Resolved! Is it possible to use STM32MP157A-EV1 SOM in a custom MotherBoard?
Is It possible to separate the STM32MP157A-EV1 MPU Subsystem Daughterboard (MB1263) from the motherboard (MB1262) to integrate it into a Motherboard of our design? Are there any limitations for its use when not paired with MB1262?Thank you!
Cryptodev/af_alg engines in OpenSSL on STM32MP157C-DK2 do not provide hash algorithms for hardware acceleration
Hello,I have successfully compiled and deployed the distribution package (trusted) onto the STM32MP1. I am using OpenSSL in a program for signing data, where SHA256 is used as a hash. I would like to take advantage of hardware acceleration by using e...
Resolved! STM32MP157C-DK2 maximum current 5V/3V3 pins
Hi,I want to connect some shields/sensors to STM32MP157C-DK2. Some of the sensors will draw about 200mA. How much current can I draw from the 5V/3V3 pins on the GPIO expansion connectors? The STM32MP157C-DK2 is powered over USB-C 5V/3A. OpenSTLinux i...
Resolved! OpenAMP hangs at MX_OPENAMP_Init() when started from U-Boot, even after waited for linux to fully booted up.
When I run the openamp image through linux command prompt, the application working fine. The RPMSG devices is created successfully.But when I've tried to run it from uboot, it stuck at MX_OPENAMP_Init(). This should be ok because I assume linux isn't...
Resolved! TFA boot failed with emmc flash
Hi, I has two custom boards. There are have same stm32mp157 ic and ddr. The difference is emmc flash, A's from micron and B is THGBMNG5D1LBAIL. Basic chain:The A and B are bootup success.Trusted chain(TF-A + U-Boot)The A is bootup success.The B is bo...
First steps with STM32MP1
Hello everyone.I am introducing me on this world of multiprocessors, by the moment I only had worked with NUCLEO-F3 boards or similar.For my new research, I plan to purchase a SOM + Carrier board with the STM32MP157C microcontroller.My intention is t...
