I am evaluating different dual-core ARM Cortex-A7 MPUs for their graphical features; one of my requirements is that I need to support a 1280x1024 TFT LCD at 50-60fps using 16 or 24-bit parallel RGB interface.The evaluation kits offer small LCDs below...
If we emulate the MCU watchdog reset on STM32MP1 it works fine. MCU is got restarted and runs after that. SYSRESETREQ assertion (by calling NVIC_SystemReset) works fine with dedicated M4 processor.We wander what can be a problem on STM32MP1 ?
I am interested in the maximum transmission bandwidth between the A7 core and M4 core on the STM32MP1.I did some test using RPMsg framewirk and sent messages with length 496 Byte from the A7 core to the M4 core. Therefore I modified the OpenAMP_raw e...
I connected an external sensor via i2c and modified the device tree dk2 with following addition:&i2c5 { status = "okay"; clock-frequency = <100000>; pinctrl-names = "default", "sleep"; pinctrl-0 = <&i2c5_pins_a>; pinctrl-1 = <&i2c5_pins_sleep_a>...
I built the rootfs according to the instructions at https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package, but the userspace program of gcnano is not installed in the rootfs, the / vendor directory is empty. I need to manually install gcnan...
I used 1GB LPDDR3 at STM32MP157AAA3 chips.but it's only read 512MB:sad_but_relieved_face:
Hello, I am trying to prepare QSPI Flash and eMMC with SD card u-boot on my EV1 board. Is there a document about this?The layout file I am using is FlashLayout_nor-emmc_stm32mp157c-ev1-trusted.tsv:#Opt Id Name Type IP Offset Binary - 0x01 fsbl1-boo...

Hi There,before I go into detail regarding my question I´d like to give some background infos. I have an application in mind that seems like a perfect fit for the STM32MP1 as it would enable me to merge a device which is currently split onto two sepa...
Hello,We are currently building a product using a STM32MP157 processor and are facing multiples discrepancies between the Reference Manual and the STM32MP1 Cube Package.STM32CubeMP1 register memory map :https://github.com/STMicroelectronics/STM32Cube...
