We use HSE osc instead of xtal as suggested by errata. However to support STANDBY we need to turn it off by GPIO. The idea is to boot from SPINAND on HSI and turn HSE in bootloader.Unfortunately it seems that ROM hangs when HSE is not present:< @ 006...
I have an STM32MP157 discovery kit and we are considering using STM32MP157 at my work for a future PCBA we are creating.We would like to connect an external UHS1 microSD slot to the STM32MP157, but for data collection writing at 100 MB/s. We would al...
Hello, I have done the modification in the device tree related to inclusion of usart3 as per 3.3.1 Activation of a USART or UART instance in https://wiki.st.com/stm32mpu/wiki/Serial_TTY_device_tree_configuration&usart3 { pinctrl-names = "default", "s...
Hi,I'm using a custom board with custom device tree, the distribution is built with ST's Distribution Package (st-image-core). Now the bootloader (u-boot v2020.01) freezes while "starting kernel" with some strange errors before. Should I search for e...
Using STM32CubeIDE Version: 1.6.0 on Linux I am able to follow the wiki to import, build, load and modify the OpenAMP_tty_echo application example. However, when I follow the same steps to import the FreeRTOS_ThreadCreation_CM4 application the progr...
Hello. I am working on standby/wakeup using gpio pin in stm32mp1 custom board. Going to sleep works well using gpio-keys but I can't wakeup. What bothers me most is that interrupt responsible for waking up does not set "waleup" attribute although it ...
I find the kernel Panic when I mmap 16 shared memory regions.（4KB/memory）
Whether it's to minimize computational power, improve the device's output or keep the GUI from freezing or crashing, debugging embedded software can be a challenging and time-consuming step in the process of developing embedded devices.With a multitu...
We've created a bunch of sample touch screen apps in our Storyboard ST GUI builder software that you can download, and save to your hardware. In moments, you'll be able to visualize and interact with a fully-functional sample touch screen application...
