Hi Yang,

Please do the following experiment on your board:

Please run command 'devmem2 0x43010030 w 0x3b' before the reboot command. This switches to UART boot mode after reboot, then you would see a long character string printed after Linux is rebooted on the UART console on PC.

Do you see this string gets printed almost immediately right after the last line "systemd-shutdown[1]: Rebooting." message, or it also takes about 3~4 minutes to see it?

Hi Bin,

Our SDK version is 11.01.16, LPDDR4 capacity is 1GB, In the case of eMMC-only boot, we occasionally encounter an issue where the system gets stuck at the final stage of BL1 at asm("wfi"), during either a software reboot（reboot command） or a cold reboot（echo b > /proc/sysrq-trigger）.

I have updated the following files in arm-trusted-firmware:

The only purpose of these updates was to change certain INFO logs to ERROR level, in order to reduce interference from excessive INFO or NOTICE messages（Previously, I also inserted logs into the BL31 entry function (bl31_main. c void bl31_main (void)), but did not print the BL31 log information during exceptions）.

During reboot, the system occasionally shows the following abnormal behavior (the freeze always lasts exactly 6 minutes):

BL1 -> stuck for 6 minutes -> BL1 -> BL31

The following is the abnormal reboot log I captured today. It includes LPDDR initialization and training information, but when compared to the normal log, they appear identical.

Therefore, I would like to understand what the CPU is doing during this stable 6-minute period, so that we can reverse-engineer the root cause. For example:

Is it possible that BL1 is failing to locate the second-stage image (BL31) on the eMMC, and then iterating through other boot media (which might take about 6 minutes to complete a full cycle)?
Or is it waiting for DDR training to complete, with a DDR training timeout of 6 minutes?

In any case, this consistent 6-minute delay must correspond to a predictable internal process.

Hi Yufeng,

wei yufeng said:
Our SDK version is 11.01.16, LPDDR4 capacity is 1GB, In the case of eMMC-only boot,

How did you flash the u-boot binaries to eMMC? what is the boot mode pin setting on your custom board?

Hi Bin,

Thank you for your reply, I created an SD card boot disk and burned the complete system firmware (including u-boot image, kernel image, and file system image) to eMMC media using the 'dd' command.

My custom board boot mode pin[Bit0 - Bit15] is : 1100001100101100

The startup mode is RAW mode, and the u-boot offset relative to eMMC is 4MiB

U-boot packaging script:

dd if=/dev/zero         of=${U_BOOT_IMG} bs=1K count=8192 conv=notrunc iflag=fullblock && sync 
dd if=build/tiboot3.bin of=${U_BOOT_IMG} bs=1K seek=0     conv=notrunc iflag=fullblock && sync
dd if=build/tispl.bin   of=${U_BOOT_IMG} bs=1K seek=512   conv=notrunc iflag=fullblock && sync
dd if=build/u-boot.img  of=${U_BOOT_IMG} bs=1K seek=2560  conv=notrunc iflag=fullblock && sync

Hi Bin,

The environmental information is as follows:

The SDK version used is ti-sdk-11.01.16.13;

The ATF, Otee, and Ti Linux firmware used in the u-boot firmware are as follows:

~/ti-sdk-11.01.16.13/board-support/trusted-firmware-a-2.13+git

~/ti-sdk-11.01.16.13/board-support/optee-os-4.7.0+git

~/ti-sdk-11.01.16.13/board-support/prebuilt-images/am62lxx-evm/ti-sysfw

The cross compilation toolchain is as follows:

arm-gnu-toolchain-13.3.rel1-x86_64-aarch64-none-linux-gnu

arm-gnu-toolchain-13.3.rel1-x86_64-arm-none-linux-gnueabihf

The configuration file for uboot can be found in the attachment. config

The compilation script for uboot can be found in the attached build.sh file

The source code modification information for ATF, optere, and Ti Linux firmware is as follows:

