Looking at the u-boot driver (drivers/watchdog/stm32mp_wdt.c), it seems to hard code the prescaler to /256.There is no warning if the maximum timeout is set. The linux driver seems to handle values up to the maximum of 131 seconds. Is there some reas...
Hi there, I am working on a product where we use the STM32MP157C for our purposes At the moment we have the UART4 attached to A7. I wanted to move it to M4 so that I can start seeing the serial logs coming out of M4 rather than the A7 which is runnin...
As reported in the GitHub page, STM32PRGFW-UTIL should work with boards with USB DFU or UART serial interface.It works properly with UART, but it doesn't with USB DFU, showing the following error: Download in Progress: █████████████████████████████...
Hi,We are wondering that do we support to boot uboot from nand flash then boot into OS from external PCIE SSD driver.Is that workable to support this case by changing codes on stm32mp257 platform? Thanks.
Hello: I am debugging the network development of STM32MP135 bare metal, using the protocol stack LWIP+FreeRTOS, and I have implemented the LWIP transplantation of dual network ports under FreeRTOS, and can successfully PING the IP of the two network...
I'm testing STM32MP157A for our new projects. The MPU VCC is 1V8, USB is 3V3. Debugger is connected to two SWD pins. One of first test is:boot into DFU loader, upload simple code to 0x2ffc2500:S_GPIO_ALT(GPIOA,13,2); S_GPIO_ALT(GPIOA,14,2); RCC->MCO1...
HiI plan to interface the MT9M001 CMOS sensor (Parallel Interface) with STM32MP135F-DK, but the development board comes with the MIPI CSI2 Interface. Please guide me as to the process of integration and using OpenCv. Thanks
We are using STM32MP!57A processor in our custom board. In this we are unable to read the internal ADC values in our cards. Actually, we initialize the internal ADC pins in cortex-M4 core with support of STM32CUBEMX and debug in CubeIDE...
Hello everybody,I am developing a custom board strongly inspired by the STM32MP157D-DK1, except that I use a parallel DPI RGB on 24bit display.I use openstlinux-6.1-yocto-mickledore-mpu-v24.06.26.The frequency of "LTDC_CLK" changes by itself after wa...
Hi,I tried to update the DTS to make use of the adapter but unfortunately without success. These are the change I made:hdmi-out { compatible = "hdmi-connector"; type = "a"; port { hdmi_con: endpoint { remote-end...
