Below follows results of the tests, using the 20150716-r285616 RPI-B image (built last night, propagating now). For completeness, I've included 'mmcinfo' output from u-boot, but what is really interesting is cards (7) and (8). To make sure the test was run with a working card, I tested the BeagleBone Black image on card (7) which booted fine. 1) FAILED PNY class 4 SDHC 8GB U-Boot> mmcinfo Device: bcm2835_sdhci Manufacturer ID: 2 OEM: 544d Name: SA08G=20 Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: Yes Capacity: 7.2 GiB Bus Width: 4-bit =20 2) SUCCESS Sandisk (Ultra) class 10 SDHC (I) 8GB U-Boot> mmcinfo Device: bcm2835_sdhci Manufacturer ID: 3 OEM: 5344 Name: SL08G=20 Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: Yes Capacity: 7.4 GiB Bus Width: 4-bit =20 3) FAILED Kingston class 4 SDHC 8GB U-Boot> mmcinfo Device: bcm2835_sdhci Manufacturer ID: 2 OEM: 544d Name: SD08G=20 Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: Yes Capacity: 7.4 GiB Bus Width: 4-bit =20 4) FAILED Kingston class 4 SDHC 8GB U-Boot> mmcinfo Device: bcm2835_sdhci Manufacturer ID: 2 OEM: 544d Name: SA08G=20 Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: Yes Capacity: 7.2 GiB Bus Width: 4-bit =20 5) SUCCESS Samsung (class unknown) SD 2GB U-Boot> mmcinfo Device: bcm2835_sdhci Manufacturer ID: 1b OEM: 534d Name: 00000=20 Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: No Capacity: 1.9 GiB Bus Width: 4-bit =20 6) SUCCESS Sandisk class 4 SDHC (I) 8GB U-Boot> mmcinfo Device: bcm2835_sdhci Manufacturer ID: 3 OEM: 5344 Name: SS08G=20 Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: Yes Capacity: 7.4 GiB Bus Width: 4-bit =20 7) FAILED Kingston class 4 SDHC 4GB U-Boot> mmcinfo Device: bcm2835_sdhci Manufacturer ID: 2 OEM: 544d Name: SA04G=20 Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: Yes Capacity: 3.6 GiB Bus Width: 4-bit 8) SUCCESS Kingston class 4 SDHC 4GB U-Boot> mmcinfo Device: bcm2835_sdhci Manufacturer ID: 2 OEM: 544d Name: SA04G=20 Tran Speed: 50000000 Rd Block Len: 512 SD version 2.0 High Capacity: Yes Capacity: 3.6 GiB Bus Width: 4-bit Glen --wRokNccIwvMzawGl Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJVp8kfAAoJEAMUWKVHj+KT8u8P/RkMs+0vTLmRpc9ccofR/ItF CZXnYTogcOjg9X2lkIl5RnS9uM6e9wDuZ1mo+nOEYY7/T6tjR8W6eWVTCFVqabv0 rNXFbCqmGi3zh8RfsBBjV5+EcP93rFww6KrLDKCvJ23/QNgxDiI7cit2Cu3VBj3a dVmxfLKanHBOVyh6/S+H8YOGRFVQBQFKvdZ3kQf54gNvDExnR2orf8zDbafPBGZU D27Hb9Bx2xdPS4wRZ9xdCeKmLb9g34nEkQwKyPNs3uU+IIdmrAwquN3nQkxExlqI iac0ATfS9zm5PqhaPAYWa2bBRA6uauMM+MhJYte/4K+bvzqUn5jxUZ9R1wIiTwqe w+aV4FNmWJK+1Z7STcoAAEIlmnLYOvokJXT9U9+fYohkT1SOVu9JsWCiK1HZdHV+ 1sOR0X+4qgtiQxiUSd/uxwin8z9vVw8DciimhMxk0DoSKsIWvHkMK3jXqML6QyYG Yvx9rphh0s0lNMe5lFtWgTjxPKgsQyJDVelXxlPKjOO7f5PDmw60tNhH298IZtfk aF5du79XEHU4R9E7x7JgHMGzQWKwr2w0TKUVZLtOrxzoymVGZP+ea9123rI2hbXt CidjyjMsfZBy6bJylN9bjbZKKox26/DxxbziqeR/yMDrHEFkDGrujcp6GkEnnvw6 wIEGkLFmD2bwC9dNiABc =AhJr -----END PGP SIGNATURE----- --wRokNccIwvMzawGl--