ATF has been updated~/ ti-sdk-11.01.16.13/board-support/trusted-firmware-a-2.13+git/fdts/k3-am62l-ddr.dts, The purpose is to use the adapted DDR configuration information and change the DDR capacity in the memory node to 1GB (default 2GB)

optee, No changes made

ti-linux-firmware, No changes made

Abnormal phenomenon description:

The default ATF and optere log levels in uboot are set to NOTICE;

There is a probability (1/30) of getting stuck in the last ASM WFI of BL1 during repeated hot or cold restarts (echo b>/pc/sysrq trigger) until the 6-minute timeout, after which the CPU re executes BL1 and then starts normally;

Similar to CPU ->BL1->stuck for 6 minutes ->BL1->BL31->BL33->...

The following compressed file contains the compiled script:

I was asking what $U_BOOT_IMG is to understand where you flashed the U-Boot binaries to.

wei yufeng said:
and the u-boot offset relative to eMMC is 4MiB

I am not sure what it is, but

wei yufeng said:
My custom board boot mode pin[Bit0 - Bit15] is : 1100001100101100

It appears you use eMMC UDA boot mode.

Can you please switch to "eMMC Boot" mode (bootmode pin[3-6]: 1001) and flash the U-Boot binaries to eMMC boot0 partition to see if you still have such boot problem?

Hi,

The essence of $U_SOOT_IMG is an 8MiB uboot complete image, including (tiboot3.bin, tispl.bin, u-boot. img), packaged as follows:

dd if=/dev/zero of=${U_BOOT_IMG} bs=1K count=8192 conv=notrunc iflag=fullblock && sync

dd if=build/tiboot3.bin of=${U_BOOT_IMG} bs=1K seek=0 conv=notrunc iflag=fullblock && sync

dd if=build/tispl.bin of=${U_BOOT_IMG} bs=1K seek=512 conv=notrunc iflag=fullblock && sync

dd if=build/u-boot.img of=${U_BOOT_IMG} bs=1K seek=2560 conv=notrunc iflag=fullblock && sync

Yes, main boot mode is eMMC's UDA, and the offset of the uboot image relative to the UDA physical address is 4MiB

I will rebuild tiboot3.bin for booting on the eMMC boot0 partition. After actual testing, I will provide the latest results.

The device was set to "eMMC Boot" mode yesterday, with the operation steps as follows:

Step 1:

dd if=/dev/zero of=/dev/mmcblk0p3 bs=1M && sync

echo 0 > /sys/block/mmcblk0boot0/force_ro

mkdir /mnt/sdboot && mount /dev/mmcblk1p2 /mnt/sdboot && cd /mnt/sdboot

dd if=tiboot3.bin of=/dev/mmcblk0boot0 bs=1M && sync

dd if=tispl.bin of=/dev/mmcblk0boot0 bs=1M seek=1 && sync

dd if=u-boot.img of=/dev/mmcblk0boot0 bs=1M seek=3 && sync

The compressed file below contains："tiboot3.bin","tispl.bin" and "u-boot.img"

0310.boot.zip

Step 2：

mmc partconf 0 1 1 1

Step 3：

bootmode change to "emmc boot", boot mode pin[3-6]=1001;

However, after multiple soft reboots of the device (189 times this time), the issue of it freezing for 6 minutes still persists.

The logs for normal operation are as follows:

Hi Bin , sync a new piece of information.

1/In eMMC boot mode，Solder the pull-up resistors for eMMC lines D1-D7. After testing reboots over 1200 times, the issue was not reproduced.

（Two units were tested in total, both of which were devices that had previously been able to reproduce the issue..）

2/ Kallikuppa Sreenivasa He requested the removal of the pull-up resistors on D1-D7 and the pull-down capacitor on WAKEUP。

Retest Results:

①：In eMMC boot mode， Test 168 times，issue was reproducible..

②：After switching to eMMC UDA mode， Test 69 times， issue was reproducible..

Hi Yang,

For the eMMC D1..D7, the SOC is expected to enable the internal pulls after disabling the pulls internal to the eMMC device.

