my stm32mp157f-dk2 board has a DSI (ECMF04-4HSWM10 filter) screen but my custom board is going to have a LVDS screen so what should I do different to protect the screen? (Filtering or ESD protection etc.)
I using a STM32MP-157F-EV1 eval board with linux Version 4.0.1-openstlinux-5.15-yocto-kirkstone-mp1-v22.06.15.CAN receive 500kBit/s fails, if I modify the sample point via an console command it works well. All other Bitrates 125kBit / 250kBit 1MBit a...
How can I remove QT5 from my build since there is a lot of dependencies and I am not going to be needing it. What is the best way to remove it?
Hi all ~I have STM32MP157C custom board. My custom board boot over eMMC. Occasionally, my board can not boot over eMMC with error message like below.Can I get some advice regarding this problem?Hardware of eMMC part is the same as EV1 board. Thank...
I'm having trouble finding documentation on how to access the upper OTPs by the unsecure world. I see that I have to manage exceptions by using STM32CubeMX but its not very clear on how to manage the exceptions using STM32CubeMX.
I've upgraded from 5.10 to 5.15 and can't make GPIO work anymoreI've tried thisgpio_keys { compatible = "gpio-keys"; input-name = "gpio-keys"; status = "okay"; halt { label = "Halt"; linux,code = <KEY_POWER>; // Key event to match wit...
Hi ST Team,We are working on product built around STM32MP157C. We are trying to generate the trusted image with Yocto. However, somehow the Trusted Firmware Arm (TF-A) is not getting generated. We have added following options in machine.conf file:BOO...
Is this processor capable to drive by parallel interface an RGB666 LCD display?What could I set in the device tree?
Hi,I have tried to migrate from ST Ecosystem 3.1 to 4.0.2 but I am unable to flash the image into the eMMC memory. My issue is similar to this one but I am using the Octavos SiP OSD32MP157c. As suggested by the original poster, the issue is probably...
In our custom board which uses STM32MP153C, right when TF-A is about to launch u-boot it displays PSCI power domain map logs and MPU reboots with MPSYSRST reason. Any idea what is the root cause? We are using the device tree based on the dk2 sample d...
