Hello everyone,I am trying to replicate this approach to integrate STM32MP1 with an external audio codec. The issue I am facing is that the sub-block SAI-A is generating the bitclock (SCK), while I need it to receive it from the external audio codec....
we are using stm32mp157f-ev1 and we build the weston image for this board.We want to enable the SPI-1 on this boardwe had applied the following patch to enable the SPI-1+&spi1 { + status = "okay"; + pinctrl-names = "default", "sleep"; ...
I ask because I'm starting the project of a converter that receives the video signal via optical fiber and converts it to an SDI output.
Hi,Because dotnet core supports ARMv7, but it doesn't say much clear about ARMv7M. So, I tried to port uCLinux from STM32F7 on my custom STM32H7 board. The OS boots fine but when I ran "dotnet --version", response is "sh: ./dotnet: No such file or di...
I have several questions first one is what is the max clock for I2C, minimum is pointed at this sheet but what is the max?Again for the same sheet for the LCD-TFT controller, I will be using 1.8V LVDS display so fclk frequency will be 45 MHz max righ...
I am asking this question after using the the Developer package of the STM32 Echosystem in orfer to recompile the kernel drivers of the ADC to activate the ADC, how ever i can't figure out how to modify the device tree. i was trying to get this examp...
Actually, we are trying to reset the MAC registers by using DMA mode register (bit 0) in Ethernet section.As per reference manual, we are set the bit(swr bit) to 1 in ETH_DMAMR_REG register. but it is not reset automatically. In software we done // E...
I cannot get the QSPI NOR-Flash to work on my custom board using an STM32MP153CA + Adesto AT25SF128 NOR flash in U-BOOT. I'm working with 5-10-dunfell-mp1-21-11-17 files included on the 3.1.0 ecosystem.The schematic section is shown below:Is not tha...
Hi,my system working fine from EMMC(written through cube programmer). I also have on my board an SD-Card slot and boot configuration pins. Is it possible to upgrade the system through SD-Card to EMMC via dd if=... from rootfs?How to prepare EMMC....r...
I've just made the switch for V4.0.0 (A-TF 2.6, Linux 5.15 but with Barebox instead of U-Boot) using Buildroot as before.I had trouble to bring the system up because of what has been changed in regard to SCMI.The DT node's compatible name was changed...
