Tool/software:

Hi experts,

After solving the previous issue with the serial console for the early stages of booting, I am now stuck
at what I believe is the point where the A72 is about to start the main U-Boot process.

Here is the boot log:

What worries me is the warning about not enough space for the FIT buffer:

alloc space exhausted
Could not get FIT buffer of 1118628 bytes
check CONFIG_SPL_SYS_MALLOC_SIZE

Could this be that the large u-boot FIT image does not fit and therefore cannot be started?

The U-Boot fit image (u-boot-asp3-hs-fs.img) looks like this:

# Enable SPL MALLOC SIZE
CONFIG_SPL=y
CONFIG_SPL_SYS_MALLOC=y
CONFIG_SPL_SYS_MALLOC_SIZE=0x200000
But if I do that, the board won't boot:

    Hello Bo,

    check CONFIG_SPL_SYS_MALLOC_SIZE

    We are past the R5 SPL stage so the above should not be impacting the U-Boot boot.

    Can you double check if the U-Boot alias for UART is also changed correctly like you did in the previous E2E for R5 SPL stage.

    Hi Keerthy,

    The alias is present in the A72 dts as well so that shouldn't be the issue. Do you have any other ideas?

    Regarding the "alloc space exhausted", the number indicated is always one byte larger than the tispl.bin:

    dfu-util:
    Download        [=========================] 100%      1118447 bytes

    Log:
    alloc space exhausted
    Could not get FIT buffer of 1118448 bytes

    I tried do debug but I am unsure if relocation has taken place or not. Either way debugging doesn't show any
    useful info, seemingly pointing to vsprintf.c

    Hi Bo,

    I will loop in the DFU expert to check if that is specific to DFU before that Is this also seen on other boot modes?
    Any other boot modes that are working fine?

    Hi Keerthy,

    The "alloc space exhausted" is solved. I copied and used the new defconfig files as a base for our own configs. It works fine now.

    The boot will still not go further than:

    Trying to boot from DFU
    ############DOWNLOAD ... OK
    Ctrl+C to exit ...
    Authentication passed
    Authentication passed

    Since the DFU process is where we program the serial nor I have not yet been able to try booting normally.

    I can make an effort in getting the boot files into flash (by booting 2023.04 first) and get back to you.

    Best regards,

    I don't know if it is any help but I have two additional observations:

    If I boot with 2023.04, the last two "Authentication passed" lines takes about 1 second each. In 2024.04 the are very quickly printed out.

    I can turn debug on in security.c (#define DEBUG at the top). That gives me some debug prints in the SPL stages, but not for the last two lines:

    Hi again,

    I could really use some help here.

    As I attach my debugger in the hanged state, if seems to be stuck at an "udf" instruction, which
    would immediately lead to an exception.

    TI__Guru**** 164950 points

    Hi Bo,

    Apologies for responding late. Can you check if the control is passed to U-Boot or this udf happens in A72 SPL?

    Hi Keerthy,

    Control is passed to U-Boot. I have used the 2024 three first boot files and then successfully booted a 2023 u-boot.img

    Something is wrong in the A72 U-Boot setup. I can't figure out what.

    /Bo

    TI__Guru**** 164950 points

    Hello Bo,

    Since this is happening so early at the boot, one thing is suspect is some over write of U-Boot image. Do you have a debugger to dump back and read the binary just before U-Boot execution?

    Since we are sure that U-Boot is hanging can you add an infinite loop at the starting of U-Boot and step through to see where it's crashing? Let me know if you want me to share the code where U-Boot starts execution.

    Best Regards,

    Keerthy

    Good suggestion. If you could, please let me know what to add and where.

    Hi Bo,

    I am actually out of office & not having access to my boards.

    Can you take a look at the diff below that adds an infinite while right at the beginning of the U-Boot:

    diff --git a/arch/arm/cpu/armv8/start.S b/arch/arm/cpu/armv8/start.S
index 6cc1d26e..40bf1dc2 100644

+       b loop
        /* Allow the board to save important registers */
        b       save_boot_params
 .globl save_boot_params_ret

    You should connect debugger & update PC to next and break the loop. Then step through & see where it crashes.

