, all of the common Micro SD -> SD/MMC adapters show up. Thanks, guys Bob Quote Link to comment Share on other sites More sharing options...

Thanks, guys Bob I don't know that I've ever seen a direct adapter, because MMC is thinner making that difficult. However, the interface is the same, so if you can wire an SD card slot where the MMC slot is, you can convert it. SD was just Toshiba adding on encryption capability to MMC. There would not be any such thing as MMC to Micro SD adapters, as those two things didn't exist in the same time frame. EDIT: I stand (sit) corrected. Is this one? https://www.amazon.com/microSD-Adapter-Reduced-Size-MultiMediaCard-EverDrive/dp/B00AZEUCZY (Probably not, it is RS-MMC, not normal MMC) Edited April 19, 2019 by R.Cade Quote Link to comment Share on other sites More sharing options...
CPUWIZ Posted April 19, 2019 Share Posted April 19, 2019 RS-MMC just means "reduced size", which means it is shorter and not suitable for the CC2. Well, maybe if you plan on leaving it in forever, it may be okay. Quote Link to comment Share on other sites More sharing options...
HammR25 Posted April 19, 2019 Share Posted April 19, 2019 Some people have used the RS-MMC with their CC2 because there's less chance of breaking the card slot with one of those. They can still get them out using the adapter. Quote Link to comment Share on other sites More sharing options...

So, Bob, get one of those, what could go wrong? 1 Quote Link to comment Share on other sites More sharing options...
+-^CrossBow^- Posted April 20, 2019 Share Posted April 20, 2019 The biggest issue with the MMC slot on the CC2 is the fact that it isn't secured very well at all. Seems it was just press fit into place and the very small pegs on the MMC shroud were to slot into the holes of the PCB on the sides. But the entire assembly doesn't have a way to accurately tell you that the card is inserted fully as it doesn't really click or anything. As a result, I'm assuming these two CC2s that I recently worked on both had the shroud come off while trying to plug the MMC into it and not being sure it was fully seated. As a result using a bit too much force will cause the shroud to come completely off the pins and into the cart. That is for a fact what happened with one of them as told to me by its owner. In PMPs case I'm not exactly sure what happened, but I could see something similar happening and the shroud in the process of coming loose, could easily break one of the small ICs off the board that are situated in front of the shroud. PMPs was the NZ17 Schmitt trigger IC that controls the IO from the MMC to the FPGA from what I could gather in examining it? If a standard SD slot reader could be used, that would be more ideal but I'm not sure how it would logistically attach since it would have to see too low on the PCB and wouldn't physically fit. I supposed it might be possible to use some sort of small PCB that could attach to the pads on the main PCB where the current MMC pins are soldered to, and extend those contacts further up. Then attach the SD reader to the new contact pads that would be further up on the small PCB? I can't design it as I'm like Antonio Salieri here with Mozart as the true genius. I can recognize the genius and play....not compose. 1 Quote Link to comment Share on other sites More sharing options...
PacManPlus Posted April 20, 2019 Author Share Posted April 20, 2019 (edited) Thanks guys... Short of having an adapter, my idea was to permanently add a micro sd slot (as the MMC cards get harder to find)... Like this: https://www.mouser.com/ProductDetail/SparkFun/DEV-13743?qs=WyAARYrbSna7AKzdOk0X8g%3D%3D&gclid=Cj0KCQjwhuvlBRCeARIsAM720HqmOgZYddEyheFZbyUHUM1I3k6jAXjY_mK_cwEZaK07iP2KZmV2WuUaAkxYEALw_wcB or this: https://www.newark.com/molex/503398-1892/connector-micro-sd-8pos/dp/09X1353?gclid=Cj0KCQjwhuvlBRCeARIsAM720Ho1Bd3akCBZgOwka6I1ckNomwaj46KJVw6xGNaQ69wnMGJFWBLYxSkaAkffEALw_wcB&gross_price=true&mckv=slDMAkpdW_dc|pcrid|81515568741|plid||kword||match||slid||product|09X1353|pgrid|20376566901|ptaid|pla-325659265361|&CAWELAID=120185550002947588&CAGPSPN=pla&CAAGID=20376566901&CMP=KNC-GUSA-GEN-SHOPPING&CATCI=pla-325659265361 I can then remove the original shroud and solder directly to the lines (something I would have to try without making any permanent connections first, obviously, as I do NOT want to damage this cart again) Glue the slot to the board where the original one was, and just use that from now on.

+Mitch Posted April 20, 2019 Share Posted April 20, 2019 Why don't you just glue the current Mmc slot down. I did that with one of my cc2s. Yes, you will still need to find an Mmc card. Mitch Quote Link to comment Share on other sites More sharing options...

Mitch Mitch that is exactly what I did once I repaired the traces to it and was able to get the tiny IO buffer IC back in the circuit again. But even glueing it down, I could see the shroud still coming off again in time. There is actually a of the PCB that is a large ground plane. Might be possible to install a standard SD slot on the back side of the board and wire it to the pads for the MMC portion on the front side. Then scrape away some solder mask and solder the outer shield of the SD reader onto the exposed ground plane in several places to hold it down firm. There might even be room on the back side of the PCB to do this, but it would mean that my IC breakout board repair I did on his cart would have to be relocated elsewhere.

PacManPlus Posted April 20, 2019 Author Share Posted April 20, 2019 If I were to do this, I would remove the shroud (and give it to someone who needed it, as those are hard to come by) and have the micro sd slot *take the place of* the MMC slot. It would get glued in place: The idea was to desolder the pins, and glue this micro SD slot in place, and solder the pins to the correct hole: But looking at it now, I don't think there's enough real estate... so this all may be moot. I guess I'll just try to find more MMC cards. Anyway, thanks guys Quote Link to comment Share on other sites More sharing options...
