I'm able with the PC to use the command smartctl to get info on my SDCard with the protocol SMART.
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!
