USB smart card reader, I suppose? Like I said, the USB-to-whatever bridge you're using has to support SMART protocol; there are even some USB-ATA bridges that fail to do so, so maybe the USB-SD/MMC bridge on BBB doesn't do that either. I only used high-level tools like skdump/smartctl---never wrote SMART-reading code like your example below. Does this code work on a standard x86 platform where, as you say, smartcll talks to your SD card? > I found a lot of subject on this topic, and I'm working on this piece of > code for the moment: > > int ret = 0; > struct mmc_ioc_cmd idata; > memset(&idata, 0, sizeof(idata)); > memset(ext_csd, 0, sizeof(__u8) * 512); > idata.write_flag = 0; > idata.opcode = MMC_SEND_EXT_CSD; > idata.arg = 0; > idata.flags = MMC_RSP_SPI_R1 | MMC_RSP_R1 | MMC_CMD_ADTC; > idata.blksz = 512; > idata.blocks = 1; > mmc_ioc_cmd_set_data(idata, ext_csd); > > But no result for the moment! > > > Le mar. 30 mai 2017 à 15:49, Przemek Klosowski < > przemek.klosow...@gmail.com> a écrit : > >> SMART protocol is defined for ATA interface, and it is translated over >> USB interface by most but not all USB-ATA bridges.
