hi, i'm trying to make USB_FS work on my custom board. my desired configuration is peripheral (otg can be ok, i have jumper on id: PA_10)i already have 2 USB HS so i can use only USB_FS mapped on PA_11 and PA_12 as OTG. i follow the st wiki at the po...
I'm using a custom board (it is not DK1 even tho it says on boot log) with STM32MP157AAC. The boot hangs on u-boot without proper error message. Where should I start to search the failure? NOTICE: CPU: STM32MP157AAC Rev.Z NOTICE: Model: STMicroelec...
I have a custom STM32MP157c board. I try to set fuse bits (3 0x23000000). It worked on the basic boot system but not on the TF-A boot system. I mean by example the boot command : fuse prog 0 3 0x23000000.
Hi!I am using a STM32MP157C-DK2 board to create an application on the screen. I have used STM32CubeIDE to create my own program:I have initialized peripheral with its default modeI have enabled FDCAN peripheralI have changed the clock settings.With t...
Hello all!We have implemented our custom driver that uses DMA to copy a large amount of data from the FMC interface (FPGA mapped to it) to the RAM.For very fast data acquisition the setup time for new DMA transactions becomes critical.I tried an ov...
Hello community,we have the problem, that we need more code space for the M4 application and try now to get code area in SRAM2 (IPC area). What we've done so far:Decreased the number of vring buffers to the half: #define VRING_NUM_BUFFS 8 /* number o...
In my current project, I am still using the older environment. Even though there are no urgencies to migrate to the newer environment, I want to prepare everything in advance.My current project uses an external module to generate a signature. it work...

Hello, I am trying to establish an interprocessor communication between the cores A7 and M4 with the with the Stm32MP157. The example from ST "OpenAMP_TTY_echo" works fine, but as soon as I change the received buffer or try to send a costomize buffer...
