Hi there, I'm developing on a STM32MP157 custom board. I'm trying to work with power modes, and I tried to import the OpenAMP_TTY_echo_wakeup example inside our M4 firmware. I already had the IPCC module set up and I use virtUart periperal without an...
Greetings,in the video STM32MP1 workshop - 9 OpenSTLinux BSP pin Muxing - STM32CubeMX lab after modifying the DK2_TIMER_A7 project in the mx cube directly open the project in workbench from generate code, open the file.On my pc this doesn't happen, t...
In stm32mp157, I need two partitions for FSBL, and it is working correctly, but I want to make TFA redundant meaning I should be able to update the second partition of FSBL and then shift it on the second partition on restart.I have made roofs redund...
I am having trouble how to setup the Linux system on the STM32MP1 so that I can use sftp to upload data gathered by the device to an external server.What happens is that once the connection is established it immediately closes again, so there is no t...
I found the pin of PG8 on the GPIO pin map on the board. So I connected to PG8 and GND to connect with oscilloscope.In the picture, the blue line is the oscilloscope's GND port.I connected the board and the oscilloscope like the picture above. And I ...
Our product has a STM23MP151D, no security features (signed stuff or fuses blown) and the same QSPI NOR as the EV1 board.We have run the microcontroller style DDR tester (STM32DDRFW-UTIL) which took a bit of bashing to run on the 151 but did show our...
Is possible to install ppp tools to connect internet using a GPRS modem ?We need pppd/chat and kernel support to get network interface, but I can't found them on OpenStLinux resources.
I am using DP83848 PHY RMII interface and 50MHz external oscillator and PA1 as ETH_RMII_REF_CLCK pin. I ignored 125MHz input pin.But when active ethernet, I see a problem similar to Stm32mp157 Ethernet problem, saying that there is no input clock.I c...
