imx8qxpmek: spi does not work on sd card boot

[heikoschocher]

Hi all,

I have an imx8qxpmek board developer kit and boot with sd card bootmode and the delivered sd card into U-Boot (or linux), and spi access works fine, see[1].

Now I builded the sd card image from the sources with:

$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-thud -m imx-4.19.35-1.0.0.xml

$ repo sync

$ DISTRO=fsl-imx-xwayland MACHINE=imx8qxpmek source fsl-setup-release.sh -b build-xwayland

[...]
$ bitbake fsl-image-qt5-validation-imx

and boot this image, but sf probe fails, see [2]. Building the spi image (with setting UBOOT_CONFIG = "fspi") from this source code and burning this image into SPI NOR (luckily this works with the original sd card) and booting the board with bootmode SPI results in working U-Boot with SPI NOR access [3]. Also linux boots and detect the SPI NOR now.

Ok, there are different U-Boot versions, also (and I think more important) other scfw firmware verions.

The U-Boot error log shows:

lsio_fspi0 [237] not owned by curr partition
sc_pm_set_resource_power_mode: resource:237 mode:3: res:4
Error: lsio_fspi0 Power up failed! (error = 243)

which means:

resource

#define SC_R_FSPI_0 237

and errorcode 4 = SC_ERR_NOACCESS

Ok, so I think I have to adapt the scfw ... but I am totally new to imx8 ... and I just wonder why with newer source SPI access does not work from sd card boot. Any reason for disabling this?

Remark: I downloaded the scfw porting kit:
https://www.nxp.com/webapp/Download?colCode=L4.19.35_1.1.0_SCFWKIT-1.2.7.1&appType=license&location=...

builded it and added the image successfully to the yocto build, but same result.

Any ideas, help, hint, where I have to tweak the source to get SPI NOR on sd card boot working again?

Thanks!

bye,

Heiko

I still has this problem (lsio_fspi0[237] not owned by the curr partition) when using Linux 5.10.9 version from building Yocto .

Can anyone help ?

Hi Heiko,

   Have you solved this problem?I'm having the same problem as you。

[heikoschocher]

Hi Hagen,

it seems to me it is a problem with scfw firmware ...

I added to "imx-scfw-porting-kit-1.2.7.1" the following 2 patches (Sorry do not know how to add here files)

HI Heiko,

   I tried your method is feasible.But I have a question.Same source code, I use Makefile to manually compile a flash.bin file to write into sd card, can use SPI flash.I suspect there is a problem with the yocto build.I tried to call SCFW's API in UBOOT to get the permission of SPI Flash, but it was not successful. Do you have any idea?Please tell me. Thank you very much..

Best regards
Hagen

[heikoschocher]

Hello Hagen,

Hmm... I am sorry, I cannot say very much, but a good lead. I did not thought about there could be a problem with SCFW API in U-Boot,as it is source from NXP. I just wait for the real hw from the customer, and if I got them, I can take a look again into it.

Thanks for the hint!

bye,

Heiko

[igorpadykov]

Hi Heiko

for "fspi0 [237] not owned by curr partition" error one can check
partition management discussion on SCFW Resource Management Confusion 

Partition APIs description can be found in SCFW documentation included in SCFW Porting Kit

The i.MX 8 and 8X families require a minimum SCFW release version for correct operation and

to prevent potential reliability issues. Versions compatibility can be found on

i.MX Software and Development Tools | NXP 

and described in  Linux 4.19.35_1.1.0 Documentation  (Release Notes)  

For example L4.19.35_1.1.0 should be used with SCFWKIT-1.2.7.1 and uboot v2019.04

uboot-imx - i.MX U-Boot 

It is not recommended to use SCFW release tied to a non-GA BSP release,

as early versions of the SCFW may lead to operational or reliability issues with the processor.

[heikoschocher]

Hello Igor,

thanks for your answer ... I use as base:

repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-thud -m imx-4.19.35-1.0.0.xml

So this should be correct, or?

And if building the image for the spi flash, and burning it, spi access works. But booting the sd card
image, SPI does not work (in u-boot and linux)

bye,

Heiko

[igorpadykov]

Hi Heiko

for building please use Yocto Guide included in Linux 4.19.35_1.1.0 Documentation

and Chapter 3 Porting U-Boot i.MX Porting Guide.
