I managed to make the M4 WWDOG to work.I got on Linux cmd line:remoteproc remoteproc0: crash detected in m4: type watchdogHow can I catch and handle this events programmatically on a shell script, C or Python ?
Please excuse my ignorance in this matter. We develop a custom board based on STM32MP15f-DK2. We would like to use Segger's J-link devices for initial codeloads.I understand that mmc/sd card are not memory-mapped flash types, so j-link will not work ...
we are using M28W320ECT 3V Supply Flash Memory for more than 10 years wo any problems in our MCU units now, suddenly in new production this part is gone defect several times- drawing current on the 12V programming Voltage Input, no read /write opera...
Hello,I am desing with reference STM32MP153 and I would like connect two devices to through of MAC to MAC ports without PHY layer, Is it possible?, In attach figure connection shonw as I should do the connection between devices without phy layer:Is i...
Hi,I am using stm32mp157c and fixed pll4p (125MHz) clock in dtb.st,pll@3 { reg = <3>; cfg = <3 124 5 5 5 PQR(1,0,0)>; };I see that pll4p is fixed (125MHZ )in clk_summury. But i want to change clock speed in run time if my condition become true. Se...
Any recommendations on how to install Node.js on OpenSTLinux / OpenEmbedded?I want to run some node.js applications on the A7 processor.I found this repository but there has been no activity for a few years.https://github.com/imyller/meta-nodejs
Hello!Board: STM32MP157F using STM32MP15-Ecosystem-v3.1.0We are using SPI4 to interface and control a FPGA by a custom SPI protocol driver.This works great!To get faster data transfer the QSPI interface should be used. The FPGA will deliver data with...
Hello,I've got problem with startup Display from Powertip. I added some commands to library ili9881c acording to datasheet by patch. After startup kernel [ 1.604819] [drm:dw_mipi_dsi_stm_probe] *ERROR* Unable to get peripheral clock: -517[ 1.724139] ...
Hi everyoneI am trying to modify the Kernel during the Distribution Package method (compiled from Yocto directly to the image)I have followed the information in the following pages:https://wiki.st.com/stm32mpu/wiki/WLAN_overviewhttps://wiki.st.com/st...
