Problem was solved by increasing the number of answer read attempts in mmc_= send_app_op_cond(). With attached patch (against latest driver version) car= d is recognized properly on ~ 190th attempt (while in original driver there= are only 100 attempts). Output from dmesg now: sdhci0-slot0: Card inserted mmc0: on sdhci0 sdhci0-slot0: Command error 1 (opcode 8 arg 426 flags 101 dlen 0 dflags 0) mmc_send_app_ocond(): cmd completed in 0 iter sdhci0-slot0: Command error 1 (opcode 8 arg 426 flags 101 dlen 0 dflags 0) mmc_send_app_ocond(): cmd completed in 195 iter mmcsd0: 1964MB at mmc0 50MHz/4bit GEOM_LABEL: Label for provider mmcsd0s1 is msdosfs/KODAK. Furthermore, non-mine SDHC card is now also recognized in this cardreader (= it doesn't even under Windows). In this case, it takes about 400 attempts t= o read answer. --=20 Ilya Bakulin --Multipart=_Sun__12_Oct_2008_17_12_01_+0400_e1mHiLotC0w.aU4r Content-Type: text/x-diff; name="mmc_c_inc_attempts.diff" Content-Disposition: attachment; filename="mmc_c_inc_attempts.diff" Content-Transfer-Encoding: quoted-printable --- mmc.c~ 2008-10-11 21:30:40.000000000 +0400 +++ mmc.c 2008-10-12 13:34:32.000000000 +0400 @@ -428,7 +428,7 @@ cmd.flags =3D MMC_RSP_R3 | MMC_CMD_BCR; cmd.data =3D NULL; =20 - for (i =3D 0; i < 100; i++) { + for (i =3D 0; i < 1000; i++) { err =3D mmc_wait_for_app_cmd(sc, 0, &cmd, CMD_RETRIES); if (err !=3D MMC_ERR_NONE) break; @@ -438,8 +438,9 @@ err =3D MMC_ERR_TIMEOUT; mmc_ms_delay(10); } + printf("mmc_send_app_ocond(): cmd completed in %d iter\n", i); if (rocr && err =3D=3D MMC_ERR_NONE) - *rocr =3D cmd.resp[0]; + *rocr =3D cmd.resp[0]; return (err); } =20 --Multipart=_Sun__12_Oct_2008_17_12_01_+0400_e1mHiLotC0w.aU4r-- --Signature=_Sun__12_Oct_2008_17_12_01_+0400_0_zhgMgXDi6X6+dB Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkjx96kACgkQo9vlj1oadwjF5gCgnVPkD6m95Cc+DsnlE934e7eL dSgAoNXvcx8U33ZXrTVrTlDqrqqynBUg =RaPu -----END PGP SIGNATURE----- --Signature=_Sun__12_Oct_2008_17_12_01_+0400_0_zhgMgXDi6X6+dB--