    Also check if the U-Boot contents are in tact.

    Hi Keerthy,

    I did this to make it stop only in the A72:

    #if !defined(CONFIG_SPL_BUILD)
    loop:
    b loop
    #endif

    I am stepping the U-Boot code and everything seems to be fine, it reads environmental variables etc etc. After 137 hits in the memset function in string.c, I can continue stepping but since I don't know where it hangs I could step forever. Continuing the run creates the hang, and when I ctrl-c all I see is a bunch of udf #0 at a certain address. See picture:

    All the zeros makes me wonder if this has something to do with reallocation? Do you know where the entry point for the reallocation process is so I can try to break there?

    Bo,

    Understood so this is not helping. Can you share the sizes of all the 3 boot binaries in the working older SDK vs non working latest SDK binaries?

    Best Regards,

    Keerthy 

  • 0 in reply to Keerthy J
    Intellectual 591 points

    Hi Keerthy,

    Here are the size differences:

    Older SDK:

    tiboot3.bin: 277664
    sysfw.itb: 269718
    tispl.bin: 1113703
    u-boot.img: 1425955

    Non-working binaries:

    tiboot3.bin: 284332
    sysfw.itb: 269718
    tispl.bin: 1130151
    u-boot.img: 1494759

    Stepping at the very en before hang shows that there is a problem with clocks, perhaps with the timers setup. We only use one timer, so that one has been enabled in our dts. I see that in the common-proc-board, there are no timers defined at all.

    Here is the debug just before hang. You see that register x4 is 0x0 and the code branches to the address that x4 contains:

    I have checked, double checked and triple checked all configs and dts:es against the evm versions. I can't find anything strange. Still it seems that the console uart (main_uart0) is not being setup properly, perhaps because of this clock issue.

    We only use one timer, so that one has been enabled in our dts. I see

    For now can we comment out the timer usage and can we check if we can run to U-Boot?

    Bo,

    Still not sure what's going wrong here. If you use the latest tiboot3.bin, tispl.bin and use older U-Boot.img does it work?

    Just want to isolate the changes in U-Boot that can cause the failure.

    Best Regards,

    Keerthy

    Yes, see above. Booting with latest tiboot3.bin and tispl.bin + an old 2023.04 uboot.img works.

    Hi Bo,

    Could you share the changes you have made on top of the SDK in the U-Boot folder?

    I want to review them. Have you ported all of the changes from 23.04 to current one?

    Hi Keerthy,

    I think I found the problem. There is something fishy with the new way the "tick-timer" is setup to &mcu_timer0 instead of the old way which declared a "timer1". Reverting to the old way of declaring it booted the U-Boot proper:

    U-Boot 2024.04-ti-g4bc0ca249954 (Apr 03 2025 - 14:45:26 +0000)

    SoC: J721E SR2.0 HS-FS
    Model: Schneider Electric AS-P-3
    DRAM: 2 GiB
    /drivers/clk/clk-uclass.c:112-clk_get_by_index_tail() prop: returning err=-2

    There still seems to be something wrong though. The above function is where I was ending up when debugging earlier.

    At least now it boots so I can go forward. If you have any more ideas please let me know, otherwise I'll mark this thread as resolved.

    Some additional debug prints will help. The above does not give much. Glad that you are booting to prompt.

    Hello Keerthy,

    I am "almost" finished with my changes to move to U-Boot 2024.04. I really want to align all my dts-files to the ones in the ti-branch.

    Leaving the "clk_get_by_index_tail()" problem for now, I want to focus on the tick-timer and setup of mcu_timer0 that doesn't seem to work for me. When I inspect the resulting dts for the common-proc-board it doesn't even contain the "tick-timer" property, so I wonder what I am missing.

    Do you have any more information about this change? I have seen indications that I might need to make sure that firewalls are being opened in the binman-files. Also, a commit by :

    "* Use mcu_timer0 defined in k3-j721e-mcu-wakeup.dtsi and remove
    timer0, we have its clocks set up in clk-data now"

    Can you point me to where this clock is set up?

