Boot on Latest Discovery429-DISC1 gets Stuck #1

Open gligorov opened 6 years ago

gligorov commented 6 years ago

Thank you for the great setup and instructions. I was able to build it, using Ubuntu VM.

Since I work on Windows, I did this to flash the board:

st-flash.exe --reset write stm32f429i-disco.bin 0x08000000 st-flash.exe --reset write stm32f429-disco.dtb 0x08004000 st-flash.exe --reset write xipImage 0x08008000

Next I restart the board, and use the serial to view the boot sequence, and you can see the image where it gets stuck below:

linuxboot

Last line that is pending is [ 1.220000] [<0800b20f>] (show_stack) from [<0800b7e3>] (__invalid_entry+0x4b/0x4c)

linuxboot

Any hints on what I am missing or not? I am using the DISC1 - latest version of the discovery, and I see on your images you have the prior version, not sure if there are any differences?

Thanks.

Hello,

I have the same problem on STM32F769-disco board project. Do you solved this issue?

Thank you

Hello, I have the same problem with stm32f429I-disco I have tried to download latest buildroot (2018.05.x) and built with stm32f429_disco_defconfig It works, but without display

Hello , I am not able to flash the board. I have follow the steps which are in README file. I have performed bootstrap and build. I got this error on make flash command.

Hi, all I have the same issue with no screen. Yet, I tried to hook up the serial on either USART1 or USART3, but seeing no output from the terminal of the putty.

Have you all resolved your issues already ?

Thanks. Eric

Update: It turns out that I didn't have the driver of CP2012 installed correctly. USART1 works.

adenis78 commented 5 years ago

It works, but without display

Is it means works and display to tty with serial port , just does not display on board screen? tty connection is ok?

ericyuncheng commented 5 years ago

Yes, if you hook up a CP2012 to the USART1, and reset the board, you will see the Linux booting process up to the point shown by Zan. I am not good enough to figure out what's wrong with it...

adenis78 commented 5 years ago

After building with binutils2.28 (not 2.29 or newer) = it's ok (not at all, however, see tty screen link below).

link to "Revert "configs/stm32f429: force usage of binutils 2.28.x"

fixed as adenis78 said.

how to fix the issue that tty message is constantly repeated?

adenis78 commented 5 years ago

how to fix the issue that tty message is constantly repeated?

just have to do (both) : 1) comment strings (tty2...4) in file $YourBuildRootPath/buildroot/output/build/busybox-1.27.2/init/init.c as done below:

static void parse_inittab(void)
{
#if ENABLE_FEATURE_USE_INITTAB
char *token[4];
parser_t *parser = config_open2("/etc/inittab", fopen_for_read);

if (parser == NULL)
#endif
{
/* No inittab file - set up some default behavior */
/* Sysinit */
new_init_action(SYSINIT, INIT_SCRIPT, "");
/* Askfirst shell on tty1-4 */
new_init_action(ASKFIRST, bb_default_login_shell, "");
//TODO: VC_1 instead of ""? "" is console -> ctty problems -> angry users
/*new_init_action(ASKFIRST, bb_default_login_shell, VC_2);
new_init_action(ASKFIRST, bb_default_login_shell, VC_3);
new_init_action(ASKFIRST, bb_default_login_shell, VC_4);*/

2) change file $YourBuildRootPath/config/busybox to: CONFIG_FEATURE_USE_INITTAB=n

Then the problem should be gone.

fangyaodong commented 5 years ago

I have completed the following steps, but the same problem still appears. Is there anything I have missed?

  1. According to link to "Revert "configs/stm32f429: force usage of binutils 2.28.x" prompt,I change "buildroot/linux/Config.in" with 1 addition comment "Linux kernel may fail to boot with binutils >= 2.29" depends on BR2_ARM_CPU_ARMV7M depends on !BR2_BINUTILS_VERSION_2_28_X

    2.comment_ strings (tty2...4) in file $YourBuildRootPath/buildroot/output/build/busybox-
    1.27.2/init/init.c /new_init_action(ASKFIRST, bb_default_login_shell, VC_2); new_init_action(ASKFIRST, bb_default_login_shell, VC_3); new_init_action(ASKFIRST, bb_default_login_shell, VC_4);/

    3.change file $YourBuildRootPath/config/busybox to: CONFIG_FEATURE_USE_INITTAB=n

And I use DISC1 ,Through the ST-LINK Utility flash。

Thanks.

fangyaodong commented 5 years ago

Thank you for the great setup and instructions. I was able to build it, using Ubuntu VM.

Since I work on Windows, I did this to flash the board:

st-flash.exe --reset write stm32f429i-disco.bin 0x08000000 st-flash.exe --reset write stm32f429-disco.dtb 0x08004000 st-flash.exe --reset write xipImage 0x08008000

Next I restart the board, and use the serial to view the boot sequence, and you can see the image where it gets stuck below:

linuxboot

Last line that is pending is [ 1.220000] [<0800b20f>] (show_stack) from [<0800b7e3>] (__invalid_entry+0x4b/0x4c)

linuxboot

Any hints on what I am missing or not? I am using the DISC1 - latest version of the discovery, and I see on your images you have the prior version, not sure if there are any differences?

Thanks.

Zan

hello
I also use DISC1 board,Are you running normally?

slaskhas commented 5 years ago

I had some success doing the following.

I was able to boot without (__invalid_entry+0x4b/0x4c) using recent binutils, by manually applying the following patch to arch/arm/include/asm/assembler.h ;

I ending up with the endless can't open /dev/tty2: No such device or address can't open /dev/tty3: No such device or address can't open /dev/tty4: No such device or address

but after applying the patch by https://github.com/adenis78 above , I get the prompt. No gui though.

lu1kaifeng commented 4 years ago

why no display on disco1 is it a driver problem or because of the board differences?

rodrigo455 commented 3 years ago

hmmm I can't tell exactly what is happening, but in order to get higher verbosity I recommend you to port this patch to the 4.15.7 kernel. It is from the emcraft's fork of the linux tree and it tells you more info about the exception.

ALTracer commented 2 years ago

@rodrigo455 Thanks for the assembly patch, it helped me boot this Buildroot on a stm32f429-disco board. The space constraints are too strict though -- I could barely fit inside the 2MiB Flash while tweaking configs of buildroot, busybox and linux kernel; enabling SPI, LTDC, disabling USB, stripping the DTB etc.

Here's my boot log, note it may be different from builds of clean checkout and default configs:

@gligorov Consider closing once you confirm the patch resolves your booting issue. To everyone else: I couldn't get the display to work after backporting DTS patches as there seems to be no panel driver for it. The README.md picture was taken from previous uCLinux builds, apparently. You should rather try fresh mainline kernel builds (5.15, 5.17) for any hope of working display.

how to tweak configs ?
can you share the tweaking steps and the final output of hex file ?

@rodrigo455 Thanks for the assembly patch, it helped me boot this Buildroot on a stm32f429-disco board. The space constraints are too strict though -- I could barely fit inside the 2MiB Flash while tweaking configs of buildroot, busybox and linux kernel; enabling SPI, LTDC, disabling USB, stripping the DTB etc.

Here's my boot log, note it may be different from builds of clean checkout and default configs:
