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...