Can you verify if the internal pulls are being enabled?

Although optional, it is Ok to mount 49.9K or 47K pullups for D1..D7 since the parallel resistor combination will still be within the JEDEC spec in case SOC internal pulls are disabled.

Regards,

Sreenivasa

Hi Yang,

Can you please apply the following patch to TF-A (<sdk>/board-support/trusted-firmware-a-2.13+git), then rebuild U-Boot to see if it resolves the reboot issue?

Please test the patch without the external pullup resisters installed on D1..D7 when originally the issue happens.

Hi Bin,

Should sleep and log be added in the loop?

Hi Yufeng,

We don't have to. If the patch doesn't resolve the issue, the root cause is something else.

Hi Bin,

The pull-up resistors for D1-D7 are not populated.

Based on the above comments, the test results are as follows.

Hi Yang,

In the previous error log (abnormal_log.txt), the following message was printed the 2nd time at line 28, about 6 seconds after its previous line, and printed the 3rd time at line 42, about 6 minutes after its previous line.

NOTICE: bl1_plat_arch_setup arch setup

While with the patch, the console log shows the same message printed the 2nd time about 6 minutes after its previous line.

So basically with the patch the 6-seconds delay is removed, right?

I will try something on my evm and provide a debug patch next week.

Hi Bin,

I would like to consult another question.

As we are currently using eMMC UDA RAW bootup mode, tispl should be loaded to the 0x0 offset address of the eMMC UDA partition in this mode, but it conflicts with the GPT partition table; Based on our experience with the AM62X chip, we used a redundant address, which is the 0x400000 offset address of the eMMC UDA partition for load tispl. At present, this processing solution is running normally on our custom motherboard (except for the issue of being stuck in BL1 during restart).

Is this processing solution reliable, as the manual for the AM62L chip does support eMMC UDA RAW bootup mode.

Hi,Bin

We need to synchronize the test information.

1. We use "emmc+UDA+RAW" mode, the verification we performed yesterday based on your suggestions was also conducted in this mode,

Abnormal logs under this mode are consistent, without 6s repeated printing.

2.The 6-second repeated printing you observed was verified in the eMMC boot mode.

0 Bin Liu 9 months ago in reply to yang liu61

TI__Guru**** 180956 points

Hi Yang,

In general, the UDA RAW boot mode is not suitable for Linux, as you mentioned, the location of tiboot3.bin conflicts with the GPT table. So we don't recommend to use UDA RAW boot mode for Linux, regardless this 6-mins reboot issue.

The eMMC boot0 mode is resolved in AM62L SR1.1, so we should use boot0 mode from now on.

2.The 6-second repeated printing you observed was verified in the eMMC boot mode.

Does my "while(1)" patch make any difference in the eMMC boot0 mode?

Attached is the configuration of mmc0.

In SDK 11.01.16.13, the MMC0 devicetree pinmux in both U-Boot and kernel has been updated. Please see the details linked below.

Can you please update your MMC0 pinmux in both U-Boot and kernel to remove the pullup (_PULLUP) in MMC0_CMD and MMC0_DAT0, and test to see if the reboot stuck issue still happens?

Hi Bin，I'm sorry for the delay due to some unexpected matters.

The latest test results are as follows:

1.eMMC UDA RAW，added the patch and encountered a 6-minute freeze;

2.eMMC UDA FS，added the patch and encountered a 6-minute freeze;

3.emmc boot ，added the patch and encountered a 6-minute freeze; （the attached log is for this mode.）

You said you use SDK 11.1.16.13 and provided mmc0 pinmux back in Nov. 6, but your mmc0 pinmux doesn't match to the devicetree in SDK 11.1.16.13.

Can you please explain why they don't match? I just wanted to ensure you use the correct SDK.

