![]() ![]() I wonder if anyone has a better way to deal with all replies than my current solution, which is to calculate the checksum from each of a few start offsets, until it’s correct. So there can be no hard rule to simply wait for 0xFE before reading in the reply (because it may never arrive, or may be part of the actual reply data). So I guess all the Thinkpad laptops with built-in SD card reader should work. update 1: Ive tried three more SD cards from different brand, all works update 2: I tried the app on my neighbors IBM X60, also worked. So an issue arises where the correct reply has to be aligned to calculate the reply checksum. Online SD card password calculator for VW, koda, Seat RNS315 navigation systems from CID number This device doesn’t change CID number and doesn’t extract unknown passwords from SD card. FYI the laptop is IBMs T61 with built-in SD card reader, product id is 7663MC2, the OS is Windows 7 32Bit Home Premium. (According to SD card specification the information is only to be. Something I’ve found interesting is that some cards send no 0xFE token before their reply, and some cards that do send the 0xFE token, also send an 0xFF byte before the token. The CID register is set when the card is manufactured and cannot be changed after it is set. For example, the serial number (PSN), date of manufacture (MDT) and also who actually produced the memory card is written in the unique CID or Card Identification Number. it’s easy to simply duplicate the CSD request routine, and change that to issue CMD10 instead of CMD9. What does CID mean Every SD memory card has internal registers in which important metadata about the card is stored. ![]() The CID register is set when the card is manufactured and cannot be changed after it is set. I suggest you make a note of the old CID first, in case you want to set it back later. One of these is the Card Identification (CID) Register, a 16 byte code that contains information that uniquely identifies the SD card, including the card serial number (PSN), manufacturer ID number (MID) and manufacture date (MDT). Hier gibt es die Möglichkeit sich eine (Abnahmemenge ab 20 St. Damit diese auch laufen, muss man sich einer SD-Karte mit änderbarer CID bedienen. I’ve since become interested in the SD card’s CID register, which is never accessed by MDDFS library at all, probably because the info contained it it is not vital to the card’s operation in the way the CSD register is. If you only need to change the card serial number (part of the CID) you can supply the old CID and the new serial number and the new CID will be calculated for you. Hallo allerseits, ich habe nun einiges an Suchen durchgeführt und musste feststellen, dass es für die Navis mit SD Karten nicht ganz einfach ist neue Karten zu benutzen. Hi Guys, When I was using Microchip’s MDDFS library in a project implementing an SD card, I filled in a few gaps such as retrieving the name of the partition, and card capacity, etc.
