Hi, I am using my custom SOM board based on STM32MP157CAC3 chip. The DDR, SDMMC1, UART4, I2C4 & PMIC configuration is same as of stm32mp157c-DK2 board. even I have used the same pin configuration in my hardware. For USB OTG, I have left USB ID and US...
Hi,I am working on a custom board based on STM32MP157F and I am having some issues with USB and EHCI driver in U-Boot as well as with USB and OTG controller in U-Boot and TF-A.Once Linux is booted USB with EHCI driver works fine, but in u-boot it doe...
hi,i would like to know if there is an API for configuring, starting and stopping the timers (TIM1, TIM2, etc.) i'm interested in setting up a timer as a PWM device. i've come across documentation that talks about functions that can be used to set ...
I would like to configure USB_OTG_HS port as Virtual COM Port(VCP) on stm32mp157f-DK2 board. The board is running STLinux and the host is windows 10. I can see the debug usb port as COM6 on my windows-10 device manager - that works fine. I would li...
I am Korean and a developer with less than a year of experience. Please understand the immaturity of inquiring in the official English language. I am using STM32MP157C-EV1 board. The board has the following settings according to the blog link I refer...
Hello,we are working on the ST32MP1. The SPI3 works fine with the CubeMX software combining the DMA2 and FIFO when the board works in engineering mode. But if I perform the same software loaded by Linux (rproc start), the DMA2 SPI stream stops worki...
I ran into a warning for one section of code that I did not for a different section of code. So I simplified it into two function. I don't see why I get a warning for one and not the other.void test32(uint32_t *data) { uint32_t src_addr = (uint32_t...
Hello, I am working with STM32MP157C-DK2 board and trying to pass messages between the CM4 and the CPU (main processor) using the OpenAMP framework over the com ports ttyRPMSG0 and ttyRPMSG1. On the CPU I have the openstlinux-weston image, and a C pr...
Hi there,I am struggling to understand and achieve a USB gadget with Mass Storage + Serial(cdc-acm) + 1 custom interface with one bulk in and one bulk out though functionfs. Every interface works fine when runs separately. Issue starts when i try to ...
This part uses 354LFBGA package that does not bring out PG4 or PG5 where RGMII clocks are brought out. This would not allow connection to the RGMII_GTX_CLK or RGMII_CLK125 signals.