    I have been able to get it booting by adding this in my u-boot.dtsi:

    &mcu_timer0 {
	status = "okay";
	/delete-property/ clocks;
	/delete-property/ power-domains;
	bootph-all;
};

    Maybe that can point you in some direction?

    Best regards,

    /Bo

    Hi Bo,

    The time part if we can revert to old dts then that should take care of the issue. Anything specific that you are looking for?

    I don't understand this sentence.

    I can't boot my board with the files produced from U-Boot 2024.04. The u-boot.img file makes the board hang. Here is a log:

... repeats forever

    With the debug on, I don't even get to the part where it waits for the u-boot.img file. It just repeats the last line forever.

    As I said above, if I add this to my k3-j721e-u-boot.dtsi:

    &mcu_timer0 {
	status = "okay";
	/delete-property/ clocks;
	/delete-property/ power-domains;
	bootph-all;
};

    the board boots, but there are clock errors that makes me suspect that the clocks are not setup properly. This is the boot log:

    Hi Keerthy,

    I think I found the culprit.

    We use U-Boot as a test framework in factory and therefore need to drive a clock pulse. For that
    reason we have added:

    CONFIG_TIMER=y

    in the U-Boot config, which makes the board not boot. Removing that config resolves the problem.

    If you have a workaround that would be great, since we really need to create that pulse using the timers framework.

    Best regards,

    /Bo

    Bo,

    This is something best checked with U-Boot list.
    u-boot@lists.denx.de

    We do not use the U-boot timer framework to create the pulse.

    Hi Keerthy,

    You don't have to create a pulse for the platform to hang. Just declare CONFIG_TIMER=y in U-Boot config. The platform won't boot.

    I have tried to load the U-Boot proper from the j721e-evm build with the config option turned on and that won't boot either. It hangs
    after "Authentication passed". My guess is that the tick-timer is messed up.

    Could you try to set the config on your setup and see if you can reproduce it?

    Best regards,

    /Bo

    Hi,

    Please share the patch. I will try to reproduce on the EVM. Also any other dts changes that you did for timers.

    Hi Keerthy,

    You just need to define the config. No other changes for timers.

    Hi Bo,

    Apologies for the delayed response. I believe this will be as issue as the config is not defined by default. I will try reproducing and get back early next week.

    Hi Bo,

    Like we anticipated we see a hang after R5 SPL stage:

    U-Boot SPL 2024.04-ti-dirty (May 05 2025 - 15:40:26 +0530)
    SYSFW ABI: 4.0 (firmware rev 0x000a '10.1.6--v10.01.06 (Fiery Fox)')

    Since we do not enable CONFIG_TIMER by default we cannot catch this.

    Hi Keerthy,

    I understand that you can reproduce my problem.

    Is there any chance that you can support CONFIG_TIMER? We really need it to create
    an output pulse for an external chip. In my opinion it is a config option that is quite commonly
    used.

    If not, would it be a problem to go back to the old way of defining a timer of our own to be used
    for the "tick-timer" property instead of the mcu_timer0? Could you confirm that it would be
    ok to define the tick-timer that way?

    If the old way is possible then you could try that, Right now our internal U-Boot expert is out of office.
    I need time till next week to check if the CONFIG_TIMER is a possibility.

    /Bo,

    The team is busy with the next SDK release. No progress on this. I anticipate this will not be done in the next couple of weeks.
    This is a new requirement(Not part of the SDK) and prioritization has to be done.

    This is still not part of SDK. I want to check if this is needed as part of SDK? Or you are unblocked?

    Intellectual 591 points

    We are unblocked at the moment but I had to rewrite our whole pulse generation unit to not use DM_TIMER.

    For a long term solution we are very much in need of the TIMER framework to be functional in U-Boot. I find it strange that you introduced a change that broke it.

    Hello Bo,

    I have raised an internal requirement for this. This will be implemented in one of the next SDKs.

    Closing this thread as this is not part of the SDK yet.
