Ima li za linux neki softver koji može da pristupi registrima SD kartice i setuje ili obriše lozinku?

To je stvar koja je bila sasvim normalna na Nokia telefonima, a tu prostu stvar ne mogu da nađem nigde više.

SD Card Write protection

It is relatively unknown that SD/MMC cards also have an electronic write protection system.
Every card has two programmable flags, one for temporary write protection and
one to lock the card forever. Writing these flags is not supported by most SD host devices.
To remedy this, this page presents a program that allows a Linux host to configure the protection register.
...
Note that you must be able to access the MMC device directly. Some SD card readers connect over USB and export a Mass
Storage Device (ex. /dev/sda), which cannot be used. My Dell Vostro 1310 laptop shows the card to the operating system as
a MMC device. Most embedded boards, such as the Raspberry Pi, do the same. Therefore, I have compiled a static binary
that you can use on your Raspberry Pi and most other Linux based ARM embedded systems.
You can download it here.


Problem sa ovim je što radi samo na Malini (raspberry), a kada sam kompajlirao na laptopu (koji ima pravi čitač /dev/mmc... za razliku od usb čitača koji se javljaju kao /dev/sd...), dobijam grešku: RCA nnot found. Make sure /sys/ is mounted. Run this program only on the main volume, eg. /dev/mmcblk0

Lepo bih ja to koristio na Malini i ne bih se drndao sa laptop verzijom da ne postoji jedan malecni problem na Malini: Ona se podiže sa SD kartice, i jedina kartica koju mogu da zaključam/otključam je upravo ona sa koje se Malina podigla. A meni treba da zaključavam/otključavam neke druge SD kartice.

Help?

Evo na starom ARM6 androidu

Citat:


[+] Found RCA for /dev/block/mmcblk0: E624.
Error 25
[-] Failed to send command: Not a tty



Karticu je gađao, i odgovorila je

/sys/bus/mmc/devices/mmc0:e624

Mrzelo me da čitam izvorni kod.
