Hi,I am designing a product based on the STM32MP157DAC specifically using the TFBGA257 package due to its compact size. I was just looking at the datasheet (page 16, Table 1) and noticed that under the SDRAM section it seems that this package doesn't...
Hi,i have a question to the memory-controller and the supported memory-size.I'm using the Part STM32MP157CAAx (Package: LFBGA448).In the Datasheet (STM32MP157C/F) and AN5031 there is a definition to the supported SDRAM size.For package "LFBGA448" the...
Hello, I am working on bringing up the STM32MP257F-EV1 board and running into a problem with the steps on the page: https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP2_boards/STM32MP257x-EV1/Develop_on_Arm%C2%AE_Cortex%C2%AE-A35/Modify,_rebuil...
Hi,I am debugging STM32MP2 via JTAG and would like to access a process via DAP. I believe it is possible via the Debug Domain CID (DDCID)that is mentioned in this URL:https://wiki.st.com/stm32mpu/wiki/Resource_Isolation_Framework_overview Unfortunat...
Is there a tutorial for newbie? I made my custom board by myself as hobby.the board has switches to select boot 0 and boot 1, boot 2 is tied to ground through 10k resistor. so I could implement boot selector that switches between `00` flashing mode, ...
Hi,I am looking to design a board based on a 64-bit ARM processor, with interfaces including USB, Serial, and Ethernet. Could you kindly suggest any development boards that could serve as a good reference for this project?Your recommendations would b...
It seems that some of the ones my monitor is reporting ought to be within the range, but I'm only seeing Modeline 46:"1280x720" 60 74250 1280 1390 1430 1650 720 725 730 750 0x40 0x5 Whereas the following are rejected for various reasons - I can under...
Hello,I use SDL with X11 for now but I want to use it directly with kms/drm kernel driver. I run basic_splash_drm and it works.I don't know how to configure sdl to work together with kms/drm, somebody use it in this way ?Regards,Adrian
Currently, I'm running the M4 core by loading it through the A7 core.Is there any way to make these two cores start independently, without interfering with each other, and only perform communication?
I understand that there would be great performance penalty for the combination of cortex A35 core with octospi psram, but I want to know if this is possible after all? Of course, without great effort on modification of u-boot and kernel code. Just br...
