I just saw this. It's from STM32MP157 discovery board.Notice that DQ9 is attached to E3.This schematic is the RAM DDR memory: They are connected correctly. The index of DQU2 is the 10:th index of DQ, also DQ10. But the naming of the net labels seems ...
I'm going to build my own computer by using STM32MP157 and install OpenSTLinux onto it. The powering for STM32MP157 can be done via USB-C connection, but that requires an USB-C charger of 5 volts.Can I skip that and only using a regular charger like ...
Hey, I'm following the Distribution Package tutorial, specifically the QT image and SDK with EGLFS tutorial: wiki I did build the Qt image with bitbake st-example-image-qt but building the SDK with bitbake st-example-image-qt -c populate...
Hello! I'm trying to figure out if the M4 has the ability to put the A7 to sleep but haven't quite figured out how to get the info from the M4 to the A7 at this time. I've been going through the forums and the Ecosystem V5 page and haven't had much...
I realize this is probably a pretty basic question but I haven't found a way to have the M4 portion of the firmware startup when the STM32MP1 is powered up. I'm currently using an STM32MP157D-DK1 board, if that helps. I was able to debug the code of...
With reference to RM0436, the STM32MP157 Reference Manual, revision 6.On pages 1066 and 1072 the schematic structures of a GPIO port are drawn (figures 119, 120, and 122). These all show an inverter circle on the gate of P-MOS output transistor and n...
I know this is probably a really stupid/noob question but I was trying to flash the STM32MP157D-DK1 board I have for the first time following the following guide:https://wiki.st.com/stm32mpu/wiki/STM32MP15_Discovery_kits_-_Starter_Package I ran into ...
Hello,We are designing a custom board with the "STM32MP157FAC1" MPU.Would it be possible to get the die to BGA package pin delays for the DDR3 and the EMMC interfaces ?The AN5122 seems to only have track lengths. Our PCB track layout has some constra...
As in a different post, The TF-A build did not create the FIP binaries after deleting the FIP build folder.This article does not describe how to create a new FIP binary. only how to update. very confusing !The fiptool does provide a create function b...
When using the latest git to build TF-A . Have been following the README_HOW_TO form git. All the steps are given blow.1. The git does not contain the build file .sdk , it is only provided in the ECO package. it is not clearly stated to get the file ...
