Hi,<= /p>

 

As I wo= uld like to keep this issue alive, I am trying to raise it again.

&n= bsp;

QSPI dr= iver of u-boot-fslc seems to be broken for IMX6UL counter to u-boot-imx one.

Could t= hat issue be solved simply by replacing the QSPI driver by the one in u-boot-imx repo?

It work= s at least for iMX6UL EVK board.

Objet : [meta-freescale] [u-boot-fslc] QSPI driver

 

Hi all,

 

I am wo= rking on a project where all embedded linux components will fit in one QSPI= NOR flash (u-boot/kernel/rootfs). The board is currently the iMX6ULEVK.

 <= /span>

As I wo= uld like to boot a kernel that is in a UBIFS partition, I cannot use u-boot-imx version because mtd is not yet compatible with QSPI NOR f= lash unlike u-boot-fslc. The latter embeds that compatibility since 2015/= 07.

It had = been added through that commit:

https://github.com/Freescale/u-boot-fslc/commit/9fe6d871= 6e090f3b2dd3f4604acfced124b8a2fc

 <= /span>

Unfortu= nately, it looks like the qspi driver of u-boot-fslc is not compatible with iMX6UL. It is not able to probe t= he NOR flash (sf probe).

I had t= o replace the fsl-qspi driver with the one available in u-boot-imx and it w= orked then.

As both= fsl-qspi.c files are very different, I do not know how to add the s= upport of QSPI to iMX6UL in u-boot-fslc project.

I saw t= hat even the latest sources do not manage that hardware compatibility.

 <= /span>

Does an= ybody have an idea of how to solve this iMX6UL compatibility issue the righ= t way?
