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!My Linux is booting on my custom board. This board is using 2 GB (16-bit density) instead of 4 GB (32-bit density).So, when Linux is booted. I get this.Can it be so CubeMX is only fixed to 4GB when selecting STM32MP257F? Any suggestions? The compl...
Dear all,We have a design where the VCCQ of eMMC is currently 3.3V. We need to move to 1.8V to be able to use a new referenceIs there any risk to break somthing if I use the below DTS on board where eMMC is 3.3V VCCQ. We have pull up to VCCQ on D0 an...
Hi!I have a STM32MP257F processor. The clock for SDMMC1 is constant at 3.3V. Therefore the U-boot cannot read the SD-card.My question is: What clock need to be active/chosed in the device tree so it u-boot can read the SD-card sdmmc1? Hit any key to ...
The project requirement is to use optical ethernet with STM32MP257F. I want to try this interfacing first at STM32MP257F EV1 with some copper to optical Ethernet converter module, but in STM32MP257F EV1, Ethernet pins are not available for interfacin...
Hello,I am following AN4803 to simulate my board with an STM32MP151 with DDR3L memory, but there seems to be a problem with the IBIS model. These IBIS models have missing receiver voltage thresholds, which may affect analysis:IBIS File: C:\Users\...\...
I am using the STM32MP131 in a baremetal environment. Since there is no internal flash, I am planning to use external flash and DDR.I have confirmed that writing to and reading from the flash works, but I don't know how to start from FLASH instead of...
Hi,I’m working with a MYIR MYD-YA157C (STM32MP157AAC) board and I’m trying to restore a board using STM32CubeProgrammer (USB / DFU mode) with a FlashLayout TSV.The board is custom made , but the HW should not be a problemBut i am running into erorr: ...
I am working with the STM32MP257F-DK using the official Starter Package. Suddenly, the board entered a state where several power rails are disabled. The ST-LINK LED (LD5) is blinking red slowly, and there is no HDMI output (0V on the rail) I have SSH...
For the STM32MP135 series, specifically the STPMIC1A I'm using, can VDD_CORE and VDD_CPU share the same power rail (buck1)?
