Good afternoon, I have written two versions of the time output test programs to the console for STM32MP157D. Both programs work no more than 2 hours, then the system restarts. What did I do wrong?Sincerely, Alexander. ////////////////////////////////...
Hi,We are using stm32mp157a processor in my custom board.In my custom board we have limited peripherals so i need to disable remaining peripherals like ltdc and hdmi ,etc. I disabled in dts files but it didn't effected. How can i disable peripherals ...
On my Ubuntu 20.04, Flashing of STM32MP157C-DK2 with STMCubeProgrammer fails with the following error I easily reproduced using the scripts:$ STM32_Programmer.sh -c port=usb1 -w FlashLayout_sdcard_stm32mp157c-dk2-trusted.tsv -------------------...
I use a STM32MP157C and connected to MAX24287 PHY by RGMII.After linux booted there is only 100Mbps connection - I put the PHY into Diagnostic Loopback Mode and the situation is the same.My dts:ðernet0{ pinctrl-names = "default", "sleep"; pinctrl-...
How can I configure the i2c duty cycle to 50% in the linux device tree for a 33kHz device?I have modified the frequency from 100000 to 33000 but I couldn't find a setting for the duty cycle and right now I measure ~83%.MPU stm32mp153.
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...
We are trying to bring-up our custom board and every step of the way we see panic messages, we need some direction in understanding what went wrong. Our board has the following:Processor: STM32MP157FACxQSPI NAND flash memory is our boot device (AS5F1...
From my understanding of the documentation, my steps to lowest power (VBAT mode) on the STM32MP1-DK2 kit would be: Connect Battery to VBATSet BREN in TF-ADisable wake sources other than from PMIC and RTCenter sleep via: "echo mem > /sys/power/state"I...
