SPI-NAND & 8-bit NAND flash
SP7350 supports ubifs (unsorted block image file-system) file-system as root file-system.
1K60 sector
Partitions, nand+_header, xboot1, uboot1, uboot2 and fip partitions , use 1K60 sector. 1024 bytes data plus 105 bytes parity comprise the sector and stored in standard 2k sector. It is able to correct 60 bits in 1024 bytes of data. It has higher ability for error correction than standard sector.
Standard 2k sector
Partitions, env, env_redund, dtb, kernel and rootfs partitions , use standard 2k sector. 2048 bytes data plus 64 bytes parity comprise the sector. Each 512 bytes has 16 bits parity and is able to correct 4 errors.
