We are using LPDDR2 and have wired the data bits as per the ST provided example STM32MP15XXAD_LPDDR2x16-Example-A01_Schematic.PDF (attached)We have swapped the same bits in the DQ15:8 byte as per the PDF but I can't find anything to tell me how to pe...
Hello,I am having difficulties with the MMC bus and the external SDIO wifi module. We are using the wifi module jody-w263 from U-blox with the OSD32MP1, and the communication with the module works, but it is quite slow. The wifi module is capable of ...
Hello,We are using DDR3 for our baremetal application in stm32mp1.we have completed the initialization sequence followed by the application note AN5168 provided by ST.After completion of initialization sequence we are trying to write the data into DD...
Hi,I try to combine STM32MP157CAA3 with DDR3L 8Gbits density. I modified cubemx to support 8Gbit memory and recompiled the Openstlinux mp1-v22.11.23 kirkstone.The problem is that DDR3 is detected in the first stage U-Boot but not executed 2nd stage U...
On the STM32MP157-DK1 schematic there is a note to say "WARNING - do not supply 3V3,5V from Arduino shield", even though it looks as though pin 5 on CN16 is electrically connected to 5V_VIN via a 0R resistor.It's going to be very inconvenient to use ...
The ST33xxxx with backside terminal.My question is about this back side terminal .Which is this terminal conect to GND or Vcc.OR ,Is this used open. thankyou.
I am using an STM32MP151 in linux (5.4.56) and therefore using the DTS to setup some GPIOs i need.I have difficulties setting up PUSH_PULL | PULL_UP configuration in the DTS for my GPIO, while, after linux has booted, using devmem i am successfull in...
I am trying to transmit variables via the uart2 serial port from GY-521(mpu6050) library, however, all my attempts are unsuccessful. typedef init in the main.c:MPU6050_t sensor_data;main.c area to put HAL_UART_Transmit(): while (1) { MPU6050_Read_Al...
hi st expert:I'm updating my yocto version to Ecosystem V4.1.0, but I can not compile suceess in wsl ubuntu20.04, this is error log:log.do_rootfs.23400 as follew:How should this problem be solved? thanks B&RTao
Hi,I am working on the implementation of a AI algorithm in a heat pump. My first choice was the SPEAr320 MPU: it is outdated though, it doesn't have enough resources and any FPU. Which MPU should I choose for this application ? that is to say inferen...
