Actually, we are trying to reset the MAC registers by using DMA mode register (bit 0) in Ethernet section.As per reference manual, we are set the bit(swr bit) to 1 in ETH_DMAMR_REG register. but it is not reset automatically. In software we done // E...
I cannot get the QSPI NOR-Flash to work on my custom board using an STM32MP153CA + Adesto AT25SF128 NOR flash in U-BOOT. I'm working with 5-10-dunfell-mp1-21-11-17 files included on the 3.1.0 ecosystem.The schematic section is shown below:Is not tha...
Hi,my system working fine from EMMC(written through cube programmer). I also have on my board an SD-Card slot and boot configuration pins. Is it possible to upgrade the system through SD-Card to EMMC via dd if=... from rootfs?How to prepare EMMC....r...
I've just made the switch for V4.0.0 (A-TF 2.6, Linux 5.15 but with Barebox instead of U-Boot) using Buildroot as before.I had trouble to bring the system up because of what has been changed in regard to SCMI.The DT node's compatible name was changed...
Does it have a linux driver and is it supported? How can I use it?
Hello,actually, our processor STM32MP153 (dual core) is completely full with the "normal" memory regions regarding the MCUs (M4) code and data. So now, we decided to add the RETRAM_data form ORIGIN = 0x00001000, LENGTH = 0x0000F000 /*60k*/The linker ...
In stm32mp157c-ed1.dts, the MPU pin setting is written in the stm32mp15-pinctrl.dtsi file, but in CubeMX, a node called @pinctrl is created in the generated .dts file and written in it.Why?Can I delete this part and create a ***.pinctrl.dtsi file?
Hello , Can anyone please point me to the example of SPI communication between stm32(F4/L0/L4) with A7 of STM32MP1?A7 could be a driver or any user application but both should be able to send and receive the data over spi.on A7 I suppose it will be S...
Our hardware has an STM32MP151DAx.In order to make use of the Cube Programmer and the boot-via-USB method I need the equivalent of the tf-a-stm32mp157d-ev1-usb.stm32 file but for our hardware.I have worked through the IOC stuff, have DTS files and go...
Hello all ~I have STM32MP157A-EV1 and STM32MP157C-DK2. I want to change system time and keep it. But It is not working well. Below is the test log on EV1.root@stm32mp1:~# date -s "20031025 18:00:00" Sat Oct 25 18:00:00 UTC 2003 root@stm32mp1:~# date...
