SecureMMC card.

I would like to know if the SecureMMC can be used with the Himalaya. I realy need to use the secure features of this card.
Thank you.
Cesar Bremer Pinheiro.

I havent heard of that particular type of mmc, I think the "secure" part of "secure digital" refers to the little slider switch which when moved to the on position renders the memory card read only and so is secure from being overwritten.

Please see:
http://www.sdcard.org/sd_memorycard/index.html
This card isn't only a MMC card, it have secure encryption inside, suitable to protect data, the keys and encryption/decryption are inside the card. The device is a tampered resistant device, the keys will be erased if you try to open the card.

That site talks about SD (Secure Digitial) cards, which although are the same format as MMC cards, are not the same thing.
Both MMC cards and SD cards do work in the XDA and XDA2 though!

it's not called secure mmc it's called SD as in secure digital
it have the same packet as mmc and it's backward compatible with mmc
but there is where the similarities end they are very different internally
here is some reading
http://www.google.dk/search?q=mmc+vs.+sd&ie=UTF-8&hl=da&btnG=Google-søgning
and yes they work the xda both 1 and 2 dont have mmc slots they have SD slots which are backward compatible with mmc
how to take advantage of the encryption i dont know try googleing around for it

Universal re-partitioned your sd card from 4GB to 2GB? read this.

I've come across a little SD recovery app for 4GB cards that were partitioned for 2GB.
This is a transcend app, and they state its only for their X150 SD card, but i don't think there should be a problem recovering other cards.
I don't think there's any difference from other SDs.
(I haven't tried this cause i dont have a 4GB card, i just wanted to bring this to your attention...)
Try it out and report the results..

Good Luck!

micro sd

I've read that flashing with sd card it should be 2gb or smaller.
Would it be ok if I used a 4gb card and partitioned it in half so there were 2x2gb partitions?

4Gb SD card is SDHC compliant. Maybe update not work with old firmware on your mobile device. It`s safer to use old SD card less then 2Gb, because then is SD compliant (not SDHC).
SDHC cards require an SDHC capable device firmware.

When it says 2Gb or less it MEANS 2Gb or less.... No exceptions....

how to use sd card as emmc in i9300

i have faulty emmc i9300 so i remove EMMC and now new emmc is not avalable in my market so can i use a sd card as emmc and how can you send me a pinout of i9300 and sd card to use sd card as emmc
i found a topic on gsmforum (EMMC PINOUT)
but i not understande can you send a all pinout to use a sd card as emmc

You simply can't use ordinary sdcard in place of eMMC without modifying all bootloaders and kernel, as eMMC is using slightly different pinout (wider i/o bus for eg.) and a protocol.

Which driver is the built in MMC controller using?

I can't seem to get a vanilla kernel to detect the MMC cards (both the eMMC and the additional MMC card I inserted). Can we somehow find out which driver android uses for these?
