For measuring the USB signal quality, it is necessary to print out test pattern on the USB interface. How this can be done on a customer board with STM32MP15x controller. Is a test software or source code available?
Hi, I installed node.js with apt-get on my STM32MP157C-DK2, which worked great.Now I want to install another package but it failsapt-get install nodejs-npm... Need to get 7286 kB of archives. After this operation, 0 B of additional disk space will be...
What's the process to add a native gcc to openstlinux-weston so I can compile from the command line on my DK2 dev board? I was able to rebuild using bitbake and started poking around to find which layer to enable to get a native gcc running on the ST...
I'm following the OpenAMP_TTY_echo example.To do a Tx it basically uses two functions: VIRT_UART_Init and VIRT_UART_TransmitAfter I use VIRT_UART_Init, I can see in the Linux terminal a log message something that suggests the initialization is workin...

Hello. I am currently working on a custom stm32mp157a Linux based board with a KSZ9896 as network switch. At this point everything works on the board expect the RGMII connection to the switch. The RGMII is currently running in 100MBit mode for easier...
When booting off SPI NOR I would expect the device (an ST32MP151D) to possibly check the device ID then read a block starting from 0. Where is this fully documented ? What I actually see is two pairs of negative pulses on nCS then it floats open ci...
I'm working on a project using the Seeed Studio STM32MP157C-Odyssey-SoM (it is a module with the STM32MP1, DDR, eMMC and STPMIC). I am making a new PCB into which the module is plugged. When using the module on the original host board from Seeed, b...
