When compiling uboot, an error message is displayed when executing the script fiptool-stm32mp: create_st_fip_binary.sh: Command not found.I found the folder after decompression but did not find the file create_st_fip_binary. What is the reason?
Hey, I’m working with an STM32MP157D-DK1, I’m trying to trace for System Management Interrupts, to check how they affect the system.The following attempt was made to detect the latency of SMIs occurring on the system: # mount -t debugfs debugfs /sys/...
Hello,Based on 157DAC1-DK1, my board designed using 157DAA1. After I confirmed boot on DK1 board using image of sd card, I tryed boot on my board using sd card on same DK1 Image of sd card but failed. My board have only one I2C (I2C4) for PMIC. Can ...
Hello, I developed a custom board with a pinmap based on stm32mp157f - dk2.I think if you match the pinmap and use the start package, lcd and other features will work.I re-created the sd card according to that advice, and I also rebooted it, but the ...
Greeting.I'm trying to get our ADC subsystem up and running and getting weird errors in dmesg during boot. I'm assuming I've done something wrong with devicetree but I can't seem to figure out a working combination from the docs.Full part number of o...
I flash the image from FlashLayout_sdcard_stm32mp257f-ev1-ca35tdcid-ostl-m33-examples-optee.tsv pi@inspiron:~/yocto/build-openstlinuxweston-stm32mp2/tmp-glibc/deploy/images/stm32mp2$ STM32_Programmer_CLI -c port=usb1 -w flashlayout_st-image-weston/op...
Hi all,We are currently trying to add a QSPI device to the STM32MP135F-DK board. Using STM32CubeMX, we selected PB2, PF8, PF9, and PF10 as the QSPI pins and generated the Device Tree accordingly. We then built the image using openstlinux-6.1-yocto-mi...
I aim TO drive a mipi display screen on STM32MP257F-EV1, so I have to understand the DRM framework.After flash the new firmware, I found that the modetset always shows errors, so I want to confirm whether the support in this aspect is OK? But watchin...
Is it possible to use an STM32MP257F-EV1 miniPCIe with an external low-speed graphics card? I want to use it to run the PS2 emulator.
HelloI currently run on hardware STM32MP135f-DK and am preparing for running a custom HW.When assigning PA12 as a gpio-key in the devicetree,I get this error on boot:[ 3.544391] genirq: Flags mismatch irq 45. 00000083 (my-input) vs. 00002088 (0-0021)...
