Hi,Is it possible to utilize the PCM1754 DAC as a Sound card with the ALSA Framework on OpenSTLinux?According to the documentation, the PCM1754 functions as a Hardware-controlled DAC, eliminating the need for additional drivers. Therefore, is it nece...
Hello everyone! I am working on a small prototype based on the STM32MP157F-DK2 development board. For convenience, I want to use a GPIO Connector compatible with the Raspberry Pi to power the board (CN2) instead of the USB Type-C (CN6). I have an exp...
We are experiencing an issue where, in approximately 1 in 1000 cases, we don't get a TxRxCpltCallback callback after starting a SPI DMA transfer from an ISR on the ARM-M4 (coprocessor). The transfer appears to have taken place as all the bytes are re...
Dear ST team, Hope you're doing well.We have developed a custom board based on STM32MP151 with emmc. Currently, we are using STM32MP151 for flashing. The problem is each flash is taking around 15 minutes time and it will be a critical issue in our p...
error is logged as > Label or path sram not foundThe DTS file at the failing line reads &sram{ dma_pool:dma_pool@0{ reg = <0x50000 0x10000>; pool; }; }; I'm assuming this is to specify where the SRA...
Hi,I have a problem with hanging up my board occasionally when an issue from the console reboot.I read about and the internet says this is a problem with the EMMC memory's power cycle.So I followed by a linkhttps://github.com/orangepi-xunlong/openwrt...
Hello. We already have a custom board based on STM32MP151CAD3 with an eMMC. The following pins are different with default eMMC pins.SDMMC2_CMD: PA0SDMMC2_D1: PB7 As not default pins are used, we need to update OTP value. Here are my result. OTP3 = 0x...
Hi, let us know, for this development kit,1. Linux customization possible.2. support for development
Hello, I built an image with the following configuration by using the ST wiki pages:STM32MP157D-DK1 Evaluation BoardYocto KirkstoneSTM32MP1-Ecosystem-v4.1.0meta-java layer (branch kirkstone)I have used the following command to create an image:./creat...
Hello, In order to use the non-default QSPI boot locations, my understanding is port0-port3, 4 signals need to be defined in OTP words 3, 5, and 6 based on a similar question about SDMMC1 discussed here:https://community.st.com/t5/stm32-mpu-products/...
