FlexSPI NAND Flash on LS1028ARDB is not accessible from u-boot and Linux.
The Flex SPI NOR flash on the LS1028ARDB is accessible.
Access by U-boot.
=> sf probe 0:0
SF: Detected mt35xu02g with page size 256 Bytes, erase size 128 KiB, total 256 MiB
=> sf probe 0:1
unrecognized JEDEC id bytes: ff, 2c, 35
Failed to initialize SPI flash at 0:1 (error -2)
The JEDEC ID matches the data sheet. (ff → Dummy, 2c → Micron Technology, 35 → Capacity)
The goals are:
- Store the Bootloader in FlexSPI NOR Flash. → completion.
- Mount the NAND flash as UBIFS.
- Store the kernel and root filesystem in FlexSPI NAND Flash.
Boot the kernel and root filesystem mounted the NAND flash as UBIFS from the FlexSPI NOR flash bootloader.
Could you tell me how to use NAND flash and how to mount with UBIFS ?
