I built u-boot for stm32mp157a-dk1 board with basic boot mode:Defconfig: stm32mp15_basic_defconfigDevice Tree: stm32mp157a-dk1I got this error at starting u-boot and if I try to read/write from/to OTP register:stm32mp1_clk_get_id: clk id 69 not found...
.. previously I had STM32MP157D-DK1 on work, there DFU works Ok,but now bought STM32MP157F-DK2 for home, there's no any sign of connection,reset button do not affect on STlink led, meanwhile stlink/2 itself - works and other USBs - is Ok.Maybe it's a...
Hi!I am using a STM32MP157C-DK2 board to communicate via CAN. To do this, I have created a program in STM32CubeIDE and set the FDCAN parameters:Classic mode.150KB/s nominal baud rate.HSE clock source (24MH) I have been testing in engineering mode and...
hi ST expert:I am porting openSTDroid to my mp157 board,i use prebuilt kernel img&dtb and android kernel can boot normal,but when i update the kernel, it cant boot normal,can you help me solve this problem?my compile cmd:build_kernel mrproperbuild_...
we are working on STM32MP1 in Linux .we are trying to access the EMMC from Linux by using following commandsudo fdisk -l but EMMC device is not detecting/accessing. Please help us in this regards.
Hi,I was downloading and installing Distribution package for the 1st time following this link: https://wiki.st.com/stm32mpu-ecosystem-v3/wiki/STM32MP1_Distribution_PackageAs I want version openstlinux-5.10-dunfell-mp1-21-03-31After source sync there ...
Hi, according to "AN5256 Application note", I think VTT -DDR termination resistors circuitry is ok to be removed. Does it mean all things relate to VTT DDR below are also safe to remove out of the design? Many thanks
On STM32MP157f-DK2, when use UART4 which is default connect to STLink, STM32CubeProgrammer connect and work perfectly in boot serial mode.But when I change to different port (like USART3, pin PB10 and PB12 (also supported by default), STM32CubeProgra...
After reading documents, I understand the practical boot sequence of STM32MP1 is BOOTROM->TF-A->U-boot->Kernel->file systemIn my use case, I prefer to use Windows and write code in bare metal, without U-boot and device tree involved. 1 I think the b...
