That would not be a problem always working on the same type of cards. I use Arduino Uno to communicate with the SD card. I found couple of cheap SD cards that accepts CMD26. Hi all, I need to program the CID of SD cards. You also wrote that it's not just sending CMD26 on SPI mode and it's need to knock SD or MicroSD card into firmware mode, then once done, they do accept CMD26 and permanently accept new CID values. Using Arduino Networking, Protocols, and Devices. So please, explain exactly with what kind of cards you were able to do the job possibly specifying their manufacturer, brand, type CSD and original CID (in order to know their manufacturer date). I'm pretty sure I'd be able to do the job but unluckily I can't find the right SD/MMC. I don't know what do you mean about the different ways for different controllers you wrote, but in my opinion I think with the right cards isn't too hard to achieve the goal. You wrote that it is possible but very time consuming do the job since you will need to come up with different ways for different controllers and also creating something (Universal) that will work with every controller is almost impossible. Once you can reach the target with a certain type of cards produced by a specific manufacturer, then surely you can repeat the job on others cards which are the same as model, brand and manufacturer. So actually your answer has to be interpreted academically rather than like a possible solution to the problem, being in the facts that in real life the things are far from being as you have described them.Īnyway, you wrote that each controller needs different methods, I guess you mean working on different cards produced by different manufacturer's brands. (Even if I'm pretty sure that your statements are based on something like this old document here Not all computers with built-in card slots. This will not work through a USB card reader because the command to retrieve the card information is intercepted and not understood by card readers. Card readers in laptops are usually connected directly through the PCI bus (or IDE bus). I know I asked for a lot of informations and I hope you will answer. One way to read the CID is to use a laptop with an SD card slot. Knowing it would be possible to understand their manufacturer date and other useful parameters. You wrote 2 major manufacturers out of 4, but what exactly?Īn interesting thing would be if you could provide original CID and CSD of the cards that you have been able to change, is it possible?
