We have built a SBC using the 257EV as a reference in Altium. We are trying to use debug. We have created a ST14 connector to connect to a STLink3 using UART 2 as the debug serial port.Is this possible, and should we use SWD or JTAG to debug the proc...
Hi there,I am currently working on upgrading our EV charging solution from OpenSTLinux Ecosystem v4 (Linux kernel 5.15) to Ecosystem v6 (Linux kernel 6.6).As part of the process to ensure we are on the right track, I have successfully upgraded to the...
When trying to attach to M4 upon Linux boot (autoboot=1), it fails to bind resources:Remoteproc driver attempts to probe m4 resources, but all are waiting for pinctrl@50002000 which does not appear before remoteproc probe has timed out. I can see in ...
Hi Team We are looking for Processor or Controller which supports EtherCAT G and SPIAwaiting Your Reply ..
I am working with the STM32MP1 and using the STM32MP1 Ecosystem v6.0.0, Developer Package. have successfully enabled and configured the tamper detection feature using OP-TEE and the device tree. The tamper detection works as expected when the device ...
Hi,In Vbat mode (No Vdd), is it possible to pull up the tamper pins and detect tamper in High-Level.We did it in run mode. We enabled the pullups on the tamper pins which are connected to a detect switch. We detect tamper and erase backup registers w...
Hello,We are trying to run Tamper block in VBat (Vsw) mode. When we powered off the device, Vbat pin consumes 3 - 5uA from the battery as specified in device user manual.As we understood from the documentation, the source of Vsw domain (either Vbat o...
Hello everybody,i use "meta-st-x-linux-qt" with "meta-qt6" on STM32MP157https://github.com/STMicroelectronics/meta-st-x-linux-qtwhen I use "QMediaPlayer" to play an audio file it gives me the following error: could not load multimedia backend "ffmpe...
I am developing a new board and would like to know if the STPMIC25 is recommended over the STPMIC1 as a PMIC for STM32MP157 MPU.Which one should I choose?Thanks.
While reviewing the schematic of the STM32MP157 EVAL development board, I came up with the following questions:I apologize in advance if the translation isn’t perfectly accurate as I used a translator.The Line Out JACK (CN4) outputs via coupling capa...
