I couldn't find this in the official documentations. Does the BB OS support CPRM (Content Protection for Recordable Media)?
The reason I need this is because I want to put contents in SD card, which are not deleteable by users.
Usually, write protection is already supported by the SD card itself.
But it the BB OS doesn't have access to this feature, then I'm afraid that we, the application developer, cannot utilise this feature.

I also want to know whether these commands are supported by BB OS or not:
CMD55, ACMD44, ACMD43 GET_MKB, ACMD44 GET_MID, ACMD45 SET_CER_RN1, ACMD46 GET_CER_RN2, ACMD47 SET_CER_RES2, CMD48 GET_CER_RES1, ACMD18 SECURE_READ_MULTI_BLOCK,
ACMD25 SECURE_WRITE_MULTI_BLOCK, ACMD38 SECURE_ERASE, ACMD49 CHANGE_SECURE_AREA,
