Hi, I have the Tiny210v2 SDK 1201 board. Both Linux and Android do not see any SD card. I've tried a few different cards. The hardware is OK, Superboot210 program FLASH correctly from SD card and Windows start correctly from card too. When Linux kernel boots (from FLASH or SD cards) it outputs: [ 1.497992] mmc0: new high speed SDHC card at address 0001 [ 1.513383] mmcblk0: mmc0:0001 L1BN2 7.73 GiB [ 1.525831] mmcblk0: response CRC error sending r/w cmd command, card status 0xb00 [ 1.537921] mmcblk0: error -84 sending status command, retrying [ 1.549407] mmcblk0: error -110 sending status command, retrying [ 1.560646] mmcblk0: response CRC error sending r/w cmd command, card status 0x800b00 [ 1.582148] mmcblk0: error -84 transferring data, sector 0, nr 8, cmd response 0x900, card status 0x0 .... Any ideas? Best regards, AWa.
Tiny210v2 SD card not working
I tried to slow down the SD clock and changed SD controller kernel settings without success. The test was made on 3.0.8-20130327 kernel. On kernel 2.6.35.7-20121027 SD card work without any problems. Best regards, AWa.
