Hi,I would like to read the timestamp value of the RTC. I see that only the Cortex A7 have access to it and the documentation on the wiki does not give any clue to how we can read the timestamp from the m4.On the linux side i can easily obtain it:I k...
Hello We are trying to implementing IPCC in STM32MP1-DK1 evolution kit and facing following issues. We generated cortex-M4 code in CUBE MX (Activate IPCC,NVIC IPCC RX1,IPCC TX1 and debug UART) then run in CUBE IDE and generating .bin file. We ...
Hello,I have rather a simple question. In my project, I have 16 discrete inputs. I need to test all but only if works or not. From a hardware engineer's point of view, it is sufficient. For the test, I try to use a simple console syntaxgpiomon --sile...
Hello.There is a problem flashing the system image to the board.I use MYD-YA157C-V3 board of Myir company. The board contains a 'MYC-YA157C' CPU, which is based on the STM32MP157 processor (STM32MP157AAC3).I mounted an SD card on this board and attem...
Hi!Our custom board sometimes halts instead of rebooting. Has anyone already seen something like this?Connect to device by terminal or ssh:$ rebootThe terminal then logs all shutdown messages, but sometimes (every third?)it stops with this:[ 4253.287...
On STM32MP1, how to use the internal temperature sensor, ADC2_INP12 and internal factory calibration?Any example?Is it possible to access these data via A7 or just on M4 ?
We have selected FC-12M 32.7680KA-A3 for our new project and we wre in proto 0 , as per datasheet & previous design , load capacitance selected as 11 pF ( 2 X 22 pF) but RTC init is failed in STM32.we tried multiple value and its init is successful a...
Hi all ~I'm using our custom board with STM32MP157c MPU. I'm almost done with everything, and finally I'm going to change the u-boot and kernel splash images.I referred to the link for changing the u-boot splash image and I think it's very simple.htt...
Hello,we (me and @Daniel Laszlo Sitzer ) and are working with a product based on the STM32MP157A and using TF-A, U-Boot (but not OPTEE).We are in the process for transitioning from TF-A v2.4 to v2.6 and are tryingto understand how we are supposed to...
Please can you specify camera module for my application and please suggest any camera module that i can use according to the below mentioned camera specifications1)Camera should be of 5MP/2MP.2)Camera interface should be of DCMI protocol.3)Camera sho...
