Can I use sd card programmed on stm32mp157f-dk2 board on custum board(embedded stm32mp157d)?
I have two boards stm32mp157f-dk2 and my custum board(embedded stm32mp157d).I know that the difference stm32mp157f and stm32mp157d is simply security part.And my custom board don't have C-type connector because of issues in parts supply.So, After plu...
The STM32MP157 is configured for ADC acquisition within the M4 core, and the ADC data is carried using the DMA method. It turns out that the sample rate and the sampled data are correct when debugging with the development board MCU start-up method Debug,
The two graphs above are the data obtained from different cores. The left side is the MCU method start, the sampling rate is 1.6M, the acquisition of 1KHz signal, the acquisition of 1600 points is correct; the right side is the EMMC from the A7 core ...
Resolved! Is there an example of how to perform DDR data bit swapping as described in AN5122?
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...
Resolved! How can I get the MMC timing spec higher than sd high-speed?
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 ...
How to configure Size and speed for DDR3 in stm32mp1
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...
Resolved! STM32MP157CAA3 + MT41K512M16VRP-107
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...
Is it possible to power the board without using the USB-C ?
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 ...
I want to know how to use ST33G1M2 .
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.
