Hi! I am following the tutorial How to optimize the boot time for stm32mp157c-ev1 I have enabled FastMap but the time is not reduce (about 10s to attaching ubi) I want to avoid attaching ubi... Is it posible load kernel and device tree in nand using ...
Using the Distribution Package for STM32MP1 I'm able to access to the rootfs partition, example:my_postprocess_function() { cp -dr /home/osboxes/www ${IMAGE_ROOTFS}/opt/ chown -R daemon:daemon ${IMAGE_ROOTFS}/opt/www/ }But how to access to bootfs p...
Trying to build image using unmodified distribution package. Hardware crypto devices are enabled in config:root@stm32mp1:/etc# zcat /proc/config.gz | grep CONFIG_CRYPTO_DEV_STM32CONFIG_CRYPTO_DEV_STM32_CRC=yCONFIG_CRYPTO_DEV_STM32_HASH=yCONFIG_CRYPTO...
Hello,I use STM32MP157C-DK2 board with freeRTOS.I run my bord in engeneering mode with default freeRTOS parameters provided by cubeMXI create tree threads in my application but the last does not start.May be it is a memory space problem. So I try to ...
Hello,I wish use FreeRTOS with STM32MP157C. When I configure my bord on CubeMX a message pop up says I should configure SYS parameter with an others time source than sysTick. But if I configure TIM1 for example I cannot assign TIM1 in SYS section .ca...
I guess, it has something to do with the secure monitor inited by TF-A, since GPIOZ is protected. Maybe there is something wrong with the default device tree using the GPIOZ? What can I do?
I've run a simple graphical program with Mono and OpenTK. It contains a simple fragment shader (demo). One frame renders about 7 seconds and CPU usage is 100%. Is it normal?vec2 p = ( gl_FragCoord.xy / resolution.xy ) - 0.5; float sx = (amp)*1.9 * si...
Hello ST communityI am having trouble configuring the Ethernet PHY on my custom board using the stm32mp153aac. The MPU is supposed to generate a 50 MHz reference clock for the transceiver, but when I measure the pin with the oscilloscope I get nothin...
When I run my M4 Application every thing is working fine. But while the Board boots until i start the M4 remoteproc the pin is on high level. How can I set the pins reset(boot) configuration to low? I'am using the developer package.
Hi, I need to save a variable from u-boot console but is not possible because the command SAVEENV is disabled (STM32MP1 module) . How can I do?
