Hi, I'm working with the STM32MP157 and I'm trying to interface it with 4 lanes DSI display. the problem is that the STM32MP157 support only DSI with 2 lanes. In the other hand, I can't program the controller of the display (JD9365DA-H3) to switch wi...
Hello,I want to send in reliable way messages from M4 core to A7 core (in my case its the HW is STM32MP157 -DK2 ). The problem is that when A7 core is busy, the messages are truncated.The quesiton is how M4 core would know that A7's buffers are full?...
Hello,I want to upgrade my hardware to new openstlinux kirkstone release november 2022.First test on eval board was successful.I have written custom device tree files and compiling for tf-a, u-boot, fip and kernel is fine.However when I try to flash ...
Hello,Using a custom board loosely based on STM32mp157F-DK2we are using boot0 and boot2 pins.According to documentation,boot mode configuration is as follows;Boot Mode BOOT2 BOOT0Recov/DFU 0 0Nor 0 1Reser...
Hello We've designed a custom board based on 157F-DK2 with device tree generated from the custom CubeMX project (included in case somebody like to review it.)After flashing it in DFU mode with the image created from openstlinux sdk, TF-A bails out of...
stm32mp157f-dk2 is not embedded jtag connector,but i want to use jtag debugger.st-link(stm32f103cbt6) embedded in stm32mp157f-dk2 has jtag pin(T_JTCK, T_NRST, T_SWO, T_JTMS)Q1. Can't I use jtag with only ST-LINK USB CONNECTOR (5 pin)?Q2. what should...
I'm using spi5 and my device tree settings are &spi5 { pinctrl-names = "default", "sleep"; pinctrl-0 = <&spi5_pins_a>; pinctrl-1 = <&spi5_sleep_pins_a>; #address-cells = <1>; #size-cells = <0>; num-cs = <1>; is-decoded-cs = <0>; cs-gpios = <&gp...
Hello,I'm writing to inquire if there is documentation/support for developing non-linux operating systems using the STM32 MPU discovery kits. So far I've only found Cube support and documentation for ST's custom linux distro. Obviously, a processor b...
Hello,I am working on a custom board based on stm32mp157 and I have the need to enable the PWR_USB_SW through the ST PMIC. So far, I identified the bit VBUSOTG_ON in register BST_SW_CR (0x40) but I had no success in configuring it via devicetree or v...
