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...
STM32MP157 SII9022 I2C always busy
I used the i2c4 for sii9022 chip,but it always busy and don't response for hdmi plug in.
We see dull colours on our LCD, using "modetest" on our custom board, while the colours are bright when the same LCD hangs on the DK2. Are there possible causes we could check? Colour space, gamma correction?
We have made a custom board with an STM32MP157CAD MPU, this board is very similar to the DK2. We have adapted an LCD driver to support our LCD screen, over the DSI interface. It works, both on the DK2 with our own LCD screen, and on our custom board ...
Getting Started with MIPI DSI Display
Hello,I am fairly new to Linux and am trying to drive a DSI display using the STM32MP15-DK2 (not the one that came with the board) and was looking for some direction. I have been reading through the documentation related to DSI such as the DSI Intern...
Does STM32MP1 support double framebuffer ?
Hi Support Team,Please help me to get the answers for below questions.1) Does STM32MP1 support double framebuffer ?2) If it supports then how can we allocate memories for two framebuffer ?3) If not then how can we avoid tearing effects using one fram...
