Hi dear all,I'm looking for dual ethernet examples to implement with my stm32mp157d MPU , but I couldn't find anything on the internet.I've seen that there is no STM32 with dual ethernet interface but i want to add dual ethernet and fiber ports to my...
Hi,I'm using a custom buildroot build (2021.11) with linux 5.15.13, on the stm32mp157f-ev1 board.I can load an .elf M4 firmware into the M4 core and start it, using /sys/class/remoteproc/remoteproc0However, I can't use the debugging feature of STM32C...
I am using MB1407C (stm32mp157x-DK2 extension board with touch-screen) connected to my custom board. When board is booting I am getting the "ST life.augmented" screen on the U-boot and black screen when kernels starts. Also I am getting the telnet co...
hi,I am working with a custom board based on the STM32MP157C. I use a lan9303 chip which is acting as a switch for ethernet. In the linux kernel, there are no problems with the ethernet but I can't get it to work in u-boot. Even when I use the same D...
Hi all,I am not familiar with STM32 platform but the DFSDM ADC feature seems to do exactly what I want (external delta-sigma modulator + digital filtering). I bought a STM32MP157C-DK2 board and started playing with it. But, I can't find any working e...
Hi All,i am using stm32mp1 with i2c on sgtl5000 codec and control lines are over carrier i2si am getting kernel soc sgtl5000.c error sgtl5000 0-000a: Error reading chip id -6<STM32_PINMUX('A', 15, AF5)>; /* I2S1_WS */<STM32_PINMUX('Z', 0, AF5)>, /* I...
I'm using the bootlin buildroot branch: st/2021.02.I want to run a certain function on init of the Uboot (board_init function), like the ones used for the DK1 and DK2. My problem is that the function doesn't seem to be called. I have tried to debug t...
Hello, i'm trying to use M4 kernel from A7 kernel worked under linux.I've started with openSTlinux distro and it works well (i can upload firmware to M4 using rproc), but for some reasons i need to make a very small distro (less than 16 mb). For this...
Hi,I'm working the stm32mp157c som and trying to boot external quad spi flash (cypress S25HL512T). I added this to dts. &qspi { pinctrl-names = "default", "sleep"; pinctrl-0 = <&quadspi_pins_mx>; pinctrl-1 = <&quadspi_sleep_pins_mx>; status = "...
Looking at the clock in the MX Device Configuration Tool it says 204 to APB1 Timer Clocks (MHz).To get to 10000 Hz I have to divide 204 MHz by 20400. Fortunately there are a bunch of ways to do this. But on the first try I tried Prescaler 51Counter ...
