For one project we would want to use only de M4 core of the SM32MP157 MPU. We want this because we have no time to learn how to develop the whole application using linux and the whole potential of the MPU, but we would want to have the hardware ready...
If I order from st, how many days does it usually take to get to Korea?I placed an order last week... it's only for processing.
Hey.. Hi.. hello..Hope you all are doing wellI've my custom made board, which is quite similar with the STM32MP157 DK2 board Unfortunately, it's unable to bootDTS configuration for the PMIC, Clock and UART seems good I need to starts with the SPL/U-b...
Hi,iam trying to get a full understanding of remoteproc and its resource tabel. In the paper i read i understood it that the resource table is used to give the information about the vrings location to the master and the slave. The master parses the ...
Hi,I have been trying to flash the SD card of the STM32MP157A-DK1 following the instructions of the ST Wiki, although in this wiki the board used is the DK2. However the flashing process stops after a while and shows the errors that i attach in the p...
Hi,I am trying to debug in engineering mode with the STM32MP157A-DK1 through a external ST-Link V3 but i am not being able to get it to work. I attacht the error gotten, as well as pictures of the connection and the debug configuration in Cube IDE. ...
