I'm testing the Developer Package for STM32MP157c-dk2 demo board. Starter Pack is installed. When I compile the kernel as described in the Dev. Package's "README_HOW_TO.txt" file and update the kernel, The "Cube" example ceases running. It only says...
I want to enable input capture functionality on our stm32mp157c based system. I am using Timer 1 channel 4 for the same and have made the necessary additions in the device tree as follows: &dma1{ status = "okay"; /* USER CODE BEGIN dma1 */ s...
Hi everyone,I'm working on a custom STM32MP157 based board running custom Linux with Kernel v5.10.116. A LCD panel is connected using the LTDC display controller.I want to implement a splash-screen as soon as the power supply is on.I managed to add m...
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/ethernet/stmicro/stmmacCan anyone tell is this driver for some specific ST(?) IP, or for a runaway collection of various Synopsys based IPs? Does the ethernet control...
We are trying to read an analog value from a sensor (PF14 pin - A0 on Arduino connectors) and send it over UART (UART7 - PE7 for RX, PE8 for TX) for reading in the terminal of computer. We use M4 for this aim. Our final goal is to read the analog val...
Next problem with my board is the RS485. I can send bytes, but can't receive because after sending once the DE stays always high. Without sending receive of course works.&uart5 { status = "okay"; pinctrl-names = "default", "sleep","idle"; pi...
Hi i want to access remotely my stm32mp157c-dk2 with graphical interface. I am running openstlinux-20-02-19 from starter package. I installed tigervnc (apt-get install tigervnc and apt-get install xauth) and start it by typing "vncserver". But when i...
Hi, i am trying to build linux image along with cortex-m4 firmware which developed using STM32CubeIDE,so for that i have copied a Stm32CubeIDE project under folder DistributionPackage/openstlinux-5.10-dunfell-mp1-21-03-31/layers/sources/m4projects-st...
I have problem to get USB to work. I'm using custom board but I know that USB works because if I boot the board with the delivered image (MyIR) the USB works. I'm using buildroot with the 5.10 kernel and the linux kernel configuration from bootlin gi...
Hi I am working on a drivers for the various peripherals on the STM32. Let me take the GPIO as an example. GPIO BSRR is a write only register that I want to read and I need to read back always 0x00000000. Why?I made a bit-field struct on the whole GP...
