v851s can't start the Kernel

[voloviq]

Hello,

I have a small request and question about awboot and the Linux Kernel.

I compiled the awboot branch next and uploaded the code into Allwinner V851s Yuzuki board.

The awboot started well but the Linux Kernel won't start.

I use the official Linux Kernel 6.6.40 tarball with You patch. The Kernel compiled well. Maybe You have some idea what can be wrong. Can You also share Your defconfig for the Kernel, please?

Thanks for any advise. BR Michał

[szemzoa]

Hi,

Maybe you use another serial port, not the ttyS0? Try to add an early serial console to your bootargs on your proper uart, something like: earlyprintk=sunxi-uart,0x02500800 (for ttyS2, 0x02500000 for ttyS0)

linux-6.9.0.config.txt

[voloviq]

I modified You patch to uncomment and of course comment current records

+               stdout-path = "serial0:115200n8";
+/*             stdout-path = "serial2:115200n8"; */
+               bootargs = "mem=64M cma=4M root=/dev/mmcblk0p2 init=/sbin/init console=ttyS0,115200 earlyprintk=sunxi-uart,0x02500000 rootwait clk_ignore_unused";

but still kernel not start.

I will try later today recompile the Kernel with Your config. I let You know.

PS. I have a board with console on the UART0.

Thanks for now BR Michał

[voloviq]

Hi,

Unfortunately, nothing helps, nothing on the serial port and the Heartbeat LED doesn't work either. I also go back to fat partition instead of ext2 but also without success.

I believe there must be something in 'abwoot' branch 'next'. Did You check it on real hardware? There is something I need to change in 'awboot' code, maybe I forgot to define something?

Can You suggest me something ?

Thanks for any help. BR Michał

[szemzoa]

I can test it on the next week

[voloviq]

Perfect, thanks.

[szemzoa]

Hi,

I cloned the next branch straight from github, compiled, downloaded the latest kernel, patched (there are a few errors as I see, the ccu-v853.h is there twice, and the pwm isnt compiled, so I disabled that) and tried to boot from spi-nand and ext2fs, boot are OK.

spi-nand [1], ext2fs [2].

Many thanks,

The GCC compiler version I used may be wrong. I see in Your log that You use GCC 6.3 I used GCC 12. This may be an issue. I try the older version.

Once again many thanks.

BR Michal

[voloviq]

Unfortunately it isn't gcc problem. Maybe my compilation syntax is wrong.

make -j8 ARCH=arm CROSS_COMPILE=/home/mw/toolchains/gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabi/bin/arm-linux-gnueabi- LOADADDR=0x80008000 dtbs zImage modules

Can You please try my compiled zImage and dtb.

v851s-lizard.zip

[szemzoa]

v851-linux.zip

No, I compile the kernel like this: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j11

ps: This is a ext2/4 fs version on the first partition (mmcblk0p1), kernel and dtb on ext2fs in the /boot/ folder.

[voloviq]

Unfortunately, I can't break this topic.

Based on the awboot next branch plus my patch for Yocto I publicated the meta layer. If You have some time please compile a write to sd-card. At the present moment, I have no idea what can be wrong.

[voloviq]

Can You provide me a link to kernel You use during compilation?

PS. Do You have only one partition I mean zImage and dtb is located in /boot of main rootfs?

Thanks

[szemzoa]

I use the official latest 'vanilla' kernel from kernel.org, with the patches here for v851s, nothing fancy. I use the PE12/13 pins (uart2) for debug purposes, because I use usb-ethernet converter on USB, with alpine linux.

https://pastebin.com/TAbJzKwf

I have uploaded (a working for me TM:) compiled kernel and DTB, what should work for you too with unmodified awboot settings for yuzuki-lizard board. You seems to modified the bootargs for uart0 (console=ttyS0,115200). Did you tried the unmodified awboot with my compiled kernel and DTB on yuzuki-lizard board with a TTL-USB adapter connected to PE12/13?

Are we still talking about awboot here?

[voloviq]

Hi András ,

I resolved problem. The problem lie in hardware. I needed reduce CPU speed from 1.2GH to 0.9G. Now all of my kernels work well. In my opinion You get a better CPU which support 1.2GHz.

//xxx#define CONFIG_CPU_FREQ 1200000000
#define CONFIG_CPU_FREQ 900000000

I think issue can be closed.

[szemzoa]

Hi,

Great news, and good catch! I'll modify the default settings back to 900MHz, so others will not run into this problem. Glad to hear you have a working setup now!
