Hi, I'm using the Sina33 dev board and as the wiki page says, it has a 4GB eMMC (Toshiba THGBM5G5A1JBAIR). I'm trying to flash and boot a custom made debian based Linux image from the eMMC at the moment. I'm able to boot this image from the SD card, but no luck so far with booting from the eMMC.
What I did and got so far is trying to follow https://linux-sunxi.org/Bootable_SD_card and flash the eMMC while booted from the SD card: 1. *# mkfs.ext4 /dev/mmcblk1* *root@sina33:~# cat /proc/partitions major minor #blocks name 179 0 30183936 mmcblk0 179 1 8209408 mmcblk0p1 179 8 3866624 mmcblk1 179 24 2048 mmcblk1boot1 179 16 2048 mmcblk1boot0I don't understand why the boot partitions are not wiped.* 2. *# root@sina33:~# fdisk -l* *Disk /dev/mmcblk0: 28.8 GiB, 30908350464 bytes, 60367872 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisklabel type: dosDisk identifier: 0x6706f5d0Device Boot Start End Sectors Size Id Type/dev/mmcblk0p1 2048 16420863 16418816 7.8G 83 LinuxDisk /dev/mmcblk1: 3.7 GiB, 3959422976 bytes, 7733248 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk /dev/mmcblk1boot1: 2 MiB, 2097152 bytes, 4096 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk /dev/mmcblk1boot0: 2 MiB, 2097152 bytes, 4096 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytes* 3. *# dd if=sdcard-sina33.img of=/dev/mmcblk1 bs=1M* *( The SD-card bootable image)* 4.* # root@sina33:~# fdisk -l* *Disk /dev/mmcblk0: 28.8 GiB, 30908350464 bytes, 60367872 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisklabel type: dosDisk identifier: 0x6706f5d0Device Boot Start End Sectors Size Id Type/dev/mmcblk0p1 2048 16420863 16418816 7.8G 83 LinuxDisk /dev/mmcblk1: 3.7 GiB, 3959422976 bytes, 7733248 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisklabel type: dosDisk identifier: 0x6706f5d0Device Boot Start End Sectors Size Id Type/dev/mmcblk1p1 2048 4194303 4192256 2G 83 LinuxDisk /dev/mmcblk1boot1: 2 MiB, 2097152 bytes, 4096 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk /dev/mmcblk1boot0: 2 MiB, 2097152 bytes, 4096 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytes* 5.
