Resolved! How to give execution permission to the M4 core for DDR RAM addresses?
I have a large firmware that the MCU must execute. It will not fit into SRAM1-4, so I am trying to move the entire code (or a portion of it) to DDR RAM. I have no problems reading and writing DDR memory from the MCU, as long as it's just data, but fo...
Resolved! How to make USB_FS work ???
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...
STM32MP157C U-Boot hangs after board information?
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...
How to set the OTP bits?
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.
Question about custom machine
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...
STM32MP157F: Dmaengine dmaengine_prep_dma_memcpy vs dmaengine_prep_dma_cyclic? Hardware vs Software triggered. (Linux)
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...
Decrease the size of the IPC buffer and put M4 code in this
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...
How to migrate from STM32IMAGE to FIP using Hardware Security Module?
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...