Hi Bin,

As shown in the screenshot, we adapted the SDK 11.00.15.05 in August, and have already completed the hardware adaptation work for our custom board (dts device tree and GPIO pinmux); In October, we re adapted the SDK version 11.01.16.13 and reused the dts file from version 11.01.15.05 when adapting to this version of the SDK.

Hi Yufeng,

Which exact devicetree file(s) do you reuse from SDK 11.0.15.5? only k3-am62l3-evm.dts or some other *.dtsi as well? Please note that the SoC dtsi files, for example, k3-am62l-main.dtsi are quite different in both SDK versions, and they cannot be reused in new SDK.

0 wei yufeng 9 months ago in reply to Bin Liu

Hi Bin,

The following are dts and dtsi in u-boot, where k3-am62l3-pinmux.dtsi is for unified management of newly added files in pinmux, and k3-am62l3-evm.dts and k3-am62l3-u-boot. dtsi are the adapted device tree files.

u-boot-dts.zip

The following are dts and dtsi in kernel, where k3-am62l3-pinmux.dtsi is for unified management of newly added files in pinmux, and k3-am62l3-evm.dts are the adapted device tree files.

kernel-dts.zip

Except for dts or dtsi in the zip file, no other device tree files have been modified. Due to some reasons, I can only display a partial pinmux. If needed, I can provide it separately.

TI__Guru**** 180956 points

Hi Yufeng,

Can you please try to delete the following two lines form devicetree sdhci0 node in k3-am62l-main.dtsi in both U-Boot and kernel, to see if it has any impact on the 6-mins boot delay problem?

ti,otap-del-sel-mmc-hs = <0x0>;
ti,otap-del-sel-hs200 = <0x6>;

This change disables higher eMMC speed, and makes eMMC runs at the lowest speed.

Hi Bin,

We removed these two lines from the u-boot and kernel device trees, and the tests still froze for 6 minutes after restarting

The firmware now uses emmc boot0 and adds the "while (1)" patch

This is the kernel log before deletion:

Hi Bin,

According to your latest feedback, there is still an issue where it gets stuck for 6 minutes.（It occurs after 61 tests.）

Hi Yang,

I believe this is what happened:

The board has eMMC design problem which causes read issue sometimes. When the read issue happens in eMMC primary boot mode, ROM failed to load tispl.bin, then switched to the backup boot mode which is SDcard boot. Since the board doesn''t has a SD card inserted, it then switches back to eMMC primary boot and loads/runs tiboot3.bin again, but this time DDR init failed because DDR init has already been done when running tiboot3.bin at the first time. Then the boot process got stuck there for about 6 minutes until the watchdog kicks in and reset the entire AM62L.

The TF-A patch above was an attempt to solve the DDR re-init problem. But it seems the problem is not in the relevant code path. I am discussing the issue with our sw dev team to see if there is any solution for the DDR re-init, but the real fix has to in the eMMC design, I see our hw engineers have been discussing this offline.

Hi,Bin,

The PCB hardware for our V1.1 version has been received (the schematic has been revised according to the feedback from TI's hardware engineers).

We are use EMMC+UDA + FS mode, a total of 2 devices were tested.

1. When the U-Boot log displays these messages（see the attached figure below）, the 6-minute hang issue can typically be reproduced after approximately 100 execution cycles.

2. When the U-Boot log displays these messages（see the attached figure below）, it has been tested more than 3000 times and has not been reproduced yet.

I hope the information I provided proves helpful for your analysis. Thank you.

Hi Yang,

Thanks for the information.

I see the second log has more information than the first one, and the ATF/U-Boot have different build time. Do you use different build option or debug enabled in the second build?

I also see the ATF version is different in the two logs (v2.12.0(relase):V2.0.7-test.3 vs. v2.12.0(release):V2.0.0-beta.6). Why do you use the two different versions of ATF?

Could you please explain what you mean by execution cycle.

Hi Bin,

this is my fault. The provided image was only intended to demonstrate the difference in the amount of U-Boot printed logs.

The print log from the actual test can be seen in the attached image below.

Once the device starts up, execute the reboot command.
