I guess, it has something to do with the secure monitor inited by TF-A, since GPIOZ is protected. Maybe there is something wrong with the default device tree using the GPIOZ? What can I do?
I've run a simple graphical program with Mono and OpenTK. It contains a simple fragment shader (demo). One frame renders about 7 seconds and CPU usage is 100%. Is it normal?vec2 p = ( gl_FragCoord.xy / resolution.xy ) - 0.5; float sx = (amp)*1.9 * si...
Hello ST communityI am having trouble configuring the Ethernet PHY on my custom board using the stm32mp153aac. The MPU is supposed to generate a 50 MHz reference clock for the transceiver, but when I measure the pin with the oscilloscope I get nothin...
When I run my M4 Application every thing is working fine. But while the Board boots until i start the M4 remoteproc the pin is on high level. How can I set the pins reset(boot) configuration to low? I'am using the developer package.
Hi, I need to save a variable from u-boot console but is not possible because the command SAVEENV is disabled (STM32MP1 module) . How can I do?
Hello,i use STM32mpu1-dk2 and want to implement an update over the air mechanism. For that i would duplicate all partitions from fsbl to u-boot, that meansfsbl, teeh, teed, teep, u-boot.Now i would like to know how one can tell TF-A which partion sho...
Hello, I received the STM32MP1 discovery kit and I started to use it.I installed SDK and I compiled successfully some hello world applications.Now, I would like to build some extra libraries to add, or in the future I may want to rebuild existing one...
Looking at this code:https://github.com/ARM-software/arm-trusted-firmware/tree/af1ac83e0fa4e77aad13e1e8e47b6fcafeb17dbc/drivers/st/mmcI don't understand if the methods are named after the sdmmc2 bus of the MPU (#1 for sd card, #2 for emmc) or it's ju...
Hi there,I am trying to get the ID of the MP1 from a given address. But when I try to do so in Linux, using the microprocessor core A7, it gives me a Segmentation fault (core dumped) error.When I run the same program on the microcontroller, core M4, ...
