Hi,We are using stm32mp157a in our custom board.We are configured SAI for Cortex M in cubemx.But we are unable to get dma interrupt and data through DMA. you can see my code flow below.In main.we are calling below functions.int main(){ MX_DMA_Ini...
Hello Attached is my i2c ioc file and I have connected an ADXL sensor to the stm32mp1 on its Arduino connector(I2C5). ( address: 3A, Chip id value : E5, Chip ID read register : 0x00)I am trying to read this chip id but getting an error at the below...
Hi STI enabled DISTRO_FEATURES_append = "tpm2" in the file ".../layers/meta-st/meta-st-openstlinux/conf/distro/include/openstlinux.inc" as described in the ST Wiki.When building with "st-image-weston" I get the following error message:ERROR: Nothing ...
Hello, I have two questions : (1) Is I2C5 the one on which the peripheral can be connected on the I2C lines on the Arduino connector with the cortex M4? I checked this and it is I2C5.PLease correct me? (2) I was trying to search/look the BSP methods ...
Hello, There may be another variant of this question available but I am reposting it as I couldn't get any success so far redirecting prinf messages to uart4 and viewing them on serial terminal utility.below are the snapshots which shows I have mappe...
Hi,I am working on a functionFS usb gadget based on gmidi. Following the gadget_configfs.rst and using stm32_usbotg_eth_config.sh as starting point was straight forward. After writing the shell script and modifying my device tree configuration to sup...
This is how I would like to use rs485:&usart3{ pinctrl-names = "default", "sleep"; pinctrl-0 = <&usart3_pins_mx>; pinctrl-1 = <&usart3_sleep_pins_mx>; status = "okay"; uart-has-rtscts; linux,rs485-enabled-at-boot-time; rs485-rts-delay-ns = <80...
Hi,Out kit use the chip stm32mp157C.The schematic show the PHY configuration.dts_file_relate2eth.txt: my device tree code related to the ethernet.loginfo.txt: show error information.Please advise how to solve it.Thanks,QiZhang
We are using OpenSTLinux as base distro for configuring and developing product on a custom STM32MP1 based embedded board. We plan to develop some testing and validation plans for the same. Just wanted to understand what sort of testing is carried out...
I have a design based on the STM32MP157C (technically the Octavo SiP) which simulatenously uses PA0, PA1, ANA0, and ANA1. While measuring analog signals on the device, I'm noticing that the CPU is biasing the ANA0 and ANA1 signals -- based on a measu...
