Hello,We are using STM32157AAA3 Processor in our custom board and Microchip Ksz9893 switch for ethernet and the switch is configured using i2c.when we are trying to ping ethernet in RGMII mode in U-Boot v2022.10-stm32mp-r1 we are getting the Rx-clock...
Hello everyone,I've installed STM32CubeIDE and I've created a new STM32 project with STM32MP1x (in this case STM32MP131AAE3) as target but in the project there are only two directories (DeviceTree and Drivers).There isn't a source directory ("src") w...
Hello everyone,I have to convert a neural network into optimized C code for STM32MP1x. Is it necessary using OpenSTLinux (so X-Linux-AI) or is there an other way to get it?
Hello! Although, the OS is not supported, I'd be happy to get any clues on my relatively generic question.I have realized, that TEX remapping registers (PRRR and NMRR) values are hardcoded in Linux kernel source..equ NMRR, 0x40e040e0I'm particularly...
I'm having trouble in bringing up my custom board. I've made a custom device tree using CubeMX and adding the sections as described in "Lab-MP15_FromPartNumber_To_BasicDeviceTree_with_CubeMx". I can program fsbl-boot and fip-boot, but i'm not able to...
I've been trying to cross compile pyzmq for my stm32mp135f-dk and I'm facing issues with it. I've ran the script to setup my environment for the SDK. And made the required changes in the setup file. Here's my stackoverflow post with the logs as well....
Hi,I am using a PCM3060 codec connected to a STM32MP135 MPU over I2S1 and I2C, and compiling STM Linux (v6.1) (along with STM's version of TF-A, Optee, and U-Boot) using Buildroot.I had some trouble getting ALSA to output to the codec, it kept giving...
The LPTIM_TypeDef struct that is used throughout many of the HAL header files contains a few RESERVED fields that cover unused address offsets in the peripheral's memory map.The first of these, RESERVED1, is declared as uint16_t. I believe that this ...
Hi, I tried the Hello World application on Cortex-A7, I want to try linking my custom application library in this example. Can I do that?I changed the print_hello function and calling another function from my custom library.I tried linking custom lib...
