Hello,

Before you mark this as duplicate, i have read the Can't find PMIC:PFUZE100 but it does not really contain a solution.

I have an SBC RSC-imx61.

This is my setup :

mkdir avalue_imx-4.1-krogoth cd avalue_imx-4.1-krogoth repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1-krogoth -m imx-4.1.15-2.0.0.xml repo sync

MACHINE=imx6dlsabresd source fsl-setup-release.sh -b build_imx6dl
bitbake fsl-image-qt5
sudo dd if=fsl-image-qt5.sdcard of=/dev/sdX bs=1M conv=fsync

pretty standard setup, this is the output from the serial console.

I first tried to solve this by disabling the PFUZE100 in the menuconfig but the errors are the same.

Now, I'm new to Yocto and not sure what to proper way to solve this issue would be?

My main ideas was to:

1. Downgrade to another u-boot version but I'm not sure how to do that

2. Try to manualy solve the problem with PMIC, again i have not been able to locate where the code for PMIC even is.

I have been stuck for a few days and i'm running out of ideas Smiley Sad

Best Regards,

Willie

Hi Willie

one can try uboot/linux from nxp repository

uboot-imx - i.MX U-Boot 

https://source.codeaurora.org/external/imx/linux-imx/tree/?h=imx_4.1.15_2.0.0_ga

and debug (if necessary) using Chapter 22 PF100 Regulator Driver attached Linux Manual.

Best regards
igor

Hello Igor,

Thank you for your reply.

I downloaded the repo and I'm sorry if these questions seem trivial

1. Where/how do i configure the kernel for my board? There was only an x64 option, there usually is an ARM>little endian option.

2. If I compile the u-boot/linux stand alone i assume i cannot use my sdcard image, can i create my own MFG-tool version somehow?

thanks again,

Willie
