Hi all,I'm writing a USB composite device support (baremetal) for MP135: it must support a custom interface and a CDC profile. Now I'm testing the CDC side connecting the USB cable with a PC: Windows mounts correctly a virtual serial port and I open ...
Hi,I am working on STM32MP133FAFx (I2C Master) for I2C communication with STPMIC1 IC (I2C slave) fast mode(400KHz) and HSI clock(64MHz). I2C->TIMINGR = 0x00C0216CFor writing data TXIS flag is getting send and I am writing the register but when trying...
Hello We are using STM32MP157A processor in our custom board. Now we are implemented IWDG1 in Cortex A7 processor. The IWDG1 bit is not going to set after reset the processor with Watchdog timeout.we checked in following registers• RCC BOOTR...
Hi ST Team,We have developed a board based on the STM32MP257F. Currently, I am focusing on the audio section. We use an I2S port to connect to a codec called ES8388 chip. You can find the schematic in the attached picture,the connection between ES838...
Dear Readers,I try to flash my board in Debian 6.1 on 64bit version in a VirtualBox.Whatever I doSTM32_Programmer_CLI -l usbalways fails.I have donesudo apt-get install libusb-1.0-0cd xyz /Drivers/rules sudo cp *.* /etc/udev/rules.d/I rebootet, but a...
Description: I'm working with the MYIR MYD-YA157C board, based on the STM32MP157C, and experiencing an issue with UART data reception. When receiving data via UART, the same 10-byte buffer is repeated multiple times (50-60 times) instead of getting f...
Hi,I am working on STM32MP133FAFx (I2C Master) for I2C communication with STPMIC1 IC (I2C slave) fast mode(400KHz) and HSI clock(64MHz). I2C->TIMINGR = 0x00C0216CI am trying polling method in bare-metal environment for communication in I2C.Below is m...
My current application uses 2 USB ports, both connected to USBPHYC (STM32MP157F). The OTG one is used for programming using CubeProgrammer.My new revision requires 3 USB ports, 2 host and the programming port.According to https://community.st.com/t5/...
Dear all,I'm trying to run a TA application on STM32MP157C-DK2 board. Im using the STM32MPU Developer Package to build the TF-A and the OP-TEE.I've built the TF-A using the command below:make -f $PWD/../Makefile.sdk TF_A_DEVICETREE=stm32mp157c-dk2 TF...
I am trying to connect to audio codecs to give 4 channel of audio on a MP257. Can I connect SAI2.SCKA TO BCK on both , SAI2.FSA to LRCK on both, SAI2.SDA to DIN on the first and SAI2.SDB to DIN on the second.My concern is the clocking, can I common b...
