Does SPL support the Nand Flash MTD driver and UBIFS file system

[adityanagal]

Hi ,

I am working over the IMX6solo based design. In this design , Raw Nand Flash is used to keep SPL, uboot and kernel .

I understand , MTD Nand Flash driver  and UBIFS file system. As per my understanding , when the SPL is loaded to SRAM , SPL should have the support of MTD Nand Flash Driver and UBIFS file system to load the u-boot from Nand Flash. My question is does the SPL supports the MTD Nand Flash driver and UBIFS file system. Please suggest.

Hello Aditya,

SPL mainly finishes Memory initialization / Stack settings / Flash initialization(NAND, EMMC, SATA,NOR etc), and loading code of stage 2 of u-boot into memory(SDRAM), So it shouldn't include device drivers and UBIFS.

Have a nice day!

Hi Wigros ,

If in my design , if SPL and uboot resides in the NAND flash  then how SPL would load the uboot from NAND  if SPL does not have the Nand Flash MTD driver and UBIFS file system. I believe both of these should be part of SPL and uboot. Please suggest.
