Embedded Buildroot and Yocto Linux crash 50% of the time

Asked 2020-Nov-04 at 18:22

I am getting the below error 50% of the time during startup on an STM32 based processor (OSD32MP15x).

I've tried over 40 versions configs and setups none work and I am under high pressure to deliver this piece of hardware to a client. To me this looks like some kind of timing issue because it doesn't always happen.

I've tried to disable USB related configs, change DTS files and strip out everything that is not needed and last but not least change power config in the linux config and DTS.

Questions: How can I debug the below? What does this error look like to you?

ANSWER

Answered 2020-Nov-04 at 18:22

It looks like the problem was introduced by the patch: regulator: stpmic1: Usb boost over-current protection workaround.

The "boost" interrupt handler stpmic1_boost_irq_handler calls regulator_lock(usb_data->boost_rdev);
The "boost" interrupt handler (stpmic1_boost_irq_handler) is set up by the stpmic1_boost_register function, but usb_data->boost_rdev is still null at this time.
usb_data->boost_rdev is set to the return value of the stpmic1_boost_register function by thestpmic1_regulator_probe function.
If the "boost" interrupt handler stpmic1_boost_irq_handler gets called before usb_data->boost_rdev has been set by the stpmic1_regulator_probe function, then the crash occurs.

A workaround would be to set usb_data->boost_rdev = rdev; in the stpmic1_boost_register function after it has set rdev but before it sets up the interrupt handler.

This should be reported to the author of the patch. See the "Signed-off-by:" line in the patch for the email address.

Try adding the kernel command line option rootwait to bootargs so that the kernel does not immediately give-up and instead waits forever hoping the root filesystem appears. It might be that kernel did not wait long enough during boot-up for the SD card to appear.

ANSWER

Answered 2017-Dec-22 at 02:59

You must use props for pass data from parent component to child component.
You can use 'dot notation' for access to object properties. If you want to get access with bracket notation you should write string like obj['property']. Read property accessors

QUESTION

UBI layout volume not found

Asked 2019-Oct-13 at 18:00

I am following Bootlin's embedded Linux training which aims to put an embedded Linux system on an Atmel SAMA5D4 Xplained board (theory slides, practical lab instructions) and I am stuck a putting the whole system on the NAND flash.

They ask me to put the DTB, the kernel, the root filesystem and a data filesystem in a UBI image to be written to the flash but I cannot access the UBI partitions once I flashed it (the access fails with error code 22, or -22 in an embedded Linux environment).

Detailed description

In U-Boot, the partitions are defined by mtdparts:

ANSWER

Answered 2019-Apr-08 at 09:28

Thanks for the very well described problem and questions. It's a pleasure to help you in such conditions :)

There are a few things don't seem right, or which at least are not in the spirit of Bootlin's lab.

You don't have the mtdparts settings in the kernel command line. As a consequence, you're working with the default partitions.
You're flashing your UBI image into the 5th MTD partition (from the offset you're using) but are trying to attach UBI to the 6th partition. No surprise that you have UBI attach issues.
When erasing and flashing the UBI images, you should use partition names instead of offsets. This will clarify things and reduce the risks of errors.
You should group the dtb, kernel, rootfs and datafs partitions into a single MTD partition called "ubi", which you will use to flash the UBI image and then to attach UBI. So instead of MTD partitions, you will have 4 UBI volumes, as described by your ubinize configuration file.

This should definitely help. Don't hesitate to come back if you're still facing issues after doing this.

Happy hacking and learning

QUESTION

Async function stops processing and fails to throw exc only on production aws ec2 cluster

Asked 2019-Feb-04 at 04:31

I've run into an unexplainable error condition when I deploy the below code to my production site. Locally, all of these functions were tested and working.

I've tried gaining insight into the promises where it seems to fails, but they don't trip any exceptions. The usersApiGateway.getNonce is a get request and I verified that I get the correct return value when I send the get request on POSTMAN.

On my AWS logs it basically shows it executes up until the point designated below, and then just stops. And then after maybe 10 minutes it quits attempting to call the process via asyncTimeout and it then is permanently stuck. Any help on how I can find the root cause of this is appreciated.

ANSWER

Answered 2018-May-08 at 01:24

The failure to mount the rootfs is occurring because the correct partition of the SDcard has not been specified.
In the kernel command line, the kernel is (incorrectly) instructed to find the rootfs in the partition corresponding to /dev/mmcblk0p1.
