DRA829V: Reboot command not working on J7 Linux

Part Number: DRA829V

Hi,

I was trying to execute reboot command on Linux A72 side.

It gets stuck and will not perform reboot.

Need inputs, what might be causing this behavior.

After executing reboot, attaching the end logs, we have waited for more than 30 minutes and system will not restart.

[ OK ] Reached target Shutdown.
[ OK ] Reached target Final Step.

Hi Rajendra,

I am using: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/latest/index_FDS.html

Log: https://pastebin.ubuntu.com/p/7spSQNGBfx/

You see that reboot works fine.

The latest is 7.0 Linux SDK. Couple of questions:

1) Which SDK version are you using?
2) Which boot mode are you using & can you paste the full log from u-boot to reboot failure?

Best Regards,
Keerthy

Hi,

we are using SDK 6.2.

Sorry, I will not be able to provide full logs from uboot till prompt, I am looking for Private E2E forum, once I received that I will add more detail logs there.

Rajendra,

I have the reboot working logs on the exact same 6.02 kernel:

https://pastebin.ubuntu.com/p/j67GjFckYq/

Can you just try to prepare card as suggested here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/latest/exports/docs/linux/Overview/PSDKLA_Formatting_SD_Card.html

Best Regards,
Keerthy

Hello Keerthy,

Ok. From the log you have shared, there is u-boot being triggered. Does this console log "reboot" you have shared, mean soc wide reboot or only A72 reboot? We require both and controlled.

For ex:

1. reboot -> can trigger A72 reboot while the rest of the R5Fs in Main and Mcu still active and running an TI RTOS instance

2. reboot -> can trigger an SoC wide reboot, asserting reset on all cores triggering a restart SoC wide.

Thanks,

Dev

Hi Dev,

Reboot from Linux resets the entire SoC and not just A72. If there are no further questions please
resolve.

Keerthy

Hi,

Can we know what happens when we execute reboot on Linux, which register is set, so that MCU will detect the register status and will perform the reset of SOC ?

Is there a way to perform reboot of only Linux, keeping other cores active ?

0 Keerthy J over 3 years ago in reply to Rajendra BK

TI__Guru*** 130430 points

Hi Rajendra,

I checked with the experts on this. Reboot command finally goes to the ATF. (Arm trusted firmware).

Sequence: machine_restart("arch/arm64/kernel/process.c") --> arm_pm_restart --> psci_sys_reset ("drivers/firmware/psci/psci.c")

This finally goes as a ATF call (Arm Trusted Firmware). So it is not a matter of reading a register from Linux or M3. ARM64 architecture
is implementing reboot via ATF.

To answer your second question to keep all the cores executing and only resetting A72 is currently not supported.

Hope this answers all your questions.

Best Regards,
Keerthy

Hi Keerthy,

thanks for your inputs.

We are using similar method to format the sdcard partition as mentioned in mksdboot.sh.

Still we are not able to see complete system reset, could you please have a look at below ticket, I have attached complete log, as requested above.

https://e2eprivate.ti.com/aptiv/aptiv_-_ep_automotive/f/infotainment-support-qna/15196/384-15196-j721e-dra829v-reboot-does-not-reset-the-linux-on-a72/87688#87688

Please let us know any other scripts or files needed or where to look at, to see, why system is not going for complete reset.

Thanks,

Rajendra

Hi Rajendra,

I am attaching the two files reboot.txt that successfully reboots at my 6.02 setup & reboot1.txt
which is your logs. I see bluetooth & wlan getting closed in your case which is not there in my setup.

Just to be doubly sure can you just try with just the dra829-evm with the freshly prepared card
from 6.02 sdk mksdboot.sh?

Are you using a custom board if yes then there might be differences that we need to look there as well.

You can compare the reboot1.txt & reboot.txt & see if you can get them removed to nail out
the blocking one.

Hi Keerthy,

We have tried OSPI boot made by keeping SPL & Uboot in OSPI and Kernel image and rootfs in SD card. Board is successfully booting up in fresh power cycle. when we tried reboot command, unlike earlier(SD boot mode) it getting rebooted but getting hard stop at Uboot level and printing below error

Card did not respond to voltage select!
Card did not respond to voltage select!
Bad Linux ARM64 Image magic!

Probably this might causing the reboot failure issue even in SD Boot Mode, so can you kindly let us know how to resolve this issue.

you can see the full logs in the attachment. Reboot-logs_ospimode.txt

Thanks,

Rakesh T

Hi Rakesh,

So this is different information. Earlier you were not seeing any u-boot prints in the second boot cycle right?

"[ 43.599120] systemd-shutdown[1]: All loop devices detached.
[ 43.616125] reboot: Restarting system"
I

It was getting stuck like mentioned above. just want to know how that was fixed in your side?

Best Regards,
Keerthy

Hi Keerthy,

Issue is still exist when we using SD boot mode. I mean upon executing the reboot command system is getting struck at reboot: Restarting system in SD boot mode(All bootable image in SD card) .

recently shared logs are with OSPI boot mode (SPL & Uboot binaries in OSPI and kernel and Rootfs in SD card).

Steps we followed:

1. copied SPL and Uboot images into OSPI and kernel&rootfs images into SD card.

2. sets BOOTMODE pins to OSPI mode and given a fresh power cycle

3. sets uboot env to load the kernel images from the SD card.

4. upon successfully loading kernel and getting login prompt run reboot command

5. reboot got executed and able to see initial logs in second boot cycle too, but getting stopped at loading kernel images from SD card by printing above mentioned error.

Thanks,

Rakesh T

Hi Rakesh,

RAKESH THOTTEMPUDI said:
3. sets uboot env to load the kernel images from the SD card.

After the above step all i did was for the first time i booted from SPI:

env default -a
saveenv
boot

Then i reached kernel prompt and entered 'reboot' command and i could boot to kernel
prompt. Tried this multiple times and it worked.

Best Regards,
Keerthy
