In STM32MP1, there is an USB hub for 4 USB-A connectors. The hub is Microchip USB2514B. Were 4 means "4 ports".In STM32MP2, there is an USB too, for 2 USB-A connectors. The hub is Microchip USB2412B. Were 2 means "2 ports".According to AN5489, it say...
At STM32MP1, there is an USB OTG, were you can flash the eMMC via the USB OTG. But in STM32MP2, there is no USB OTG. Does this mean that I need to flash my SD-card instead? Just like Raspberry Pi etc.?Or am I supposed to flash the eMMC via the USB C ...
Hello,I'm considering basing a project on an STM32MP25x, and while it looks like a very capable chip I have some questions about the capabilities and their interactions. If anyone can point me in the right direction I will be very appreciative.First,...
Issue SummaryWhen trying to rotate the display on an STM32MP157C board from landscape (800x480) to portrait (480x800) mode, I'm experiencing issues. Using the /sys/class/graphics/fb0/rotate interface doesn't actually rotate the display, and using Qt'...
I understand this will have severely negative impact on performance. But can this be done anyway?If the answer is yes. A further question is, will this break the access to PCIE/NVME SSD for some hardware or software limitation, say, the driver or dma...
The DSI can be transformed to HDMI using the ADV7535BCBZ chip. My question is: Will I be able to see the boot screen at startup directly when the HDMI is plugged in and Linux is booting? Or must Linux start the DSI later after the booting process?Thi...
