Hello! I have just discovered that kit I would like to use to develop a new testing system within the company where I am working. However, I have some questions about it:What kind of additional card could we use to apply 24V to the board's input (I h...
Hy i am using the usart3 from the STM32MP157A-DK1. i orientated myself on the USART driver (https://elixir.bootlin.com/linux/latest/source/drivers/tty/serial/stm32-usart.c).butwhen i want to initialize theport I get following error code “Rs453Network...
I'm using a custom board(with STM32MP151C) with custom device tree, the distribution is built with ST's Distribution Package (st-image-core). Now the bootloader (u-boot v2020.01) freezes while "starting kernel" with some strange errors before. After ...
I have stm32mpdk2 board and trying to interface a uart based peripheral ( nfc) .I have connected Tx , RX , Vdd, GND > pin (12,8,1,6) .tty driver is already enabled in the kernel. and the peripheral on powering up shows the init sequence correctly(led...
With STM32MP157C-DK2, I like to exercise SPI5 hardware, to use this interface to do talk to FPGA and DSP chips. And I need to use SPI5 in both U-boot and Linux runtime, here I got some issues to enable the SPI5 device.1, Within U-boot.How to enable S...
When trying to migrate a project (STM32MP153A) from basic uboot (Ecosystem 1.3) config to trusted (Ecosystem 2.1) system panics when booting TF-A because of SPI6 being enabled and assigned to the nonsecure core.Is this expected behaviour or just a re...
Hi CommunityIn the DT the TIM1, TIM4 and SPI4 are assigned to the M4 and in the pinmux the RSVD is set (DT attached). Booting A7 generates no ERROR during Kernel boot. If the M4 is started from the A7 context the following ERROR Messages occurs for a...
