Difficulties to boot on eMMC after update

Renesas RZ
1

Hi,
I am working on a BSP for a client who made a modified hummingboard for his needs, with a RZ/G2LC SOM on it.
We want to boot on the eMMC.

The board did boot ok on the eMMC in the past.
We worked from the commit 61338f8f “Update build process (kernel, initrd, flashwriter)”, Jul 13 2023.
No specific patch was needed in order to boot.

We want to update as you provided a few fixes and features since then.
Now I try to use the commit f22483f5 “tfa: optimise ddr parameter selection for size”, May 26 2024.
We try without modifying this commit, appart from changing the OS from buildroot to debian in the runme.sh script.

The image generation works. I also performed the uboot flashing as per your procedure:
https://solidrun.atlassian.net/wiki/spaces/developer/pages/476741633/HummingBoard+RZ+family+Boot+options#Flashing-bootloaders-over-serial

I am able to boot from USB drive as the README instructs :

sudo dd if=images/rzxxxx_solidrun_buildroot-sd-xxxxxxx.img of=/dev/sdX bs=1M

setenv bootargs 'rw rootwait earlycon root=/dev/sda2'
usb start
load usb 0:1 $kernel_addr_r boot/Image
load usb 0:1 $fdt_addr_r boot/rzxxx-hummingboard.dtb
setenv sdio_select emmc
booti $kernel_addr_r - $fdt_addr_r

But once booted, I cannot find any /dev/mmcblk0 device.

I also tried to boot on USB drive with an old version, and flash the new image on the eMMC.
What I understand is that u-boot starts. It decompresses the kernel and loads the devicetree OK.
Then the kernel starts but when looking for the rootfs, it can’t find the /dev/mmcblk0p2 partition.
So is it the Kernel misconfiguring something so it looses the eMMC ?

I include the boot log from this attempt below.

Here is what I checked:

  • The uboot is ok loading the kernel from eMMC
  • Uboot has the gpio to boot on eMMC : board_select_sd_emmc: select emmc.
  • Also it doesn’t modify the devicetree for uSD support patching DTS | keep default settings
  • linux devicetree is in eMMC mode rzg2lc-hummingboard.dts:17 #define SW_SD0_DEV_SEL 1

I am a bit blocked here and wonder if I could have missed something.

Any help will be appreciated,
Bax

Recently we are finding some boards having an issue with the timing on the vqmmc regulator for switching the sdio lines between 1.8V and 3.3V. We are narrowing down the issue and will post patches today.

3

We found an error in the renesas sdhi driver in regards to their voltage_switch function. It was just by sheer luck that the driver was doing anything correct at all, and was most likely they they aren’t supporting UHS modes for the uSDHC slot and only the eMMC, by forcing the default pin config for uSDHC to 3.3V and for eMMC 1.8V (even though it was only supposed to be for UHS modes).

I have a complete patchset I am working on to simplify and make this work correctly but requires the attached patch, device-tree changes, and a u-boot update to handle some dynamic device-tree fixups.

You can test your eMMC boot by using the attached patch, and removing the vqmmc-supply and pinctrl-0 nodes for the sdhi0 node in your device-tree. We will finish our testing tomorrow and should push the full set of changes.

Hi @jnettlet ,
Thank you very much for your prompt reaction, I will try this today and keep you updated.

Hello again,
I tested your patch, but it crashed a bit. I tried to boot on USB with your patch active to see if the mmc would show.

I removed the vqmmc-supply and pinctrl-0 nodes in the sdhi0, in files rz2lc-som.dtsi and rz_2l-sr-som-common.dtsi (see enclosed patch.
I boot with:

setenv sdio_select emmc
setenv bootargs 'rw rootwait earlycon root=/dev/sda2'
run usb_boot

The kernel panics when trying to initialise the eMMC driver:

[ 2.320474] pinctrl_select_state+0x0/0x30
