Hello all,I am facing a strange issue where the kernel sometimes fails to reboot the system. Here is what I am seeing.I use busybox reboot -f from the command line so that the reboot request goes directly to the kernel, i.e. no init/systemd involved....

Hello there,We are working on a design based on the STM32MP1 eval kit which is using Realtek RTL8211 for Ethernet.However this IC seems to be hard to buy; Realtek distributors are giving lead times of +1 year.Can someone recommend alternatives?Thanks...

Hello, We are upgrading from BSP 2.1.0 to 3.0.0. With BSP 2.1.0 we had implemented a Secure Boot mechanism as described here, i.e. both TF-A and u-boot were signed with the STM32 Signing Tool and had a stm32 header added. Now with BSP 3.0.0 we se...

I am using GStreamer to stream live video from mjpeg cameras. For this I am using a pipeline which is roughly equivalent to this one:gst-launch-1.0 souphttpsrc is-live=true location=<camera_url> ! multipartdemux ! image/jpeg,framerate=0/1 ! jpegparse...

Previous kernel versions had support for the STM32MP1 internal temp sensor. See:stm32mp1-adc-temp definition in stm32mp157c device treeDT bindings documentationApparently this has been removed in later kernels. Isn't this supported anymore ?Thanks,Gu...

Thank you @Community member. We can now work around this by patching console_stm32_core_flush:Check UE bit in UART_CR1, if cleared, then do nothing - return immediatelyOn timeout, return immediately instead of calling plat_panic_handlerThis is teste...

Hello,Thank you for your answer.We are not using systemd -- we are using busybox init instead.However the setup is similar: if we use reboot instead of reboot -f, the init (pid 1) process is signalled, which then stops services, kills any remaining p...

Additionally, if your kernel has this patch applied:https://lore.kernel.org/all/20220602162119.3393857-7-ckeepax@opensource.cirrus.com/This is wrong and breaks the volume range for the "PGA Volume" control. The following patch reverts this:https://lo...

This is actually a bug that was introduced in the upstream kernel, in commit 4f1e50d6a9cf9c1b8c859d449b5031cacfa8404e ("ASoC: ops: Reject out of bounds values in snd_soc_put_volsw_sx()"). The problem is described in this thread: https://lore.kernel.o...
