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...
“Error: failed to download Segment[0]�?I looked at the other items with the same title but did not see an answer that would help me.I am using the STM32MP157F-DK2The demo code was working when box was openedI tried to run the demo“Populate the target...
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...
I am trying to use the USB OTG in host mode, but it kept giving me the famous HANG! Soft Reset timeout GRSTCTL_CSFTRST error.According to the datasheet, when we set the register, it should reset the core but also clear itself but the following condi...
I'm getting these errors on the consoles when FSBL (TF-A) is trying to download SSBL (U-Boot). What could this DFU error be? I've added the following to the U-Boot DTSI file so it ignore USB OTG VBUS and USB OTG ID. I've tried this using Linux and Wi...
Hi,I am wondering if it is possible to internally connect two GPIO pins by software, not using wires.Thank you
Hi!I am using STM32MP157C-DK2 board to create an application on the screen (using GTK library). My idea is to start coprocessor firmware from the A7 application with the following commands (system commands):int main (int argc, char **argv) { GtkApp...
I've been validating my DDR interface with DDRUTIL through the CubeMX DDR Interactive which seems to pass the tests. When I boot TF-A it is failing both address bus testing for 1's and 0's. But I can run this same test through DDRUTIL and it passes. ...
